问题 I have a program that I wrote that is creating and maintaining an array and I have another module that I wrote that has functions to manipulate the array. Is it possible to call every function in the imported module without having to hard code every function call? Meaning something like this: #Some way I don't know of to get a list of function objects listOfFunctions = module.getAllFunctions() for function in listOfFunctions: array.function() I want to do this so I don't have to update my

问题 I have a setup.py file like this (not in pwd, not in Python path, a random file somewhere): import ext_modules config = { 'name': 'mesos.executor', 'version': '1.4.1', 'description': 'Mesos native executor driver implementation', 'author': 'Apache Mesos', 'author_email': 'dev@mesos.apache.org', 'url': 'http://pypi.python.org/pypi/mesos.executor', 'namespace_packages': [ 'mesos' ], 'packages': [ 'mesos', 'mesos.executor' ], 'package_dir': { '': 'src' }, 'install_requires': [ 'mesos.interface =

问题 Often when I am using the IDLE shell I import the pickle module. Is it possible to make it automatically import pickle when I start it? 回答1: You can use the -c or - r argument: From idle -h : -c cmd run the command in a shell, or -r file run script from file For example: idle -c 'import pickle, sys' Or: idle -r ~/my_startup.py Where my_startup.py might contain: import pickle, sys You can either create a shell alias to always use this, or create a separate script; the procedure for this

问题 I have an error with import geopandas, fiona.

问题 I apologize for not being able to phrase my question more easily. I am writing a large package that makes extensive use of pandas in almost every function. My first instinct, naturally, was to create an __init__.py as import pandas # then import my own submodules and other things And then, every time I use pandas in a function, call it from the submodules as from . import pandas as pd or from .. import pandas , or something like that. However, if I do this, when I load my package, pandas

问题 Is there any performance difference between from package import * and import package ? 回答1: No, the difference is not a question of performance. In both cases, the entire module must be parsed, and any module-level code will be executed. The only difference is in namespaces: in the first, all the names in the imported module will become names in the current module; in the second, only the package name is defined in the current module. That said, there's very rarely a good reason to use from

问题 It is a similar situation I'd encountered several months ago using pylint prior to pylance: My python 3.9x - script (using VS Code on Lubuntu 20.04 LTS ) starts with the following import of custom "tools": import sys sys.path.append( '/home/andylu/Dokumente/Allgemeines_material/Sonstiges/Programming/Python/Scripts/' ) import General.Misc.general_tools as tools Now, Pylance states Import "General.Misc.general_tools" could not be resolvedPylance (reportMissingImports) even though when executing
