5. Write a Python program in a file named validTime.py. Include a function named string parameter of the form hh:mm: ss in which these are numeric validTime that takes a values and returns True or False indicating whether or not the time is valid. The number of hours, minutes, and seconds must two digits and use a between 0 and 9). The number of hours must be between 0 and 23, the number of minutes and seconds must be between 0 and 59. Also write a main function that does not take any keyboard input to test your function and call your main function using the leading zero if the number is main__": syntax if name_ -
