Python int to hex string without 0x

How To Get Hex Representation Without 0x In Python

To get hex representation without 0x in Python, you can use the hex() function combined with the strip() function or other ways. Let’s learn more about it with the explanation and examples below.

Get Hex Representation Without 0x In Python

You can use a formatted String literal or the hex() function combined with the strip() function or format the String literal to get the hex representation without 0x in Python.

Use a hex() function combined with the strip() function

In this solution, we will use the hex() function first, and it will return a String as a hex representation of an integer. But this result will have ‘0x’ in the prefix. So, we will use the strip() function to remove ‘0x’ in the prefix. Then, the last result will be the hex representation without 0x.

Look at the example below to learn more about this solution.

def hexRepresentation(num=int()): # Convert the decimal value to the hex value by the hex() function hexValue = hex(num) # Remove '0x' in the prefix by the strip() function result = hexValue.strip('0x') return result # Try this function print(hexRepresentation(2002))

Formatting the String literal

In this solution, we will convert the integer value to a String representing the hex value without 0x with the format: f’’.

Look at the example below to learn more about this solution.

def hexRepresentation(num=int()): # Format String literal result = f'' return result # Try this function print(hexRepresentation(2002))

Get hex representation without 0x with the list of integers

To get the hex representation without 0x with the list of integers, you simply only need to use one of two previous solutions and combine the result.

Look at the example below.

numList = [6, 88, 6868, 8888, 6666] # Get hex representation without 0x with the 'numList' res = ':'.join(f'' for value in numList) print(res)

Get hex representation without 0x with the String

To get the hex representation without 0x with the String, you can do the same way as getting the hex representation without 0x with the list of integers.

Look at the example below.

name = 'LearnShareIT' # Get hex representation without 0x with this String res = ':'.join(f'' for value in name) print(res)

Summary

We have shown you some ways to get hex representation without 0x in Python. To do that, you can use the hex() function combined with the strip() function or format the String literal. But I think you should do that by formatting the String literal because this method can get not only the hex value but also the binary value, the octal value, etc.

Print hex without 0x in Python

A hex or a hexadecimal string is one of the few forms of data types provided by Python for storing and representing data. A hex string is generally represented with a prefix of 0x . However, we can get rid of this 0x and print just the original hex value.

This tutorial focuses on and demonstrates the several ways available to print hex without 0x in Python.

How to print hex without 0x in Python?

There are several different ways to print hex without 0x in Python, some of the most common ones are described thoroughly in this article below.

There are several ways to convert a data type to hex representation, with most of them providing a direct way to print the hex representation without the 0x prefix. Moreover, the other functions that do not provide a way directly can also be tweaked.

As an example in this tutorial, we will take a variable of the data type int and represent the data stored in it in the hex format without the use of the 0x prefix.

Using slicing along with the hex() function

A concept that is highly effective in this case is string slicing. It is a way to get a sub-string from any given string by slicing it either from the beginning or from the end.

After utilizing the hex() function on the given int value, the obtained hexadecimal or simply hex string can be sliced to remove the 0x prefix while utilizing the print command.

The following code uses slicing along with the hex() function to print hex without 0x in Python.

Python Print Hex Without ‘0x’

If you print a hexadecimal number, Python uses the prefix ‘0x’ to indicate that it’s a number in the hexadecimal system and not in the decimal system like normal integers.

However, if you already know that the output numbers are hexadecimal, you don’t necessarily need the ‘0x’ prefix.

How to print hex numbers without the ‘0x’ prefix?

Method 1: Slicing

To skip the prefix, use slicing and start with index 2 on the hexadecimal string. For example, to skip the prefix ‘0x’ on the result of x = hex(42) =’0x2a’ , use the slicing operation x[2:] that results in just the hexadecimal number ‘2a’ without the prefix ‘0x’ .

x = hex(42) print(x) # 0x2a print(x[2:]) # 2a

Python Int to Hex | String Formatting

💬 Question: How to use Python’s string formatting capabilities — f-strings, percentage operator, format() , string.format() — to convert an integer to a hexadecimal string?

Lowercase Solution without ‘0x’ Prefix

You can convert an integer my_int to a simple lowercase hex string without ‘0x’ prefix by using any of the four string formatting variants—all based on the hexadecimal string formatting symbol x :

Here are those four ways exemplified converting the integer 255 to the hex string ‘ff’ :

>>> my_int = 255 >>> f'' 'ff' >>> '%x'%my_int 'ff' >>> ''.format(my_int) 'ff' >>> format(my_int, 'x') 'ff'

Lowercase Solution with ‘0x’ Prefix

You can convert an integer my_int to a simple lowercase hex string with ‘0x’ prefix by using any of the four string formatting variants—all based on the hexadecimal string formatting symbol x :

Here are those four ways exemplified converting the integer 255 to the hex string ‘0xff’ :

>>> my_int = 255 >>> f'0x' '0xff' >>> '0x%x'%my_int '0xff' >>> '0x'.format(my_int) '0xff' >>> '0x' + format(my_int, 'x') '0xff'

Uppercase Solution without ‘0x’ Prefix

You can convert an integer my_int to a simple uppercase hex string without ‘0x’ prefix by using any of the four string formatting variants—all based on the uppercase heXadecimal string formatting symbol X :

Here are those four ways exemplified converting the integer 255 to the hex string ‘FF’ :

>>> my_int = 255 >>> f'' 'FF' >>> '%X'%my_int 'FF' >>> ''.format(my_int) 'FF' >>> format(my_int, 'X') 'FF'

Uppercase Solution with ‘0x’ Prefix

You can convert an integer my_int to a simple uppercase hex string with ‘0x’ prefix by using any of the four string formatting variants—all based on the uppercase heXadecimal string formatting symbol X :

Here are those four ways exemplified converting the integer 255 to the hex string ‘0xFF’ :

>>> my_int = 255 >>> f'0x' '0xFF' >>> '0x%X'%my_int '0xFF' >>> '0x'.format(my_int) '0xFF' >>> '0x' + format(my_int, 'X') '0xFF'

Fixed-Width Hex String with ‘0’ Padding

You can use the format specifer 02X to convert an integer to a fixed-width hex string with 2 positions, and filling the remaining positions with ‘0’ symbols from the left. For example, the format specifier 03x creates a hex string of width 3 .

Here’s how that works for f-strings:

Analogously, the same format specifier can be applied to all other string formatting capabilities such as format() , string.format() , and percentage operator:

>>> '0x' + format(my_int, '04X') '0x00FF' >>> '0x'.format(my_int) '0x00FF' >>> '0x%04X'%my_int '0x00FF' >>> f'0x' '0x00FF'

This creates an uppercase, fixed-width hex string with 4 positions and padded with 0 s from the left.
