We can convert integer number to string hex and transfer string write to the file. Example we can transfer to bytearray

Function to convert decimal to hexadecimal

Just pass the number you want to concert to the hex() method and you'll get back the value in base16 (hexadecimal).

This is and example :

def decimal_to_hexadecimal(dec):
    first_v = str(dec)[0]
    decimal = int(dec)
    if first_v == '-': 
        hex_dec = hex(decimal)[3:]
    else:
        hex_dec = hex(decimal)[2:]
    return hex_dec

result = decimal_to_hexadecimal(2325552)

print('result : ', result)

Output

result : 237c30

Use hex() the Built-in Functions to convert an integer number to a lowercase hexadecimal string prefixed with “0x”

>>> hex(2325552)
'0x237c30'

If you want to remove the 0x prefix you the following code

>>> hex(2325552)[2:]
'237c30'

To avoid the error in case of a negative number use the function described in this answer
