Yes, this file is required if you want directory to be treated as a module. The __init__.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path. … Read more
You can add the parent directory to PYTHONPATH, in order to achieve that, you can use OS depending path in the “module search path” which is listed in sys.path. So you can easily add the parent directory like following: import sys sys.path.insert(0, ‘..’) from instance import config Note that the previous code uses a relative … Read more
I suggest putting trivial “launcher” scripts at the top level of your project, and making each of the subproject folders into packages. The modules in the packages can import each other or common code can be factored out into a common package. Here’s what the structure would look like, if we assume the various merger … Read more
Use update for dicts: globals().update(importlib.import_module(‘some.package’).__dict__) Note, that using a_module.__dict__ is not the same as from a_module import *, because all names are “imported”, not only those from __all__ or not starting with _.
It is set to the absolute name of the module as imported. If you imported it as foo.bar, then __name__ is set to ‘foo.bar’. The name is determined in the import.c module, but because that module handles various different types of imports (including zip imports, bytecode-only imports and extension modules) there are several code paths … Read more
there are various approaches to do so, here is just a silly and simple one: main.py “””A silly example – main supplies a parameter “”” import sys,os print os.path.basename(__file__)+”:Push it by: –myModuleParam “+str(123) sys.argv.append(‘–myModuleParam’) sys.argv.append(123) import module print os.path.basename(__file__)+”:Pushed my param:”+str(module.displayMyParam) module.py “””A silly example – module consumes parameter “”” import sys,os displayMyParam = ‘NotYetInitialized’ … Read more
Even if the old python version has been removed, it is possible to use the pip of the current python version with the –path option to list all the modules installed in the previous version. For example, migrating all my user installed python modules from 3.7 to 3.8 pip freeze –path ~/.local/lib/python3.7/site-packages > requirements.txt pip … Read more
I got this problem until I setup nose with sudo: sudo pip install nose
The first argument to parse_args is a list of arguments. By default it’s None which means use sys.argv. So you can arrange your script like this: import argparse as ap def main(raw_args=None): parser = ap.ArgumentParser( description=’Gathers parameters.’) parser.add_argument(‘-f’, metavar=”–file”, type=ap.FileType(‘r’), action=’store’, dest=”file”, required=True, help=’Path to json parameter file’) parser.add_argument(‘-t’, metavar=”–type”, type=str, action=’store’, dest=”type”, required=True, help=’Type … Read more
A few ways. The easy way: Don’t extend the module, extend the classes. exttwitter.py import twitter class Api(twitter.Api): pass # override/add any functions here. Downside : Every class in twitter must be in exttwitter.py, even if it’s just a stub (as above) A harder (possibly un-pythonic) way: Import * from python-twitter into a module that … Read more
