4. Check if an item exist in tuple 要检查一个元组是否包含给定的元素,我们可以使用'in'关键词和'not in'关键词。 检查项目是否存在于元组中 Tuple = ("a", "b", "c", "d", "e", "f") if "a" in Tuple: print("Yes, 'a' is present") # Yes, 'a' is present if "p" not in T...
*args是可变参数,args接收的是一个tuple; **kw是关键字参数,kw接收的是一个dict。 以及调用函数时如何传入可变参数和关键字参数的语法: 可变参数既可以直接传入:func(1, 2, 3),又可以先组装list或tuple,再通过*args传入:func(*(1, 2, 3)); 关键字参数既可以直接传入:func(a=1, b=2),又可以先组装di...
