Question

4.2 Exercise # 3: 1 Using for loop, write a python program that reads an integer from the user and prints back the number of the digits in that integer and the sum of them. For example, if the input was 2308, the output would be: Your Integer has 4 digits and their sum is 13. • Hint: take your input as a string and use for loop to get the digits • The following are sample runs of the program • Sample run 1: Enter a positive integer value: 2308 Your integer has 4 digits and their sum is 13 Sample run 2: Enter a positive integer value: 714702 Your integer has 6 digits and their sum is 21 .

Answer 1

To count the number of digits and calculate their sum in a given integer using a Python program, you can follow these steps:

1. Take the input integer from the user.
2. Convert the integer to a string.
3. Initialize variables to keep track of the number of digits and the sum of the digits.
4. Use a for loop to iterate through each character in the string.
5. Check if the character is a digit.
6. If it is a digit, increment the count of digits and add the digit to the sum.
7. Print the results.

For example, if the input integer is 2308, the program will output: Your integer has 4 digits and their sum is 13.

Step-by-step explanation:

To solve this problem, we can follow these steps:

1. Take the input integer from the user.
2. Convert the integer to a string using the str() function.
3. Initialize two variables: num_digits to keep track of the number of digits and sum_digits to calculate the sum of the digits. Set both variables to 0.
4. Use a for loop to iterate through each character in the string.
5. Inside the loop, check if the character is a digit using the isdigit() method.
6. If the character is a digit, increment num_digits by 1 and add the digit to sum_digits by converting it back to an integer using the int() function.
7. After the loop, print the results using formatted strings.

Here is the Python code that implements the above steps:num = input('Enter a positive integer value: ')
