In this tutorial, we will learn how to get the second digit of a number in Python.

Python has a rich ecosystem of built-in functions and libraries which makes it easy to perform several operations on numbers.

We will use Python’s built-in functions to get the second digit of a number.

### Step 1: Understanding the concepts of integer and string

To get the second digit of a number, we will first need to understand the difference between an integer and a string. An integer is a whole number while a string is a sequence of characters. In Python, you can convert an integer to a string using the **str()** function and a string to an integer using the **int()** function.

### Step 2: Convert the number to a string

To get the second digit of a number, we must first convert the number to a string. This way, we can access individual digits using indexing. Here’s how you can convert an integer to a string:

1 2 |
number = 12345 number_string = str(number) |

### Step 3: Get the second digit using indexing

Once you have converted the number to a string, you can get the second digit using indexing. In Python, indexing starts from 0. So, to get the second digit, we will use index 1.

1 |
second_digit = number_string[1] |

### Step 4: Convert the second digit back to an integer

After getting the second digit as a string, we can convert it back to an integer using the **int()** function:

1 |
second_digit_integer = int(second_digit) |

Now, let’s combine all the steps above to create a function that returns the second digit of a number.

1 2 3 4 5 6 7 8 |
def get_second_digit(number: int) -> int: number_string = str(number) if len(number_string) < 2: return None second_digit = number_string[1] return int(second_digit) |

### Step 5: Test the function

Now, let’s test the function with a few examples:

1 2 |
print(get_second_digit(56789)) print(get_second_digit(1)) |

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
def get_second_digit(number: int) -> int: number_string = str(number) if len(number_string) < 2: return None second_digit = number_string[1] return int(second_digit) number = 12345 second_digit = get_second_digit(number) print(f"The second digit of {number} is {second_digit}") number = 5678 second_digit = get_second_digit(number) print(f"The second digit of {number} is {second_digit}") number = 9 second_digit = get_second_digit(number) print(f"The second digit of {number} is {second_digit}") |

## Output:

The second digit of 12345 is 2 The second digit of 5678 is 6 The second digit of 9 is None

## Conclusion

In this tutorial, we have learned how to get the second digit of a number in Python using the built-in functions for converting integers to strings and vice versa. This is a simple yet powerful technique you can use when you need to manipulate digits in a number.
