Match string in a list python

Question

i have a python list as follows

 List=['\Opt\mydata.cab','\my\ginger','\my\garbage','\my\hfs']

i have a string as given below

strin1="mydata\opt\mydata.cab"

is there any easy way to match the string in list '\\Opt\\mydata.cab' one line without a for loop like given below

if strin1 in List:
                print(strin1)

Answer 1

No, Python doesn't have anything like that. But you can always use any function like this

if any(item in strin1 for item in List):

Still, this will look for exact match. If you want case-insensitive match you can convert both sides to lowercase.

The advantages of using any are

1. You don't have to roll your own function

2. It short-circuits immediately when the condition is satisfied for the first time

3. It works with any iterable

If you want to get the item which matches, you can use the next function like this

next(item for item in List if item in strin1)

You can also pass the default value to be returned if there is no match, like this

next(item for item in List if item in strin1, None)
