# 1. Introduction

Determining the number of digits in a given number is a fundamental task in programming. This can be particularly useful in validating input, determining numerical ranges, or preparing for data storage solutions. Python can accomplish this task with various approaches, and here we'll explore a straightforward method.

The number of digits in a number is the count of individual figures that make up that number. For example, the number 12345 has five digits.

# 2. Program Steps

1. Accept or define a number to analyze.

2. Convert the number to a string to enable easy counting of characters.

3. Count the characters in the string, which corresponds to the number of digits in the original number.

4. Display the count.

# 3. Code Program

``````# Accept or define a number
number = 123456

# Convert the number to a string
number_str = str(number)

# Count the characters in the string
digit_count = len(number_str)

# Display the count of digits
print(f"The number {number} has {digit_count} digits.")
``````

### Output:

```The number 123456 has 6 digits.
```

### Explanation:

1. number is initialized with the integer 123456.

2. number_str is the string representation of number, obtained by calling str(number).

3. digit_count uses the len() function to count the number of characters in number_str.

4. Since number_str is a direct character-by-character representation of number, the length of number_str is equal to the number of digits in number.

5. The print statement then uses an f-string to format and output the result, indicating the number of digits present in the original number, which is 6 for 123456.
