[英]find multiple string occurrences in Python
is there a way to do something like this? 有没有办法做这样的事情?
if ['hel','ell','orl'] in 'hello world' :
I want to see if all of these strings occur in the word. 我想看看是否所有这些字符串都出现在单词中。 If possible in a shorter way than completely writing a multiline foor loop. 如果可能的话,可以比完全写入多线foor环更短的方式。
if all(substr in 'hello world' for substr in ('hel','ell','orl')):
# all are contained
The advantage of all()
is that it stops checking as soon as one substr
does not match. all()
的优点是,只要一个substr
不匹配就会停止检查。
A multiline for
loop is the correct way to proceed. 多行for
循环是正确的继续进行方式。 If you don't like how it looks in your code extract it into a function and then you just have a single line function call for the same thing. 如果你不喜欢它在代码中看起来如何将它提取到一个函数中然后你只需要一个单行函数调用同样的东西。
