Python Fuzzy Matching with FuzzyWuzzy — ELI5
Have you ever texted a friend “wanna get piza?” and they knew you meant pizza? They didn’t need perfect spelling to understand you.
FuzzyWuzzy does the same thing for computers.
The problem with exact matching
Computers are picky. Ask a computer “Is ‘Jon Smith’ the same as ‘John Smith’?” and normally it says “No! They’re different!” Even one tiny letter changes the answer.
That’s annoying when you’re working with real-world data. People spell things differently, make typos, or use nicknames.
FuzzyWuzzy to the rescue
FuzzyWuzzy is a Python tool that gives a score from 0 to 100 for how similar two pieces of text are.
- 100 means they’re identical
- 0 means they have nothing in common
- Anything above 80 or so usually means “close enough”
Different ways to compare
FuzzyWuzzy is smart about how it compares:
- Simple ratio: just checks the whole text straight through
- Partial ratio: checks if one text fits inside the other (great when one is shorter)
- Token sort: sorts the words first, then compares (catches “Smith John” vs “John Smith”)
- Token set: only cares about which words are shared, ignoring extras
Where people use it
- Cleaning up messy spreadsheets with duplicate names
- Matching addresses that are written slightly differently
- Finding products in a catalog even with typos in the search
One Thing to Remember
FuzzyWuzzy gives computers the human ability to recognize that two things are “close enough” to be the same — even when the spelling isn’t perfect.
