Convert True/False value read from file to boolean

Question

I\'m reading a True - False value from a file and I need to convert it to boolean. Currently it always converts it to True even if the value is set

Answer 1

Just to add that if your truth value can vary, for instance if it is an input from different programming languages or from different types, a more robust method would be:

flag = value in ['True','true',1,'T','t','1'] # this can be as long as you want to support

And a more performant variant would be (set lookup is O(1)):

TRUTHS = set(['True','true',1,'T','t','1'])
flag = value in truths

Answer 2

You can do with json.

In [124]: import json

In [125]: json.loads('false')
Out[125]: False

In [126]: json.loads('true')
Out[126]: True
