>>> numbers = [1, 15, 255]
>>> ''.join('{:02X}'.format(a) for a in numbers)
'010FFF'

Add length parameter to hex - Python Help - Discussions on Python.org
April 23, 2023 - Hey everyone! During my wrok I need to convert int to hex and send it to a server. The problem is that data I send must be paired. To achieve this I write code like this: value_to_send = hex(value)[2:] if len(value_to_send) % 2: value_to_send = '0' + value_to_send My suggestion is to add optional parameter in hex() to automatically pad output with 0 Signature will be changed to def hex(value, length: int | None = None) -> str: pass You would use it like so: >>> hex(13) # 0xd >>> hex...

convert number to length-specified hex string - Raspberry Pi Forums
October 23, 2012 - string = '{:04x}'.format(n)The main advantage of this is that it has a name, so it is easier to find the documentation for it. The disadvantage is that the format string is just as impenetrable if you have not seen it before and, unlike the % format string, is completely python-specific rather than being the same as for sprintf in C, sh, Perl, PHP, Ruby, Octaveโ€ฆ

The 'z' option coerces negative zero floating-point values to positive zero after rounding to the format precision. This option is only valid for floating-point presentation types. Changed in version 3.11: Added the 'z' option (see also PEP 682). The '#' option causes the โ€œalternate formโ€ to be used for the conversion. The alternate form is defined differently for different types. This option is only valid for integer, float and complex types. For integers, when binary, octal, or hexadecimal output is used, this option adds the respective prefix '0b', '0o', '0x', or '0X' to the output value.
