Python获取列表中不在lis中的项

Question

我有一个国家名单： 国家=['United States', 'Canada', 'France', 'Japan', 'Turkey', 'Germany', 'Ghana', 'Hong Kong', 'United Kingdom']

我想得到所有不包含任何国家的行。 这是我的密码：

with open('file.txt') as f:
    lines = f.readlines()[1:5]
    a = [line.split(':') for line in lines]
    for country in countries:
        for line in a:
            if country not in line:
                print(line)

打印（行）打印所有行，而不是打印不包含国家/地区的行

Answer 1

你可以试试这个：

data = [i.strip('\n').split(":") for i in open('filename.txt')]
countries = ['United States', 'Canada', 'France', 'Japan', 'Turkey', 'Germany', 'Ghana', 'Hong Kong', 'United Kingdom']
final_data = [i for i in data if not any(b in countries for b in i)]
