Case insensitive: ['a', 'Andy', 'beautiful', 'day', 'fishing', 'is', 'Today', 'went'] Case sensitive: ['Andy', 'Today', 'a', 'beautiful', 'day', 'fishing', 'is', 'went'] Python sort list by lastname In the following example, we sort the names by last name. ...
For example, here's a case-insensitive【不区分大小写】 string comparison: >>> sorted("This is a test string from Andrew".split(), key=str.lower) ['a', 'Andrew', 'from', 'is', 'string', 'test', 'This'] The value of thekeyparameter should be a function that takes a single ar...
str.casefold() is the way to go for case-insensitive comparisons. If you work with text in many languages, a pair of functions like nfc_equal and fold_equal in Example 4-13 are useful additions to your toolbox. Example 4-13. normeq.py: normalized Unicode string comparison """ Utility...
We then lowercase s if case_insensitive is True, and then we proceed to check if it is a palindrome. In order to do this, we compare the first and last characters, then the second and the second to last, and so on. If at any point we find a difference, it means the string isn...
To set the encoding argument, you use the "utf-8" string. However, you can use any other valid encoding, such as UTF-16 or cp1252, which can be represented as case-insensitive strings. Note that "utf-8" is the default value of the encoding argument to .decode(). It’s important ...
