Calculating a Running Total

Answer 1

What is sentinel in python.

sentinel is value which we use to stop the loop
like reading numbers from the user untill he enteres -1
so here -1 is sentinel

Running total is reading values from user and adding to sum

Exampl:

n=int(input("Enter number (-1 to exit): "))
total = n
print("Total: ",total)
while(n!=-1):
        n=int(input("Enter number (-1 to exit): "))
        total+=n
        print("Total: ",total)
