Answer to Question #298382 in Python for Arab

Question

Write a program that has 3 functions: the main function; a function, called getInput(), to

validate the input data; and a function, called findSum(t), to find the summation of even

or odd numbers in a range(0, 10). In particular,

 The getInput() function:

 This function should be called in the main function to validate the data. It asks the

user to input either “e” (even numbers) OR “o” (old numbers). It keeps

asking the user for valid input unit valid input is given, then it returns the valid input

to the main function.

 The findSum(t) function:

 t: a "str" which shows whether you want to sum of all the even or odd numbers in the

range(0, 10)

 If the value of the argument t is 'e', the function should return the sum of all

even natural numbers in the range(0, 10).

 If t has the value 'o', the function should return the sum of all odd natural

numbers in the range(0, 10).

 The main function (): controls the flow of the program and prints the result

Answer 1

def getInput():
    numberType=""
    while numberType!="e" and numberType!="o":
        numberType=input("Input either 'e' (even numbers) OR 'o' (odd numbers): ")
    return numberType
    
def findSum(t):
    result=0
    for i in range(0,10):
        if t=="e":
            if i%2==0:
                result+= i
        if t=="o":
            if i%2==1:
                result+= i
    return result
def main():
    numberType=getInput()
    result=findSum(numberType)
    if numberType=="e":
        print(f"The sum of all the even numbers in the range(0, 10): {result}")        
    if numberType=="o":
        print(f"The sum of all the odd numbers in the range(0, 10): {result}")
main()
