if
statements are used for truth value testing. In this lesson, you learned that you don’t need to explicitly compare a value to True
or False
, you can simply add it to the if
statement:
Bad
if value == True:
print 'truthy'
if value2 == None:
print None
Good
if value:
print 'truthy'
To compare a value to False
, use the not
operator:
if not value1:
print 'falsy'
Explicitly check for None
:
if value2 is None:
print None
