hexadecimal world

[DeaD_EyE]

I was very angry about the leading 0x until I have seen binascii and formatting.

In [22]: import binascii                                                        

In [23]: binascii.hexlify(b'Hello World')                                       
Out[23]: b'48656c6c6f20576f726c64'

In [24]: binascii.unhexlify(_)                                                  
Out[24]: b'Hello World'

In [25]: x = 42                                                                 

In [26]: f'{x:x}'                                                               
Out[26]: '2a'

In [27]: f'{x:010x}'                                                            
Out[27]: '000000002a'
