Python Value Error:Need more than 1 value to unpack why this error

I write this code:

 while(1):
     a,b,c=input().split(" ")
     a=int(a)
     b=int(b)
     c=int(c)
     if(a==0):
         break
     else:
         d=a*b
         c=(d*100)/c
         f=c**(1/2.0)
         print(int(f))

but this error occured:

Traceback (most recent call last): File "Main.py", line 2, in
    a,b,c=input().split(" ")
ValueError: need more than 1 value to unpack
Command exited with non-zero status (1)

please anyone tell me why this error occured and I can I get rid from this error.

your error is explained in the error message:

need more than 1 value to unpack

this means that werever your input function is returning, it does not have (at least) 2 spaces/tabs.

You expect to unpack 3 variables: a,b,c so if there's no split(" "), you can't get 3 values back...

This works...

def input():
  return "one two three"

a,b,c=input().split(" ")
