convert lists of string tuples to lists of tuples

Question

I am facing a small problem in python which I am not able to solve quickly.

How to convert a = ['(100,9),(200,10)'] (list of tupled strings) to a = [(100,9),(200,10)] (list of tuples)

I tried:

- [tuple(word) for word in a]
- a.strip("'")
- a.replace("'", " ")

None of above mentioned solutions are working for me.

Substitute *"tuple"* for *"dictionary"* when reading... Your string will become a tuple of tuples, but I'm sure you can figure out how to flatten it to whatever you need. — jonrsharpe, Nov 18 '15 at 14:32

Use literal_eval func from ast module.

>>> from ast import literal_eval
>>> a = ['(100,9),(200,10)']
>>> list(literal_eval(a[0]))
[(100, 9), (200, 10)]
