importing a list of numbers into python script

[snippsat]

Thank you again Bolofred. The split operation seems to have done the trick with len returning 5. I have attempted to put the 5 numbers into a list with
list = [s].

Read and split on , in one go,then have a list with with string,than can also do one more step with int() to get integers if needed.

with open('movedata.txt') as f:
    lst = f.read().split(', ')

Test.

>>> lst
['100', '-100', '200', '-200', '200']
>>> [int(i) for i in lst]
[100, -100, 200, -200, 200]
