Python If Else statement usage

Format of an If statement
The statement block must have the same indentation.
Statement block must be indented more than if,elif,else

# If conditions are true, EXECUTE statement block 1,# Otherwise, if condition 2 is established, EXECUTE statement block 2# Other cases EXECUTE statement block 3# Elis and else part are optional if condition 1: statement block 1ELIF Condition 2: statement block 2else: statement block 3
Second, the example

i = 10if i = = 3:print ' i is 3. ' Print "I also execute after if." "Elif i < 3:print ' I < 3 ' else:print ' other cases. ' Print ' prints end. '
III. Matters of note

1. There is no switch statement in Python, and switch can use If...elif...else to implement 2. If, elif, the else must have a colon (:), after which the code needs to add a layer of indentation
