I have the following code

num1 = 10
someBoolValue = True

I need to set the value of num1 to 20 if someBoolV

Answer 1

For the future time traveler from google, here is a new way (available from python 3.8 onward):

b = 1
if a := b:
    # this section is only reached if b is not 0 or false.
    # Also, a is set to b
    print(a, b)
