Python uses Unicode code points to determine character order, meaning uppercase letters sort before lowercase. The comparison works by finding the first differing element; if one sequence is a prefix of another, the shorter one is considered less. This behavior is practically useful for multi-key sorting: placing values in tuples in priority order lets Python's built-in sort handle hierarchical ordering automatically, such as sorting alumni by year, then last name, then first name. ## Full article daily.dev links to this article rather than hosting it.
