如何根据不同的布尔值更改变量？

if condition:
    # 当条件为真时执行的代码块
else:
    # 当条件为假时执行的代码块

is_sunny = True
if is_sunny:
    weather = "晴天"
else:
    weather = "阴天"
print(weather)  # 输出：晴天

switch expression:
    case value1:
        # 当表达式等于value1时执行的代码块
        break
    case value2:
        # 当表达式等于value2时执行的代码块
        break
    ...
    default:
        # 当表达式不匹配任何case时执行的代码块

day_of_week = 3
switch day_of_week:
    case 1:
        weekday = "星期一"
        break
    case 2:
        weekday = "星期二"
        break
    case 3:
        weekday = "星期三"
        break
    default:
        weekday = "其他"
print(weekday)  # 输出：星期三
