It is initialized to a default path taken from the environment variable

问题 Good afternoon. I am writing a small to medium-sized python program for my job. The task requires me to use the Excel libraries xlwt and xlrd , as well as a library for querying Oracle databases, called cx_Oracle . I am developing the project through a version control system, namely CVS. I was wondering what is the standard way to organize third-party libraries around a python project. Should the libraries xlwt, xlrd, and cx_Oracle be stored in a directory such as /usr/local/lib/python, which

python calling a module that uses argparser

由 ぐ巨炮叔叔 提交于 2019-12-06 19:08:02
问题 This is probably a silly question, but I have a python script that current takes in a bunch of arguements using argparser and I would like to load this script as a module in another python script, which is fine. But I am not sure how to call the module as no function is defined; can I still call it the same way I do if I was just invoking it from cmd? Here is the child script: import argparse as ap from subprocess import Popen, PIPE parser = ap.ArgumentParser( description='Gathers parameters.

问题 In my Django project, the following line throws an ImportError: "No module named elementtree". from elementtree import ElementTree However, the module is installed (ie, I can run an interactive python shell, and type that exact line without any ImportError), and the directory containing the module is on the PYTHONPATH. But when I access any page in a browser, it somehow can't find the module, and throws the ImportError. What could be causing this? 回答1: Can you import elementtree within the
