We’re open sourcing it. The library is called “Fuzzywuzzy”, the code is pure python, and it depends only on the (excellent)difflibpython library. It is available onGithubright now. String Similarity The simplest way to compare two strings is with a measurement of edit distance. For exam...

Jaro distance: Jaro distance is a string-edit distance that gives a floating point response in [0,1] where 0 represents two completely dissimilar strings and 1 represents identical strings. 2.Soundex以及根据发音对字符串进行比较的方法 Soundex:Using Fuzzy Matching to Search by Sound with Python...
Python的int可以无限大的,所以没有真正实现了大数乘法。 python do really well in some aspects. Python Version:Knowledge 1、Python中的//应该是向下取整的意思 a//b,应该是对a除以b的结果向负无穷方向取整后的数 5//2=2(2.5向负无穷方向取整为2),同时-5//2=-3(-2.5向负无穷方向取整为-3) ...

I have a love-and-hate relationship with regular expressions (RegEx), especially in Python. I love how you can extract or match strings without writing multiple logical functions. It is even better than the String search function. What I don’t like is how it is hard for me to learn and...
Range matching is often used for character ranges ('a'...'z') but that won't work in Python since there's no character data type, just strings. Range matching can be a significant performance optimization if you can pre-build a jump table, but that's not generally possible in Python ...
I’ll explain the need for @unchecked in a moment. Finally, we can use pattern bindings with a regular expression to decompose a string. Here’s an example for parsing (simple!) SQL strings: // src/script/scala/progscala3/patternmatching/AssignmentsRegex.scala scala> val c = """\*|[...
