    Path objects also override the / operator to join paths

    This is both cool and gross… gives me C++ vibes (operator overloading abuse).

      A great joy when working with people on a combination of Windows/MacOS/Linux.

      Hell, even great when your laptop is windows and desktop (or even raspberry pi) is Linux

      Scapy is another library where they redefined / to layer packets, such that you can write:

      IP(dst="172.23.34.45") / UDP() / DNS(…)
      

      Then Scapy has magic so that on serialisation, the UDP layer knows defaults to dport=53 if the upper layer is DNS, and it can access the lower layer to compute its checksum.

      And don’t forget that strings have a custom % (as in modulo) operator for formatting:

      "Hello %s" %(username)
      

      Of course in modern Python, f-strings will almost always be more convenient

      They could have chosen a better operator. But the functionality is fantastic. Makes working with paths so much easier. And you can even use slashes on windows paths.

        It makes the code so much more clean and readable since you’re dropping multiple levels of brackets , for example

        os.path.join( a, b, os.path.dirname(c))

        Becomes

        a / b / c.parent

        I really like it

      Don’t forget about the helper functions mypath.read_text() and mypath.write_text(content)

      Today I realised, we all prefer semantics matching oriental language semantics.
      English: Open my path.
      Same sentence in Hindi semantics would be: My path open.
