Function name Function description Function Function output(s) / input(s) return value(s) get_sentences() Returns the number of sentences in the text. Тext Number of sentences get_words() Returns the number of words in the text. Text Number of words get_punctuations() Returns the number of punctuations in the text. Тext Number of punctuations print_letters() Prints the number of occurrences of Block of text Occurences of letters case-insensitive letters in the text. in the text Case-insensitive means that a letter is the same whether it is uppercase or lowercase. The function should print the letters in decreasing order of the number of occurrences. If multiple letters have the same number of occurrences, print the letters in alphabetical order. Separate groups of letters with the same number of occurrences by a blank line. print_palindromes() Prints the number of occurrences of Block of text Occurences of palindromes in the text case-insensitive palindrome numbers and palindrome words and letters in the text. The function should print the palindromes sorted alphanumerically with their number of occurrences. Numbers must be printed first, words and letters printed next. main() Driver function that calls all the functions above. None

Inside this module, import random and blackout_utils, and define the following global variable, which you should use whenever appropriate: OPERATIONS = ['^', 'x', '/', '+', '-']For full marks, all the following functions must be part of this module: calculate(tokens): Takes one list of tokens as input corresponding to a mathematical equation. The function will evaluate both sides of the equality and return a list of three tokens: the result of the left-hand side (integer), the equals sign (string), and the result of the right-hand side (integer). The equation may contain any of the operations in the OPERATIONS list, as well as opening and closing parentheses. Your function should evaluate both sides of the equation while respecting order of operations (that is, parentheses, followed by exponentiation, then multiplication and division, and then addition and subtraction). Equations may have multiple sets of parentheses and nested parentheses. The contents of the inner-most nested…
