Python code to calculate the number of digits in a string.Sample Input:Welc0meSample OutputThe number of digits is: 1

Sure! Here's a step-by-step explanation of the Python code to calculate the number of digits in a string:

1. Start by defining a function called count_digits that takes a string as input.
2. Inside the function, initialize a variable called digit_count to 0. This variable will keep track of the number of digits in the string.
3. Use a for loop to iterate over each character in the string.
4. Inside the loop, use the isdigit() method to check if the current character is a digit.
5. If the character is a digit, increment the digit_count variable by 1.
6. After the loop, return the value of digit_count.
7. Outside the function, prompt the user to enter a string and store it in a variable called input_string.
8. Call the count_digits function with input_string as the argument and store the result in a variable called num_digits.
9. Finally, print the result using the formatted string: "The number of digits is: {num_digits}".

Here's the complete code:

def count_digits(string):
    digit_count = 0
    for char in string:
        if char.isdigit():
            digit_count += 1
    return digit_count

input_string = input("Enter a string: ")
num_digits = count_digits(input_string)
print("The number of digits is:", num_digits)

When you run this code and enter a string, it will count the number of digits in the string and display the result.
