Complete the zero_extend_number() function that takes two parameters: • The integer parameter number which represents the number that needs to be zero-extended • The integer parameter length which represents the length of the number string that the function needs to return. The function returns a string representation of the parameter number with the length specified by the parameter length. If the number of digits in number is less than the length, then the function will need to zero-extend number by appending the required number of zeroes to the front of it. You can assume that the parameter length will always be greater than or equal to the number of digits in number. Some examples of the function being used are shown below: For example: Test Result print(zero_extend_number (1, 5)) 00001 print(zero_extend_number(10, 4)) 0010 Answer: (penalty regime: 0 %) Reset answer 1 v|def zero_extend_number(number, length):
