# Check the last digit of a number in Python

In this tutorial, we are going to learn about how to check the last digit of a number in Python with the help of examples.

Note: In Python, strings are the sequence of characters, where the index of the first character is `0`, the second character is `1`, third character is `3` and the last character index `-1`.

Consider, we have a following number:

``pin = 62913``

To check the last digit of a number:

1. Convert the number to a string using the str() Function.

2. Use the square brackets syntax `[]` to access the last character of a string.

3. Convert the result back to a number to get the last digit of the number.

Here is an example:

``````pin = 67683
last_digit_str = str(pin)[-1]

result = int(last_digit_str) # str to int

if result == 3 :
print("last digit is 3")
else:
print("last digit is not 3")``````

Output:

``"last digit is 3"``

In the example above, we first converted the number to a string, so that we can use the square brackets syntax `[]` on it.

You can access the characters of a string, by using the square brackets syntax and specifying an index.

`-1` is the index of a last character in the string. At last we have used the int() function to convert the string to a number.

Note: Negative indexes are used to get data from the end of a string.

You can also shorten the above code in a single line like this:

``````pin = 67683
last_digit = int(str(pin)[-1])

if result == 3 :
print("last digit is 3")
else:
print("last digit is not 3")``````

or You can check the last digit of a number, by dividing the number by 10.

Here is an example:

``````pin = 67683
last_digit = pin % 10

if result == 3 :
print("last digit is 3")
else:
print("last digit is not 3")``````
