  • python - What is the correct syntax for else if? - Stack Overflow
    In python "else if" is spelled "elif" Also, you need a colon after the elif and the else Simple answer to a simple question I had the same problem, when I first started (in the last couple of weeks) So your code should read:

    expression1 if expression2 else expression3 if expression4 else expression5 # and so on A note on usage: Note that every if must be followed with an else People learning list comprehensions and generator expressions may find this to be a difficult lesson to learn - the following will not work, as Python expects a third expression for an else:
  • python - if else in a list comprehension - Stack Overflow

  • python - Pythonic ways to use else in a for loop - Stack Overflow
    Without using break, else blocks have no benefit for for and while statements The following two examples are equivalent: for x in range(10): pass else: print "else" for x in range(10): pass print "else" The only reason for using else with for or while is to do something after the loop if it terminated normally, meaning without an explicit break
