How to define input in Python?

In Python, we do this using the input() function, which is literally 'input' in English. The input() function receives as a parameter a string that will be shown as an aid to the user, usually informing him what kind of data the program is expecting to receive.

So in an easier way we have that the code is:

def isNumber(x):

   if type(x) == int:

        return True

   else:

        return False

input1 = 122

input2 = '122'

if isNumber(input1):

   print("Integer")

else:

   print("String")

if isNumber(input2):

   print("Integer")

else:

   print("String")

You have been asked to write a program for the Duckie's Obstacle Race. The program calculates the total number of racers, the fastest race time, the slowest race time, and the overall average race time.

Ask user to enter the maximum number of racers allowed for the race
Use repetition structure (loop) to ask the user to enter race times (in minutes)
Exit the loop if the user specifies there are no more times to enter (sentinel value) or if the maximum number of racers allowed has been reached
At a minimum, within the loop, you should keep track of how many race times are entered, the fastest race time and the slowest race time.
After the loop is exited, display how many race times were entered, the fastest race time, the slowest race time and the overall average race time.
Format your output appropriately
Be sure to include all appropriate documentation at the start of the program and within the program body

The race program

The program written in Python, where comments are used to explain each action is as follows:

totalRaceTime = 0; minRaceTime = 0; maxRaceTime = 0; countTimes = 0

#This gets input for the number of race times

#This opens a sentinel controlled loop

while countTimes < numTimes:

   #This gets the race time

   raceTime = int(input("Race time: "))

   if countTimes == 0:

       minRaceTime = raceTime

       maxRaceTime = raceTime

   #This determines the highest race time

   if raceTime > maxRaceTime:

       maxRaceTime = raceTime

   #This determines the leest race time

   if raceTime < minRaceTime:

       minRaceTime = raceTime
