Convert hex value into string - Sancho_Pansa - Dec-22-2020 Hello, >>> hex_value = 0xFF >>> string_value = 'hex value is: ' + str(hex_value) >>> string_value 'hex value is: 255'How to get hex value is: FF ? Thanks Sancho RE: Convert hex value into string - jefsummers - Dec-22-2020 This includes the 0x hex_value = 255 hex_value_str = hex(hex_value) print(f'hex value is: {hex_value_str}')
RE: Convert hex value into string - bowlofred - Dec-22-2020 Some options: >>> format(255, "x") 'ff' >>> format(255, "X") 'FF' >>> f"{255:x}" 'ff' >>> f"{255:X}" 'FF' >>> f"{hex(255)}" '0xff' RE: Convert hex value into string - deanhystad - Dec-22-2020 What do you mean by "get hex value is: FF"? Python lets you use hex notation when writing a string literal. x = 0xffAnd 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' RE: Convert hex value into string - Sancho_Pansa - Dec-23-2020 Well ... probably I have to clarify the problem
Sincerely, Sancho RE: Convert hex value into string - bowlofred - Dec-23-2020 Why not just strip off the 0x? If you receive it in that form and send it in that form, you don't actually need to interpret it as a number at all. h = input("Enter the hex value: ") h = h.replace("0x", "") new_string = f"The hex value is {h}" print(new_string)

RE: Convert hex value into string - Sancho_Pansa - Dec-23-2020 I rushed a little bit saying it's Ok. Actually, the problem is not completely resolved: format suppress leading zeros For example 0x00FF is foramtted as FF, but it should be 00FF. Any suggestions ? RE: Convert hex value into string - Sancho_Pansa - Dec-23-2020 Resolved: 'hex value is: ' + '{:04X}'.format(hex_value) |
