Python - Get the first digit of a number
In this tutorial, we are going to learn about how to get the first digit of a number in Python with the help of examples.
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
Consider, we have a following number:
pin = 67683
To get the first digit of a number:
Convert the number to a string using the str() Function.
Use the square brackets syntax
to access the first character of a string.
Convert the result back to a number to get the first digit of the number.
Here is an example:
pin = 67683 first_digit_str = str(pin) result = int(first_digit_str) # str to int print(result)
In the example above, first we converted the number to a string, so 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.
0 is the index of a first character in the string. At last we have used the int() function to convert the string to a number.
You can also shorten the above code in a single line like this:
pin = 67683 first_digit = int(str(pin)) print(first_digit)
