First knowledge of Python (6)-Conditional judgment

If

Conditional judgment is to execute a program fragment when a condition is true, otherwise execute another.

3if age >= 18:    print(‘your age is‘, age) print(‘adult‘)else: print(‘your age is‘, age) print(‘teenager‘)

So the basic format of the IF statement is:

<条件判断1>:    <执行1>elif <条件判断2>: <执行2>elif <条件判断3>: <执行3>else: <执行4>

If the statement is judged from the top down, if it is in a certain judgment True , the statement corresponding to the execution of the sentence, then ignore the remaining elif andelse。
