Question

I’m working on a school project in which we need to create a solution for 8-puzzle problems using the a* algorithm. Anyways, I would like to ask a user for an input say:

123  
456  
7 8

How do I separate those and store in a list? I know how to store it on a list, my problem is the separation.

sampleList = ["1", "2", "3", "4", "5", "6", "7", "0", "8"]

Answer 1

One approach would be to access the digits one at a time while they were still in string form.

>>> input = ['123', '456', '7 8']
>>> sampleList = []
>>> for digit_str in input:
...     for digit in digit_str:
...         sampleList.append(digit)
... 
>>> sampleList
['1', '2', '3', '4', '5', '6', '7', ' ', '8']

Now since this is for school I’ll leave it to you to work out how to change the space into a zero 🙂
