Python hex() Method
The hex() method converts an integer number to a lowercase hexadecimal string prefixed with "0x".
If the specified value is not an int object, it has to define an __index__() method that returns an integer.

Use the float.hex() function to convert a float to hexadecimal, as shown below.
Example: hex()
# hex(10.1) # raise an error
print("Hexadecimal of 3.9 is: ", float.hex(10.1)) # valid
Output
0x1.4333333333333p+3
Use the int() function to convert hexadecimal to an integer.
