Can someone explain to me the code below. I need to understand what line 2 and line 5 mean when we count digits of a number (ex. 100).
def Counting(Number): Count = 0 while(Number > 0): Number = Number // 10 Count = Count + 1 print("Number of Digits in a Given Number:", Count) Counting(100)
is the variable used to store the number of digits in Number.
while (Number > 0):
this line continues looping until the Number is 0. In other words it loops while Number is a positive integer.
Number = Number // 10
floor division of Number by 10. When you divide a number by 10, you are “removing” its last digit. For example, in the case of 100, it would be
100 // 10 = 10
or in the case of 12345,
12345 // 10 = 1234
this effectively reduces the number of digits by one.
Count = Count + 1
increments Count, as we have removed one digit from Number.
