遍历List Python

Question

I am trying to see if a string I have is similar to any of the strings in a dictionary in python. When I am looking for exact matches, I can do this:

stringList = []
if (myString in stringList):
    #do something

Looking for similar matches using Python Levenshtein is the best I can come up with (I'm sure with some errors).

stringList = []
for i in range(len(stringList)):
    if distance(myString, stringList[i]) < 2:
        #do something
    else:
        #do something else

Is there a better way? Thanks.

Use the difflib module.

difflib.get_close_matches(myString, myList)

Answer 2

it's more pythonic like this :

stringList = []
for item in stringList:
    if distance(myString, item) < 2:
        #do something
    else:
        #do something else

If you don't care what string is close enough, you can use the min function:

if min(distance(x, myString) for x in stringList) < 2:
    # do something
