Convert hex value into string

[deanhystad]

What do you mean by "get hex value is: FF"? Python lets you use hex notation when writing a string literal.

x = 0xff

And you can print an integer using hex notation a number of ways.

print(hex(x))
print(f'{x:x}')
print(f'{x:X}')

Or do you want to "get" a hex value, as in using input() to enter a hex value? Unfortunately I get an error when I try to do this:

x = int(input('Enter a number in hex format '))

Then error is informative "ValueError: invalid literal for int() with base 10: '0xFF'. So I tried this:

x = int(input('Enter a number in hex format '), 16)

This works if I enter 'ff', 'FF', '0xff' or '0xFF'
