Printing values with tabulate in hex

Question

I've been following this answer to print an array as a nice table. This works except that it prints values in decimal. How do I print values in hex? Here is the code:

from tabulate import tabulate

headers = ['array #', 'TX', 'RX']
tx_buffer = [0xCA, 0xFE, 0x80, 0x80, 0x00,
            0x00, 0x00, 0x00, 0x00, 0x00,
            0x00, 0x00, 0x00, 0x00, 0x00,
            0x00, 0x00, 0x00, 0x00, 0x00,
            0x00, 0x00, 0x00, 0x00, 0x00,
            0x00, 0x00, 0x00, 0x00, 0x00,
            0x00, 0x00, 0x00, 0x00, 0x00,
            0x00, 0x00, 0x00, 0x00, 0x00,
            0x00, 0x00, 0x00, 0x00, 0x00,
            0x00, 0x00, 0x00, 0x00, 0x00,
            0x00, 0x00, 0x00, 0x00]

rx_buffer = [0]*54

idx = range(0, 54, 1)
table = zip(idx, tx_buffer, rx_buffer)

print("\n")
print(tabulate(table, headers=headers))
print("\n")

Answer 1

You can use hex or format

tx_buffer=[hex(i) for i in tx_buffer] 
             or

tx_buffer=[format(i, '#x') for i in tx_buffer]

hex(x) :

Convert an integer number to a lowercase hexadecimal string prefixed with “0x”

format(value[, format_spec]) :

Convert a value to a “formatted” representation, as controlled by format_spec

Output:

array #  TX      RX
---------  ----  ----
        0  0XCA     0
        1  0XFE     0
        2  0X80     0
        3  0X80     0
        4  0X0      0
        5  0X0      0
        6  0X0      0
        7  0X0      0
