Karleb:
Let say x has an initial value of 2.

When you do x += 2 it a short hand for x = x + 2, which will give you 4.

That means

x = x + 2 'and' x += 2 are thesame thing.

You can substitute the addition sign for any other arithmetic sign in python.

x = 4

x *= 4 #16

x //= 2 #8

x -= 3 #5

x %= 2 #1

x /= 1 #1.0



Concised and informative...

I appreciate your help

Q1 - First understand what range() does.
range(start, stop, step). The range function produces values from the start value, upto but NOT INCLUDING the stop value. That is;
for i in range(1,10)
supplies i with values 1,2,3,4,5,6,7,8,9. Assuming prompt = 10, and I want a range of values from 1 to 10 (10 inclusive), instead of range(1, prompt) I would rather use range(1, prompt + 1)

Q2 - factorial = factorial * i is a programming concept you will see a lot of. It means multiply the value referenced by "i" with the current value referenced by "factorial", then let the new value referenced by factorial be (factorial * i)

Q3 - s += i is the same as s = s + i, same explanation as in Q2

s *= i is the same as s = s * i,
s -= i is the same as s = s - i,
and so on.

Thanks bro...

Ok guys, I'm stuck in the while loop.

Want it to print exactly what the for loop does

Your print statement is not under the while loop.

Two things are wrong:

1. You have to print str for each iteration as you've done for the for loop, which is print(str[i])
2. The print statement should come before i+=1

To avoid an infinite loop, you must always increment i (i+=1) till the condition which is (i<len(str)) can no longer be satisfied

Q. Write a program that asks the user to enter a password. If the user enters the right password,
the program should tell them they are logged in to the system. Otherwise, the program
should ask them to reenter the password. The user should only get five tries to enter the
password, after which point the program should tell them that they are kicked off of the
system.

I used both loops, for and while loop

Great to see you are making progress. However, always remember proper indentation in your Python code, else you will get logic errors in your code (if you don't encounter syntax errors first).

Hi, glad to see you are getting good mileage on your journey. Not trying to come across as snobbish, but I just want to correct an impression you have.
Variables are not containers, a variable is more like a label that points to a value. Values (integers, floats, boolean, strings) are stored in memory, so a variable points to a memory location. Don't just take my word for it, here is proof. There is a function in Python called identity - id(). id() is used to return the memory location of a particular value.

Exercise
Create two or more different variables, then assign the same value to each variable.

my_var = 34
another_var = 34
third_one = 34

print(id(my_var))
print(id(another_var))
print(id(third_one))

The value returned should be the same for the three print functions. The actual value will also depend on the particular system you run the code on.
Hope I have not confused you though, because this concept is very important.
The author is right;
Variables are temporary data stores

Following ur progress op.

looking at people's code and trying to understand it is the best way to learn imo.

I remember reading udemy-dl on GitHub and I remember reading this one too https://github.com/bocadilloproject/bocadillo
Learnt how to use slots in python from that project.

Some python tips for you.

Install ipython on ur command line for easy code completions.

Use tab to trigger code completions on ipython. (Works on jupyter notebook too)

Inspect using dir()

Hustle till you no longer need to introduce yourself-

Deriving some intensive understanding from the above mentioned, I've come to realize that I need to keep pushing forward in my daily activities. To keep pushing forward till that moment when I don't need to stand up infront of someone or group of persons to introduce myself in a manner that will be awkward to my audience. A manner in which my audience will have that indifference feeling about me and wondering who am I and my mission. So in order not to allow this scenario come to play, I've decided not to be complacent.

A complacent satisfaction with the present knowledge is the chief barrier to the pursuit of knowledge - B H Liddell Hart.

In pursuit of more knowledge, I decided to involve myself into programming. This, I believe is a step to a milestone of success I will achieve.

I developed interest in programming at a time but later lost interest because to be a successful programmer you need a good mentor. If I can have one here that can guide me I am willing to learn and become a programmer. Can you help?

One important thing I learnt from again is that, any variable with two UNDERSCORES at the beginning and two at the end shows how important it is and shouldn't be altered.


This is wrong sir, variables that starts with underscores are priavate variable hence you need to access them from methods and not directly, when you get to object oriented part of programming, you will understand. For now disregard them and don't use them while learning the basics.

I started full stack dev on Microverse too! Right now I’m still at the pre application stage via Odins project!


Learning HTML
CSS
Java script
And I’m loving it!

Hopefully we’ll be able to work on a project together!
For now, Let me go back to my laptop! wink

So yesterday, I was able to decipher and crack open what command line is all about. Creating new directories and files using command line.

Judging by the command line guide, I know what these performs,

pwd
cd
cd .
cd ..
ls
-a
-l
rm
rm -r
mkdir
touch
rm
Etc

What learning resources do you use?
