Python:将字符串变量与多个子字符串进行比较

Question

我是 Python 的新手，正在尝试从 Perl 学习 Python。在 Perl 中，如果我想将一个字符串与多个子字符串进行比较，我将使用以下内容:

sub matchCity {
    my $cityName = shift;
    print "$cityName is a valid city name\n" if ($cityName =~ /kyo|par|omba/);
}

matchCity('tokyo'); # tokyo is a valid city name
matchCity('paris'); # paris is a valid city name
matchCity('bombay'); # bombay is a valid city name
matchCity('chicago'); # Doesn't print anything

我如何在 python 中执行此操作？

Answer 1

你实际上不需要正则表达式:

>>> def matchCity(s):
...     if any(r in s for r in ('kyo','par','omba')):
...         print s, 'is a valid city name'
... 
>>> matchCity('tokyo')
tokyo is a valid city name
>>> matchCity('paris')
paris is a valid city name
>>> matchCity('bombay')
bombay is a valid city name
>>> matchCity('chicago')  # doesn't print anything
>>>
