Master Python Hex Conversion: Convert Integers to Hexadecimal Strings

Want to learn how to convert different number formats to hexadecimal strings in Python? The hex() function is your answer. This guide provides clear examples and practical use cases to master Python hex conversion. Discover how to use this built-in function effectively.

What is Python hex()?

The Python hex() function converts an integer to its lowercase hexadecimal representation, prefixed with "0x". It's a simple yet powerful tool for working with different number bases in Python. You can easily convert decimal, binary, and octal numbers to hex strings.

• Effortlessly convert integers to hexadecimal strings.
• Understand the basic syntax and usage.
• Explore advanced applications with custom objects.

Basic Examples of Python hex()

Let's dive into some straightforward examples to illustrate how the hex() function works. These examples cover decimal, binary, octal, and hexadecimal inputs.

print(hex(255))   # Decimal
print(hex(0b111))  # Binary
print(hex(0o77))   # Octal
print(hex(0XFF))  # Hexadecimal

The output will be:

0xff
0x7
0x3f
0xff

As demonstrated, the hex() function automatically converts the input integer, regardless of its original base, into a hexadecimal string format. This makes it invaluable for tasks like converting binary to hexadecimal and octal to hexadecimal within Python.

Using Python hex() with Objects

Did you know you can use hex() with custom objects? To do this, your class needs to define the __index__() method, which should return an integer.

class Data:
    id = 0

    def __index__(self):
        print('__index__ function called')
        return self.id

d = Data()
d.id = 100

print(hex(d))

The output is:

__index__ function called
0x64

• Define the __index__() method in your class.
• Return an integer from this method.
• Use hex() to get the hexadecimal representation of your object.
