Need Help With Writing a program

[Hafiz75]

Please can some help me write a program for the question below. I have tried my very best.

Question:

a. the user is asked how many lines of RLE compressed data they want to enter
b. the program should check that the number entered is greater than 2 and if it isn’t display a suitable error message and get the user to keep re-entering the number until it is valid
c. if the user entered a valid number, they then enter the compressed data one line at a time until they have entered the specified number of lines
d. once all the compressed data has been entered, the program decompresses the data and displays the ASCII art image

 

Code i have:

Split=(list(input("Enter string: ")))
            Split.append("")
            a = 0
            for i in range(len(Split)):
                try:
                    if (Split in Split) >0:
                        a = a + 1
                    if Split != Split[i+1]:
                        print(Split,a)
                        a = 0
                        
                except IndexError:
                    print()

So what's the problem here? And do you have any sample inputs with their expected results?

You have to use code tags when posting code, click the <> button in the editor and paste your code into the box and insert it into post.

Which part of the four things you listed does the program not do?

 

Pre-emptively I'm looking at this one:

once all the compressed data has been entered, the program decompresses the data and displays the ASCII art image

Which makes no sense to me taken as-is. I'm assuming the input is pre-determined for you and that's what you're entering?

Then let's back up. Instead of trying to do everything, let's look at one item and make sure it works before working on the next one.

 

Please note since this looks like a homework assignment, I'm not going to provide you with any code that solves the problem. I may provide code that can be used, but it's up to you to figure out where it goes.

So let's get this one started:

This should help get you started: https://www.python-course.eu/python3_input.php (I'm also assuming this is Python 3 by the look of things)

rleline=int(input(“How many lines of RLE compressed data do you want?))

Yes, however, int() fails if you give it a non-numerical character. So make sure you have a case to handle this.
