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 built-in functionality, etc.
The reason I'm asking this is because I learned about int("string") from here. But when trying bool("string") it always returns True:
>>> bool("False") True

To convert String to Boolean, use the parseBoolean() method in Java. The parseBoolean() parses the string argument as a boolean. The boolean returned represents the value true if the string argument is not null and is equal, ignoring case, to the string "true".
Given a string list, convert the string truth values to Boolean values using Python. Input : test_list = ["True", "False", "True", "False"] Output : [True, False, True, False] Explanation : String booleans converted to actual Boolean.
We convert a Number to Boolean by using the JavaScript Boolean() method. A JavaScript boolean results in one of the two values i.e true or false. However, if one wants to convert a variable that stores integer “0” or “1” into Boolean Value i.e “true” or “false”.
You can convert True and False to strings 'True' and 'False' with str() . Non-empty strings are considered True , so if you convert False to strings with str() and then back to bool type with bool() , it will be True .
Really, you just compare the string to whatever you expect to accept as representing true, so you can do this:
s == 'True' Or to checks against a whole bunch of values:
s.lower() in ['true', '1', 't', 'y', 'yes', 'yeah', 'yup', 'certainly', 'uh-huh'] Be cautious when using the following:
>>> bool("foo") True >>> bool("") False Empty strings evaluate to False, but everything else evaluates to True. So this should not be used for any kind of parsing purposes.
