Sort case-insensitive Python

Case-insensitive Sorting By default, the sort() method sorts the list in ASCIIbetical order rather than actual alphabetical order . This means uppercase letters come before lowercase letters.

Sorting on the basis of the ASCII values differentiates the uppercase letters from the lowercase letters, and results in a case-sensitive order . Although the results in the Ascending order column might at first appear somewhat unpredictable, they are not.

A case-insensitive search is more comprehensive, finding “Language” (at the beginning of a sentence), “language”, and “LANGUAGE” (in a title in capitals ); a case-sensitive search will find the computer language “BASIC” but exclude most of the many unwanted instances of the word.
