#Write a function called mock. mock should take one #parameter, a string. You may assume that the string will #have only lowercase letters and spaces. # #Your function should return the same string, but any letter #at an even index should be converted to uppercase. # #For example: mock("abcd efgh ijkl") would return #"AbCd eFgH IjKl". # #Remember, you can use the ordinal function ord() to get the #number associated with a single letter. For example, #ord("a") returns 97. The number associated with lowercase #letters is always 32 larger than the number associated with #the equivalent uppercase letter. ord("a") is 97, and #ord("A") is 65. ord("z") is 122, and ord("Z") is 90. # #Remember, you can use the character function chr() to #convert a number back to a letter. For example, chr(65) will #return "A". # #HINT: Treat all characters the same initially, then worry #about taking care of spaces afterwards. #Write your function here!
