How to find the number of digits in a given number using Python?
In this program, we have to find the number of digits in an integer given by the user.
User Input: 123, Output: 3
User Input: 1987, Output: 4
Step 1: Take Integer value as input value from the user
Step 2: Divide the number by 10 and convert the quotient into Integer type
Step 3: If quotient is not 0, update count of digit by 1
Step 4: If quotient is 0, stop the countStep 5: STOP
x = int(input("User Input: ")) count_of_digits = 0 while x > 0: x = int(x/10) count_of_digits += 1 print("Number of Digits: ",count_of_digits)
User Input: 123 Number of Digits: 3 User Input: 1987 Number of Digits: 4
When we divide a number by 10 and convert the result into type int, the unit's place digit gets deleted. So, by dividing the result each time by 10 will give us the number of digits in the integer. Once the result becomes 0, the program will exit the loop and we will get the number of digits in the integer.
