Converting from a string to boolean in Python?

Question

Does anyone know how to do convert from a string to a boolean in Python? I found this link. But it doesn't look like a proper way to do it. I.e. using a built in functionality, etc.
The reason I asked this is because I learned int("string"), from here. I tried bool("string") but always got True.

Answer 1

bool of any string is True unless the string is empty, i.e. bool(''). What exactly do you want to do? maybe there is a better way

Answer 2

foo = 'True'

bar = foo.lower() == 'true'

Answer 3

From my understanding you want to do this:

 

def getBoolValue(boolean_string):

        if boolean_string.lower() == "false":

            return False

       elif boolean_string.lower()== "true":

             return True

       else:

             return boolean_string # or whatever you want to return (exception?)

##usage##

 

bool_string = "True"

bool_string = getBoolValue(bool_string)

 

Like Arghavan A. said above bool() simply checks the string for emptiness which is why you get true for bool("False"). However I wouldn't advise creating the function above because string == 'True' is already really simple and I can't image you'll need to be doing to0 many checks like this
