You are passing 55 as a string.

And what were you trying to do with with second print statement?... You might want to work with python's f-strings
Ok thanks.
Re: Learning Programming. (my Nairaland Journal) by syluck(m): 6:22pm On Nov 03

Since, you have converted the string (input function returns string value of whatever is been given) to integer.

Your comparison should be
if user != 55:
--snip--

not "55"

Oh I will try that
Thanks

After much learning and practises, I came across Functions in python. And I decided to use it to solve the number (4).
And it gave me two answers different from the answer proposed sad

Python's '/' always give floating point number (decimal). If you run that 10 times you might get ten different numbers, the only difference will be the numbers after the decimal.

Use '//' to get a non-decimal answer instead.



Try to download an introductory book to python, all these and more are discussed thoroughly there.

Hi there, my good friend. Glad to see you are making progress.
For question number 4, I think you misread the question.
1. You see that dot between 47 and 48? It is actually a multiplication operator, not a decimal point. It is placed at a height that is mid height of the two numbers, rather than being placed on the baseline e.g. 47*48 not 47.48 I will apportion some blame to the authors though.
2. We can prove this by manually performing the calculation:
(512 - 282) / (47*48 + 5) = 230/(2256 + 5) = 230/2261 = 0.101724900 = 0.1017 (to 4 decimal places)
Let me just drop a piece of advice which will help you going forward. When you have a problem you are trying to use an algorithm to solve;
understand the problem perfectly, solve it manually to confirm that you know the expected solution. In programing, when programs are tested - you provide known inputs, then you check that the program produces the expected output.
3. You don't need a function or integer division to solve this problem.
4. I also noticed you had some issues with parentheses. In Mathematics there is BODMAS (Brackets Of Division Multiplication Addition and Subtraction) to determine precedence of operations, but in programing we have PEDMAS (Parentheses Exponentiation Division Multiplication Addition Subtraction). To force a certain precedence use parentheses.

//Sample program
result = (512 - 282) / ((47 * 48) + 5)
print(f"The result of the calculation is: {result}" )

Don't give up, you are on the right track.

For question 1, you are simply printing the same value four (4) times. The characters (*) can be stored in a string, after which you can the print.
E.g. my_string = '*******************'
Print my_string the required number of times.

For question 2, you are printing two (2) different patterns, which can be stored in two (2) different strings.
Example
pattern1 = '*******************'
pattern2 = '* *'
You should know what to do from here.

Question 3 is slightly different. There is a clear pattern here, each new line has a new character added at the end of the string. You can simply use string concatenation (+).
Example
custom_string = '*'
print(custom_string)
custom_string = custom_string + '*' # or custom_string += '*'
print(custom_string)

....you know the rest.

Thanks.

Python doesn't increment like that.

Why don't you write it out for the dude. This write up might end up confusing him the more.

Naijasensie has said it all.

You can use the round function to approximate it to 4 d.p.

It is called augmented expression not increment.
Python doesn't have the incrementing by 1 and decrementing by 1 syntax in javascript.

Javascript supports augmented expression, incrementing by 1 (i++) and decrementing by 1 (i--)

I guess you're fast to make corrections when I didn't do anything wrong. cheesy

What I mean was post/pre increment/decrement.

Python doesn't do that. But it does augmented expression.

This is a concise answer to your question.

1. One of the reasons functions exist is so you can easily vary parameters. In that sense, it's good programming to pass in arguments when defining the function which you can easily vary later on.
2. Also apply parenthesis using the BODMAS notation

Finally, it seems the question asked for your answer to be in 4 decimal places. So take note of the 'round' method I called, it's an inbuilt python function that accepts two arguments, (float, no of dp)

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.

Wow, this is wow!
Your coding shows how learned you are in programming. I'm yet to grasp all this algorithm in coding but I believe with time I will be able. Thanks for these. It will help me a lot

1, Thanks for clarifying me on that. I thought it was a decimal point. Never knew it was a multiplication operator.
2, I will clearly work on it once more. And I really appreciate the advice.
3, A part of me told me that, but I really tried running that code using for loops, while loops, etc, I just couldn't until I came across functions then I decided to give it a try one more time and boom! it kinda gave me a clue of what I was doing. But it was giving me different answers which did not correspond with the proposed answer. Also, thanks for the advice. I will stick to them.
4, Never knew about PEDMAS. But I knew that python work according to precedence. Just that I didn't really know how that works.

I really appreciate your input.

Lastly, do you have a WhatsApp group or telegram channel for beginners so I could link up and be dropping my troubles as well.

Unfortunately, I don't have links for beginners. Just keep on doing what you are doing. May I suggest studying algorithms and data structures, it will help broaden your understanding a bit.

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)

Then, number (11) and (14)

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.

Then, number (11) and (14)

def sequence_function(num):
if num==0:
return num+1
elif num==1:
return num
else:
return sequence_function(num-2) + sequence_function(num-1)

len=int(input("Enter len of terms: "wink )
for i in range(len):
print(sequence_function(i), end='\t')

This is the answer to your number 9, improve on it by adding constraints against negative numbers. If a user enters a negative number with the code above, it'll produce an error. Use a simple if statement to make sure that doesn't happen.
