Hello bro, sorry to disturb.

Please I need a better understanding of question number (9). I've tried so hard to understand what's it all about but I just keep getting a blank idea.

Then, number (11) and (14)

naijasensei:


Question 9 is about a sequence referred to as the fibonacci sequence. It begins with two numbers: 1, 1. Subsequent numbers in the sequence are gotten by adding the two previous numbers together. For example, the third number is: 1 + 1 = 2. The fourth number is: 1 + 2 = 3. The fifth number is 2 + 3 = 5, and so on. Your program should request for the user to input the number of fibonacci numbers they want. E.g. inputting 3 should produce 1,1,2 while inputting 5 should produce 1,1,2,3,5.
One way of solving this problem is by using a loop. You will loop as many times as the user requests for, but for the first and second pass through the loop you will print(1).

Question 11 is about patterns, there are two major string patterns - the one with 19 asterisks and the one with 2 asterisks separated by 17 spaces. From the diagram, the default width is 19 asterisks while the default height is 4 asterisks. If a user requests for a box that is 40 asterisks wide by 6 asterisks high, you would use a for loop to print the asterisks 40 times in 6 passes - a nested for loop.
E.g.
for i in range(1, height+1):
for j in range(1, width+1):

Let me see what you will come up with.

Thanks for this input. I won't lie, it took me a while before understanding this

naijasensei:


No shame in that. Some of the concepts are a bit abstract, so it might take a while to understand. Whenever you get stuck, just take your time, relax, do something else, then return to the problem.

Greetings too.

I started learning Programming using python programming language. There are many others but if you like python, then u should begin with it. Below is the link to a thread of python video tutorials. It's quite concised and easily understandable.

Came across this and I tried running the code.

Number 2 and 3 precisely. I'm having problem on both.

In Number 2, I ran the code according to the best of my knowledge but the only issue is having both the Fahrenheit and celcius on both (uppercase, lowercase, first letters both capital and small)

Then for number 3, I just need to understand how to implement the -273.15 when coding.

Thanks

naijasensei:


Why are you using the eval function in your code?

syluck:

According to the pdf I'm using to work on, it has eval throughout. I kinda decided to use it though

For question 3, you are to use if...elif...else blocks
If you have a variable, temp, pointing to where the temperature in °C is stored. Then:

Point of note, I am only showing this to give you an idea. In practice, in a program, be careful when comparing floating point (decimal) numbers. Floating point arithmetic is not as straightforward as integer arithmetic.

syluck:

Does this automate the 273.15 to -273.15?
Cos that's really my problem. How to run the code inserting the -(minus) operator

I'm just glad I'm improving day by day

Vecto:
Well done bro. Coding on mobile can be quite stressful, eh?

What pdf are you using btw?

Vecto:


Sorry do you code on mobile?

syluck:

Thanks bro.
Here is the pdf name

Thanks bro.

naijasensei:


Say what? You're using a 2012 material?

syluck:


Suggest a better one for me please

naijasensei:


Think like a computer scientist.
Automate the boring stuff with Python.

Make sure you get the latest editions. Even the one you are using, I suspect there might be a newer version.

Bro, on god sometimes the simplest algorithms are the hardest to code

Please can you help me out on number 10 and 12

Semtu:


I'll give you hints for number 10, you learn better my figuring things out yourself. You'll need to collect 10 inputs from the user by calling input() through a loop. Outside the loop, create an empty list then append each input to the list while the loop is still valid. Once you've collected the inputs to a list, you can easily play with the python list by calling sorted(). This will sort the list elements in ascending order. Meaning that indexing the first element of the list would be the lowest since the values are sorted while the last would be the highest. To find the average, you can sum the list then divide by the len. Apply similar logic to the rest.

For the second part, this is one way to work through it.
import random
score = [ ]
number=random.randint(1,11)
trials=5
while trials>0:
```indent```guess=int(input('guess the number between 1 to 10: ')
```indent```if guess==number:
```indent``````indent```score.append(10)
```indent```else:
```indent``````indent```score.append(-1)
```indent```trials-=1

print(sum(score))

naijasensei:


Nice, great work.

For Q12 though, I believe score shouldn't be a list, rather it should be of type int. So:

score = 0
number = random.randint(1,10)
#different from random.randrange(1,11)

Because of this:
score.append(10) should be score += 10
score.append(-1) should be score -= 1

Thanks.

Bro, there's this python concepts I really need to understand how it works....
I'll list then below:

1: for i in range (2, prompt+1):

Here, I know "prompt" could be a variable where a value is assigned to.....then, (2) is where we want the loop to start from.... My difficulty is understanding what +1 after the prompt stands for....
Like the example above I listed is used when running a code for "divisors of a number*...

2: for i range(1, num+1):
Indent""""""""factorial = factorial * i

Here, the +1 appears again.... But this time around it's the "factorial * i".... Pls I need to understand this concept really good.....

Lastly:

3: for i in range(1, prompt+1):
Indent"""""""""if(prompt %i ==0)
Indent"""""""""s += i

Here, I understand what prompt is, %i is, ==0 is, and s is... The problem is, "+=". I still don't understand vividly what's that all about...in short, u can explain the whole concept "s += i" to me please....

PS: i know that
+ is an addition operator
* Is a multiplication operator
= a equal sign operator ( mostly used to assign values to variables and vice versa)

Karleb:
In python for loop, the range function doesn't loop to the end of the value naturally, to enable it do this, you have to add 1 the value.


range(1, 4) will print out. 1,2,3 in a loop. So to let it loop to 4 you'll add 1 to 4 to make it 5.


That is, range(1, 4 + 1) will print 1,2,3,4. That is thesame thing as range(1, 5).


In the case where the integer is stored in a variable is when you see something like range(1, myValue + 1).


myValue = 4
for i in range(1, myValue + 1):
print(i)


That loop will print 1,2,3,4.


I think this range thingy is a bug turned feature in python because when you loop through a list, you don't have this problem.
