# How to Convert a Number to a Hex String in Python

This pithy article shows you how to turn a number (integer, float) into a hexadecimal value in Python.

## Convert an integer to a hex value

You can use the `hex()` function to convert a given integer to a hex string that starts with the prefix `0x`.

Example:

``````my_int = 2023
my_hex = hex(my_int)
print(my_hex)``````

Output:

``0x7e7``

Using the `format()` function with the `x` specifier is an alternative solution. However, it returns a hex string without the prefix `0x`. You can simply add this prefix with string concatenation if needed.

Example:

``````# convert 2023 to hex without prefix
my_hex = format(2023, 'x')
my_hex = '0x' + my_hex
print(my_hex)``````

Output:

``0x7e7``

## Convert a float to a hex string

In Python, in order to convert a float number to a hex string, the easiest and most convenient way is to use the `float.hex()` method. The resulting hex string has the form `0xh.hhhhp+e`, where `h.hhhh` is the hexadecimal fraction, and `e` is the exponent in decimal.

Example:

``````my_float = 9.999
my_hex = my_float.hex()
print(my_hex)``````

Output:

``0x1.3ff7ced916873p+3``

That’s it. Happy coding & have a nice day. Goodbye!
