DJHANDSOME:
am following


ah really would love to learn three pro. languages before this year runs out


java


python


C

have an OCA in JAVA , Learnt C with Linux. It's not about number of programming languages you know though. What matters is how fluent you are with them. What matters MOST is knowing how to solve problems. Na there be the real koko. Seeing a problem, breaking it down to little parts, and building a solution from the pieces.

PRACTICE
Using the Python Shell, calculate the following, find the results of the following expressions.
– 8 + 5 * 4 – 3.
– 10 raised to power 8.
– The remainder when 6 is divided by 5.
Computers read instructions from left-to-right, line-by-line. The parenthesis symbol “()” when used around a part of an expression, indicates to the computer to evaluate its contents first. To understand this, run the following expressions.
– (8 + 5) * 4 – 3.
– 8 + (5 * 4 – 3).
– 8 + 5 * (4 – 3).
– 8 + (5 * 4) – 3.

You no tell us say we must put "print" before the maths.

UncleSnr:

You no tell us say we must put "print" before the maths.

If you use Shell mode, you don't need to.

If you type it in a script, you'll need the print() to display the answer. I'll throw more light on this in a future lesson.

sonOfLucifer:

Will update this weekend.

Waiting for the update please.

No noise pls. Oya kontunu oga mi

That's one of the problems of Nigerian programmers. Jack of all trades

It is so obvious that many nigeria youth mostly "teen" do aspire to become a leet programmer but ony the strong and bold people learn it to the hardest part. It is the game for the survival and fitness

Programming no be beans talk. So if you know you wont create time to learn it fully better quit now at the beginning of the road to avoid wasting your leisure time learning noting.

Anyway am a java developer but am eager and desire to port into python cause it seems java is very complicated. #Son_of_lucifer i would be happy if you add me up on facebook with this my name. Though am into beingnner aspect of python now through the help of this python king called "pythonian"

Sorry guys. Got banned on Friday. Poor timing.

i lost all of my friends on twitter because i typed "i am a hardcore luciferian". na wa for my naija brothers

LESSON 6
In the previous lesson, we learnt to work with numeric values in Python. Most times, the values we may want to represent could be a combination of alphabets, numbers and other symbols.

We may want represent data such as your e-mail address (something@google.com), your name(Kelechi) or your matriculation number (“MA01/4432”). Each alphabet, number or symbol is called a character. A string is a combination of characters.

CHARACTERS
A character is any letter, number, space, punctuation mark, or symbol that can be typed on a computer. There are a few terms you should be conversant with if you want to be a solid programmer.

Whitespace
If you hit the tab key or space bar on your keyboard, it moves the cursor a little distance forward. The Tab key and Spacebar on your keyboard produce what is called whitespace. Think of them as invisible characters. They do not show on the screen but they represent space. The spacebar moves the cursor a single space. The tab key usually moves the cursor four spaces.

Newline:
Hitting the Enter key on your keyboard moves the cursor to a new line. This is called as new line character and most programming languages represent it as “\n”. We’ll talk more on this later.

CREATING A STRING IN PYTHON
To create a string value in Python, enclose the value in double quotes (” “) or single quotes(‘ ‘).

Open IDLE in Shell mode. Type in each value and enclose in quotes. Make sure the quotes match, else you’ll get an error. That means if it begins with a double quote(“), end it with a double quote(“).



Similar to numbers, string values also have operators that can be used to combine, modify or manipulate them.


WORKING WITH STRINGS
Open Idle in Shell Mode and enter the following code.
"Hello"
"The name's Bond " + ", James Bond
"Knock" x 2
"Knock"/2

Strings in Python
Confused? Don’t be. Let’s go through each of the lines.
On the first line, we entered a name and enclosed it in double quotations to indicate it is a string value. Python recognizes text within the quotation marks as strings. If you do not enclose the text in quotation marks like we did on the second line, an error will occur.

On the third line, we did something really strange. We combined two strings into one using the mathematical operator(+). This is known as concatenation.

Understanding how this third line works is crucial to solidifying our understanding of datatypes. The datatype of a value determines what operators can be applied to it, and the manner in which these operators are applied.

Numeric datatypes allow us to add, subtract, multiply and divide values. If you use the addition symbol(+) on numeric values, it will treat them as numbers and add them.

With strings, the addition symbol does something different. It combines both strings and returns a new string value. So “Choco” + “milo” will return "Chocomilo” and “2” + “3” will return “23”.

The multiplication operator(*) also acts differently when used with strings. On Line 4 of our prgram, we multiplied a string by two. The multiplication operator(*), when applied to strings, repeats the string. For example, “Nawa” * 3 will return “NawaNawaNawa” as result.

CLOSING
Understanding operators and how to use them is vital. A list of operators in Python can be found at this link. As we progress, we will learn about other operators that can be used to make comparisons between two values and other interesting functions.

So far, we haven’t been able to do much with these values. In the next lesson, we will learn how to store values so we can reuse them or make changes to them. Variables… coming up next…

We are moving forward.
Thanks for d update.

Am enjoying this... Waiting for the next update

Pardon me. This lesson might be a bit rushed.My weekend schedule looks tight, but I wouldn't want to delay the thread. Na sleep eye I use type this lesson. Please, if you notice any mistakes, or if the explanations need to be improved, do let me know.

LESSON 7
So far, so good. We've learnt how to create and use numeric and string values. In this lesson, we'll talk about variables and how to use them.

WHAT ARE VARIABLESS

Open IDLE in Shell Mode. Enter the following lines of code, and hit Enter.
Notice what happens everytime you enter. Shell Mode evaluates the instruction you've entered and immediately displays or prints the result to your screen.
Hitting Enter after typing an instruction in Shell Mode tells the computer to execute the given instruction.
Let's assume we would like to store or 'hold' the result of an expression(or a value) so we can manipulate it later. In simple English, we want our program to 'remember' a value, to 'hold on' to a particular value. This is where variables come in.

A variable is a name that refers to a value. All we are saying is 'oh boy, hold this value for me, if i call you, give me the value'. To create a variable, you type a name and put the '=' symbol after it.

If you're a Mathematician, you might have read the symbol as 'equal to'. As a programmer, that is wrong. The '=' symbol is an assignment operator. It assigns the value of whatever expression is on the right hand side to the variable on its left.



Be careful when picking a name for your variable. Make sure the name describes the value/data it refers to. There are three general rules you should remember when creating variables.

Variables names must start with a letter or an underscore, such as: _underscore. underscore_
The remainder of your variable name may consist of letters, numbers and underscores. olodo2, wannabec0der. …
Names are case sensitive. case_sensitive, CASE_SENSITIVE, and Case_Sensitive are each a different variable.
Alright, let’s try some code so we get a hang of this. In Shell Mode, type the following

1 + 2


Both numbers are added and the result 3 is displayed on screen


sum = 1 + 2

Both values are added to produce a new value 3. This new value is then assigned to a variable called sum. Note that no result is printed. Type
sum at the prompt to see the value of sum

sum

Variables can also be used in expressions. You must assign a value to a variable before using it in an expression. An error will occur if you attempt to use a variable before it has been assigned a value.

sum * 3

sum = sum + 4

Weird? Not really. You should read assignment statements from the right. On the right side, the value of sum is added to 4 and the new value is then reassigned to sum. This is important.

A variable can only refer to a single value at a time. If you reassign a value to a variable, the variable will refer to the new variable it’s been assigned to. Type sum at the prompt to get its new value.


sum

Notice in the screenshot what happened when I put a space between the “+” and “=” operator. It throws a syntax error. There should be no space between += or *= and so forth.

Now try these. See if you can figure out how they work. Type sum after running each statement

sum += 2

sum *= 3

sum /= 4

These operators are also assignment operators. They’re shorthand methods of updating variables. The first one is similar to “sum = sum + 2”. It updates sum by adding 2 to i. The second one line updates

Variables can also hold string values. Try the following code in your shell prompt.


"James" + "Bond"

firstname = "James"

lastname = "Bond"

firstname + lastname

firstname + " " + lastname

fullname = firstname + " " + lastname

fullname += " Samson"

Cool. Now, you should have a proper understanding of what variables are and how they are used. Slowly, we are learning the building blocks of Python programs, and with time, we will combine this knowledge to write meaningful and useful programs. In the next lesson, we will talk about functions.

Ok sir. We are following.
Thanks.

following boss.

I love python!

Python is quite easy to learn if you take your time to learn vb.net for example. Then you can build on that.

Download ...learnpythonthehardway.pdf
notepad++
emmets plugin for notepad++
and use windows powershell on ur pc....

Hope it helps.

son of lucifer i be ur secret follower oh.been using python since april due to a course i did in my sch.....i discovered it has more diverse applications than the normal mathematical abilities.pls put me in the know.

Hey, heeehe thanks.

Yeah, Python is easy to use. You can use it for data analytics and to create simple desktop apps too.

This tutorial I'm running will take you through the basics. Hopefully, we'll create a calculator app at the end of the course.

i actually did something similar using the scriptmode but dont know how i would convert it to an app?.i would be patient though.do u mind if i pm u

Hi, developers in the house. Is there a way I can extract my file Explorer from my phone to an external storage so that it can be copied to another mobile phone?

Well done sir!

bro @sonofekwensu. i must say you are doing a very wonderful job. and i like how young Nigerians are sharing knowledge to help ech other.

i'm new to programming and i've been learning python. before i started, one pro like that told me that python is useless in Nigeria that i should learn c#, saying it's more useful.

the thing is that c# is too complex for a newbie like me with no programming knowledge.
so thank my stars that i did some reserch on my own and decided to stick to python.

my question is how far will i go with python(i intend to go in so deep that i may not have time to learn other languages like java c# etc..)? although i want to learn php, css and mysql for web developmet.

am i on the right path?

God bless your TrueHeart
Python is a solid programming language for beginners and learners. I'd say only you can limit yourself. Python is becoming popular in data science, and also ethical hacking.
If you're interested in web development, Django is a Python framework used in web development. Think of frameworks as a language built on the language to make it easier. Na so I sabi explain am o.

I'd say start with Python. HTML and CSS aren't difficult to learn. I personally don't consider them programming languages.

What's your main interest?

thanks for your response.

my main interest are in web development, software and app development.

so you're saying if i learn django there's no need for php and css?

aside from python being good for beginners. would you recommend it for anyone who wants to go pro in programming?
