I want to find string similarity between two strings. This page has examples of some of them. Python has an implemnetation of Levenshtein algorithm. Is there a better algorithm, (and hopefully a python library), under these contraints.
Would something other than Levenshtein distance(or Levenshtein ratio) be a better algorithm for my case?

Comparing strings using the == and != The simplest way to check if two strings are equal in Python is to use the == operator. And if you are looking for the opposite, then != is what you need. That's it!
The way to check the similarity between any data point or groups is by calculating the distance between those data points. In textual data as well, we check the similarity between the strings by calculating the distance between one text to another text.
Using String. equals() :In Java, string equals() method compares the two given strings based on the data/content of the string. If all the contents of both the strings are same then it returns true. If any character does not match, then it returns false.
String Comparison using == in PythonThe == function compares the values of two strings and returns if they are equal or not. If the strings are equal, it returns True, otherwise it returns False.
I realize it's not the same thing, but this is close enough:
>>> import difflib >>> a = 'Hello, All you people' >>> b = 'hello, all You peopl' >>> seq=difflib.SequenceMatcher(a=a.lower(), b=b.lower()) >>> seq.ratio() 0.97560975609756095 You can make this as a function
def similar(seq1, seq2): return difflib.SequenceMatcher(a=seq1.lower(), b=seq2.lower()).ratio() > 0.9 >>> similar(a, b) True >>> similar('Hello, world', 'Hi, world') False If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
