Converting a string of tuples to a list of tuples in Python

Question

How can I convert \"[(5, 2), (1,3), (4,5)]\" into a list of tuples [(5, 2), (1,3), (4,5)]

I am using planetlab shell that doe

Answer 1

'join' replace following characters '()[] ' and creates string of comma separated numbers

5,2,1,3,4,5

'split' splits that string on ',' and creates list strings

['5','2','1','3','4','5']

'iter' creates iterator that will go over list of elements

and the last line uses a list comprehension using 'zip' to group together two numbers

it = iter("".join(c for c in data if c not in "()[] ").split(","))
result = [(int(x), int(y)) for x, y in zip(it, it)]

>>> [(5, 2), (1, 3), (4, 5)]
