This example demonstrates how to use the any and isalpha functions to check if a character string contains a letter from the alphabet. Let’s check our first character string my_string1: print(any(c.isalpha()for

alphabet是一个字符串,它包含 ASCII 字母表的所有 26 个小写字母。调用even_items()和传递alphabet返回字母表中交替字母的列表。 Python 字符串是序列,可用于循环以及整数索引和切片。因此,对于字符串,您可以使用方括号even_items()更有效地实现相同的功能: ...
