For Pyhton 3.6

Modular Design: Implement a set of functions called get_data, extract values, and calc.ratios. Function get data should prompt the user to enter a pair of integers in the same line and read the pair as a single string. For example, Enter integer pair (hit Enter to quit): 134 289 This is read as '134 289 This string should be passed into function extract.values, which is designed to return the string as a tuple of two integer values, i.e. extract values ('134 289') should return (134, 289) Finally, this tuple is passed to function calc_ratios which returns the ratio of the two values. For example, calc_ratios ((134,289)) returns 0.46366782006920415 When the second value of the tuple is zero, the ratio is not defined. In this case, the function should return None
