   I tried also on docker, with the same result:

   docker run -ti python bash
   echo "import copy" >test.py
   pip install transcrypt
   transcrypt -b test.py

   Hi,

   Unfortunately the 'copy' standard library is not yet supported by Transcrypt.

   TS mostly relies on JS libs:

   http://sterlicht.alwaysdata.net/transcrypt.org/docs/html/what_why.html#the-ecosystem-different-batteries

   We strive to make a limited number of standard libs available, to ease the transition from CPython.

   Currently the following standard modules are available for Transcrypt: math, cmath, re, itertools, time, random (most important functions only), logging, warnings, turtle. There's also a port of a small part of Numpy called Numscrypt, available separately from PyPi.

   Kind regards
   Jacques

   Ok, thanks.
   do you plan to support the "collections" library?

   There were no plans in that direction, but actually that may be a useful one to support.
   In general for libraries we rely on third party contributions.

   @JdeH I'm interested in a port of the collections module too. Where's a good place to discuss the design of it?

    Revisiting this. I know copy is not supported yet, but the message I get is slightly different so I wanted to add to this thread:

    I'm trying to use deepcopy from the built-in copy module copy.deepcopy(), but Transcrypt complains that it can't find PyStringMap when trying to import it
    import copy

    In the mean time I've had some luck with using the lodash.clonedeep() JS library, but it seems to return dictionaries that have to be run through Python dict() to be valid.

    After getting a bit more experience with Transcrypt and re-reading this, I realized my previous post was already answered in that the Python copy library itself is not implemented.

    Related to this though, I see there are copy and deepcopy functions that end up in the Transcrypt JS runtime module. However that deepcopy function does not appear to actually deep copy JavaScript objects. I have worked around this issue by using a JS library (both deepcopy and lodash.cloneDeep work), but was wondering what the relationship of the deepcopy in the Transcrypt runtime is to the Python copy.deepcopy function, and if so are there known limitations of that one? Or am I just misunderstanding something?

    copy module with copy and deepcopy is currently added in dev_3.9.3 branch to be released in v3.9.3
    Need to do a bit more testing on it before releasing.
