Write the following Python functions with a variable-length arguments list o Do NOT use Python built-in functions such as max(), sum(), etc. 1. maxVal - returns the largest of arguments (at least one argument needed) .print(maxVal(2)) print(maxVal(2, 1)) print(maxVal(2, 1, 9)) 2. average - returns the average of arguments. If no arguments, return 0. .print(average()) print(average(9)) print(average(1, 2, 3)) print(average(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)) 3. sumOfEvenNum - returns the sum of even numbers of arguments (at least one argument needed) print(sumOfEven Num(1, 2, 3)) print(sumOfEvenNum(1, 2, 3, 4, 5, 6, 7, 8, 9, 10))
