Additionally, the documentation lists this class on the built-in functions page. This is one of those cases where practicality beats purity.When it comes to evaluating strings, you have that an empty string is always falsy, while a non-empty string is truthy:...
# Calling functions with parameters add(5, 6) # => prints out "x is 5 and y is 6" and returns 11 # Another way to call functions is with keyword arguments add(y=6, x=5) # Keyword arguments can arrive in any order. 可以在参数名之前加上*表示任意长度的参数,参数会被转化成list: ...
In this example, you use .lower() to convert the target substring and the original string into lowercase letters. This conversion tricks the case sensitivity in the implicit string comparison.GeneratorsGenerator functions and generator expressions create memory-efficient iterators known as generator ...
normeq.py: normalized Unicode string comparison """ Utility functions for normalized Unicode string comparison. Using Normal Form C, case sensitive: >>> s1 = 'café' >>> s2 = 'cafe\u0301' >>> s1 == s2 False >>> nfc_equal(s1, s2) True >>> nfc_equal('A', 'a') False Using ...
staticmethod transforms functions into a "no-op" descriptor, which returns the function as-is. No method objects are ever created, so comparison with is is truthy.>>> o1.staticm <function SomeClass.staticm at ...> >>> SomeClass.staticm <function SomeClass.staticm at ...>Having...
A complete documentation of all functions can be found here. Note that from RapidFuzz 3.0.0, strings are not preprocessed(removing all non alphanumeric characters, trimming whitespaces, converting all characters to lower case) by default. Which means that when comparing two strings that have the ...
