Import therandom module:This module implements pseudo-random number generators for various distributions. Seedocumentation. The random module in Python offers a handychoice()function that simplifies the process of randomly selecting an item from a list. By importing the random module, you can directly...
print("Randomly picked fruit:",random_fruit) 1. 至此,我们已经完成了整个"Python List Random Pick"的实现。下面是完整的代码示例: AI检测代码解析 importrandom fruits=['apple','banana','orange','kiwi','watermelon']random_fruit=random.choice(fruits)print("Randomly picked fruit:",random_fruit) 1....

正如在“注释位置参数和可变参数”中提到的,__iterable中的两个下划线是 PEP 484 对位置参数的约定,由 Mypy 强制执行。这意味着你可以调用sum(my_list),但不能调用sum(__iterable = my_list)。 类型检查器尝试将给定的参数与每个重载签名进行匹配,按顺序。调用sum(range(100), 1000)不匹配第一个重载,因为该...
