    Define a function called repeat_middle which receives as parameter one string (with at least one character), and it should return a new string which will have the middle character/s in the string repeated as many times as the length of the input (original) string. Notice that if the original string has an odd number of characters there is only one middle character. If, on the other hand, if the original string has an even number of characters then there will...

    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...
