Hi i am looking to implement my own custom file like object for an internal binary format we use at work(i don't really want to go into too much detail because i don't know if i can). I am trying to go for a more pythonic way of doing things since currently we have two functions read/write(each ~4k lines of code) which do everything. However we need more control/finesse hence the fact of me rewriting this stuff.
I looked at the python documentation and they say what methods i need to implement, but don't mention stuff like iter() / etc.
Basically what i would love to do is stuff like this:
output_file_objs = [
open("blah.txt", "w")
open("blah142.txt", "wb")
my_lib.open("internal_file.something", "wb", ignore_something=True)
]
data_to_write = <data>
for f in output_file_objs:
f.write(data_to_write)
So i can mix it in with the others, and basically have a level of transparency. I will add custom methods to it, but thats not a problem.
Is there any sort of good reference regarding writing your own custom file like objects? Like any form of restrictions or special methods (iter). I should implement?
Or is there a good example of one from within the python standard library that i can look at?
