# 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
