How do I handle such list inputs?

I take such an input from the user-

enter image description here

Then i try to split it using comma and append it into a list as numbers.

But whenever I do so , it gives out an error and the only stores "20,340,2".

Notice how the last number for the first line is 223, however, my list only stores 2 and ignores the 23 at the end, even though i've used comma to separate the elements. Same for 789 as well (next line). It stops at 78 and ignores the 9 below, although it is the same number Can somebody please help me take a such inputs and separates each element properly using commas and stores it in a list as numbers? Thank you.

If in fact this is coming from an input file that you read it would look like:

  input = '120,340,2\n        23,456,678,78\n       9,456'

when read.

This results in a number of different problems. One of which is that you have read until the second delimiting single quote to make it work.

Then you get something like:

input = '120,340,2\n        23,456,678,78\n       9,456'
input = input.replace(" ","")
input = input.replace("\n","")

Like this?

input='120,340,200,240,21,2,9,5,300'
input.replace(" ","") #removes spaces

input_array=input.split(",") #creates array, although they are still strings

for i in range(len(input_array)): #for every number in the list, replace the string with the number.
    input_array[i]=int(input_array[i])

print(input_array)

If you really want to allow numbers with spaces in them, you could start by just removing all spaces from the string:

>>> s = '120,340,2 23,456,678,78 9,456'
>>> s.replace(' ', '')
'120,340,223,456,678,789,456'

From there, you can split on commas and parse the parts as numbers.
