IF-ELSE --> CONDITION2: condition1 is false and condition2 is true IF-ELSE --> ELSE: all conditions are false 上面的关系图展示了多个if else语句的逻辑关系,当条件1为真时执行第一个代码块,当条件1为假且条件2为真时执行第二个代码块,当所有条件都为假时执行最后一个代码块。 多个if else语句的...
Nested decisions that works like the Russian dolls,and sometimes re-indenting as the end of both this block and the end of this block. EG: x = 42ifx>1:print('More than one')ifx < 100:print('less than 100')print('all done') Two-way decisions:if[conditions]: [printcxxxxx]else: [...

We can also create more complex conditions(对条件进行组合). If c is a condition, then not c is also a condition. If we have two conditions c1 and c2, then we can combine them to form a new condition using conjunction(合取) and disjunction(析取): c1 and c2, c1 or c2. ...
Note: In the Python documentation, a group of statements defined by indentation is often referred to as a suite. This tutorial series uses the terms block and suite interchangeably.Consider this script file foo.py:Python 1if 'foo' in ['bar', 'baz', 'qux']: 2 print('Expression was ...
