有人能帮我解决简单的列表python问题吗?

如果要检查字符是否为数字,可以使用 isdigit 功能

my_list = ["a3", "b3", "aa"]

def erase(lista):
    only_chars = []
    for word in lista:
        result = ''.join([w for w in word if not w.isdigit()])
        if result:
            only_chars.append(result)

    return only_chars


result = erase(my_list)
print(result)

它将打印:

['a', 'b', 'aa']

数字 结合 any :

my_list = ["a3", "b3", "aa"]

def erase(lista):
    only_chars = []
    for word in lista:
        if not any(w.isdigit() for w in word):
            only_chars.append(word)

    return only_chars


result = erase(my_list)
print(result)

现在,结果是:

['aa']
