with python how to check alomost similar words

Str1 = "The supreme court case of Nixon vs The United States"
Str2 = "Nixon v. United States"
Ratio = fuzz.ratio(Str1.lower(),Str2.lower())
Partial_Ratio = fuzz.partial_ratio(Str1.lower(),Str2.lower())
Token_Sort_Ratio = fuzz.token_sort_ratio(Str1,Str2)
Token_Set_Ratio = fuzz.token_set_ratio(Str1,Str2)
print(Ratio)
print(Partial_Ratio)
print(Token_Sort_Ratio)
print(Token_Set_Ratio)

fuzzy lookup in python

from fuzzywuzzy import process
str2Match = "apple inc"
strOptions = ["Apple Inc.","apple park","apple incorporated","iphone"]
Ratios = process.extract(str2Match,strOptions)
print(Ratios)
# You can also select the string with the highest matching percentage
highest = process.extractOne(str2Match,strOptions)
print(highest)
