Printing Integers in Hexadecimal Format in Python

Printing integers in hexadecimal format in Python is a simple task that can be accomplished using the built-in hex() function. By following the steps outlined in this post, you can easily print integers in hexadecimal format in Python. Additionally, by using string formatting, you can control the format of the hexadecimal output to suit your needs.

Using the hex() function

The hex() function is a built-in function in Python that converts an integer to a hexadecimal string. The function takes one argument, which is the integer to be converted.

Here’s an example code snippet that demonstrates how to use the hex() function to print an integer in hexadecimal format:

i = 255
print(hex(i))

In this example, the hex() function is used to convert the integer 255 to a hexadecimal string. The resulting string is then printed to the console using the print() function. The output of this code will be:

0xff

As you can see, the hex() function converts the integer 255 to the hexadecimal string 0xff.

Formatting hexadecimal output

The hex() function can also be used in conjunction with string formatting to control the format of the hexadecimal output. Here’s an example code snippet that demonstrates how to use string formatting to format the output of the hex() function:

i = 255
print("The hexadecimal representation of {} is {:x}".format(i, i))

In this example, the format() method is used to format the output of the hex() function. The curly braces {} are used as placeholders for the i variable, which is passed as the second argument to the format() method. The :x format specifier is used to convert the integer to a lowercase hexadecimal string.

The output of this code will be:

The hexadecimal representation of 255 is ff
