With Python 3.10, thematch-casestatement provides an alternative for certain conditional checks. This new feature is particularly useful when you have a series of conditions to check and want to avoid the nestedif/elsestatements. Thematch-casestatement is more concise and easier to read, making y...
Here, we haven't used indentation after theifstatement. In this case, Python thinks ourifstatement is empty, which results in an error. Python if...else Statement Anifstatement can have an optionalelseclause. Theelsestatement executes if the condition in theifstatement evaluates toFalse. Syntax...
In the above case Python evaluates each expression (i.e. the condition) one by one and if a true condition is found the statement(s) block under that expression will be executed. If no true condition is found the statement(s) block under else will be executed. In the following example,...
"Silver Member" if user_points >= 500 else "Bronze Member" ) print(get_user_status(1001)) # Gold Member 在这个例子中,我们用三元运算符替换了if-elif-else链。这种写法可能使得代码更加简洁和易于阅读,尤其是当有少数个条件需要判断时。三元运算符是 Python 中一种非常有用的工具,可以减少代码的冗余,...

Python程序语言指定任何非0和非空(null)值为true,0 或者 null为false。 Python 编程中 if 语句用于控制程序的执行,基本形式为: if 判断条件: 执行语句…… else: 执行语句…… 1. 2. 3. 4. 其中"判断条件"成立时(非零),则执行后面的语句,而执行内容可以多行,以缩进来区分表示同一范围。
