Python
The Python "<" and ">" comparison operators can be used to compare which string variable has a greater value based on comparing the ASCII codes of the characters in each string, one by one. To take some examples: "tets" > "test" returns True because the third letter of the first string, "t", has a greater value than the third letter of the second string, "s". "testa" > "test" returns True because—while the first four letters in both words are...
