I need help with this programming assignment. I'm confused with the functions get_user_response and validate_response. Any help would be great!

Goal To write a program in Python to test the user's ability to do arithmetic operations on fractions, and award points on correct attempts Description The program will have one or more rounds, depending on whether the user decides to continue or not at the end of each round. During each round, the program will ask the user to enter the numerator and the denominator of the correct answer for an arithmetic operation involving fractions. These fractions, as well as the specific operation itself (one of the following four: addition, subtraction, multiplication, and division) should be generated/chosen randomly. These fractions (operands) will always be positive, however, please note that, the result might not be always positive (Note: You do NOT need to reduce any of the fractions in this program to their lowest terms). The operand fractions should always have a value less or equal to 1 when reduced (which means the numerator of a fraction cannot be greater than the corresponding denominator). The range of values for the numerators of the fractions are determined by the difficulty level chosen by the user (1, 2, or 3) at the beginning of each round. Level 1 restricts the denominators to [1,5], level 2 restricts the denominators to [6,10], and level 3 restricts the denominators to [11,15]. Any other value for the difficulty level entered by the user should be consideredinvalid andthe user should be asked to re- enter the difficulty level. Once a problem (two numerators, two denominators and the arithmetic operation to be performed on them) is generated, the user is shown the problem and asked to enter the numerator and the denominator of the estimated result (if the result is negative, enter a negative numerator and positive denominator). If both of the entered values are correct (matches the correct numerator and denominator), the user gains points
