Calculate average in python

I’ve made this console application and it works…but only when you enter small numbers in the input like 1 in ‘ifrom’, 2 in ‘step’ and 3 in ‘to’…but when I enter bigger numbers in ‘to’ for example 100 it just do nothing!!! It even doesn’t give me any error!
Thanks!

print("---Average2---"+"\n")

sum=0
average=0
counter=0

while True:
    ifrom=int(input("From: "))
    step=int(input("Step: "))
    to=int(input("To: "))
    while sum<=to:
        sum=ifrom+step
        counter+=1
        if sum==to:
            print("\n"+"The sum is: ",sum)
            average=sum/counter
            print("The average is: ",average,"\n")
            sum=0
            average=0
            counter=0
            break

>Solution :

You can remove the nested while loop by using built-in Python functions like range():

print("---Average2---"+"\n")

s=0
average=0
counter=0

while True:
    ifrom=int(input("From: "))
    step=int(input("Step: "))
    to=int(input("To: "))
    
    l = list(range(ifrom, to, step))
    s = sum(l)
    average = s/len(l)
    print("\n"+"The sum is: ",s)
    print("The average is: ",average,"\n")
    break

Output: Note that the last number of the range to is not inclusive

---Average2---

From: 0
Step: 1
To: 10

The sum is:  45
The average is:  4.5
