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')
# add prefix
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!
