The Python if statement is like most procedural languages.
It takes the form of an if test, followed by one or more optional elif ("else if") tests and a final optional else block.
The tests and the else part each have an associated block of nested statements.
The general form of an if statement looks like this:
if test1: # if test statements1 # Associated block elif test2: # Optional elifs statements2 else: # Optional else statements3
All parts are optional, except the initial if test and its associated statements.
Thus, in the simplest case, the other parts are omitted:
if 1: print('true')
To handle a false result, code the else:
if not 1: print('true') else: # ww w . j a v a2s . com print('false')
