Python提供了两种循环语句:for循环和while循环。 for循环用于遍历序列(例如列表、元组、字符串等)中的每个元素。for循环的基本语法如下: for variable in sequence: # 在这里执行循环体代码 其中,variable是一个变量名,用于存储序列中当前遍历到的元素;sequence是一个序列,可以是列表、元...

Using a membership test to replace a compound Boolean expression with several or operators is a useful technique that allows you to simplify your code and make it more readable.To see this technique in action, say that you need to write a function that takes a color name as a string and ...
Note: For a deep dive into how Python’s membership tests work, check out Python’s “in” and “not in” Operators: Check for Membership. Membership tests are quite common and useful in programming. As with many other common operations, Python has dedicated operators for membership tests. ...
