[英]How do I import all functions from a package in python?
I have a directory as such: 我有一个目录:
python_scripts/
test.py
simupy/
__init__.py
info.py
blk.py
'blk.py' and 'info.py are modules that contains several functions, one of which is the function 'blk_func(para)'. 'blk.py'和'info.py是包含多个函数的模块,其中一个是函数'blk_func(para)'。
Within '__init__.py' I have included the following code: 在'__init__.py'中我包含以下代码:
import os
dir_path = os.path.dirname(os.path.realpath(__file__))
file_lst = os.listdir(dir_path)
filename_lst = list(filter(lambda x: x[-3:]=='.py', file_lst))
filename_lst = list(map(lambda x: x[:-3], filename_lst))
filename_lst.remove('__init__')
__all__ = filename_lst.copy()
I would like to access the function 'blk_func(para)', as well as all other functions inside the package, within 'test.py'. 我想在'test.py'中访问函数'blk_func(para)',以及包内的所有其他函数。 Thus I import the package by putting the following line of code in 'test.py':
因此,我通过在'test.py'中放入以下代码行来导入包:
from simupy import*
However, inorder to use the function, I still have to do the following: 但是,为了使用该功能,我仍然需要执行以下操作:
value = blk.blk_func(val_param)
How do I import the package simupy, such that I can directly access the function in 'test.py' by just calling the function name? 如何导入软件包simupy,这样我只需调用函数名即可直接访问'test.py'中的函数? ie
即
value = blk_func(val_para)
Pretty easy 满容易
__init__.py
: __init__.py
:
from simupy.blk import *
from simupy.info import *
Btw, just my two cents but it looks like you want to import your package's functions in __init__.py
but perform actions in __main__.py
. 顺便说一句,只是我的两分钱,但看起来你想要在
__init__.py
导入你的包的功能,但是在__main__.py
执行操作。
Like 喜欢
__init__.py
: __init__.py
:
from simupy.blk import *
from simupy.info import *
__main__.py
: __main__.py
:
from simupy import *
# your code
dir_path = ....
It's the most pythonic way to do. 这是最诡计多端的方式。 After that you will be able to:
之后,您将能够:
python -m simupy
python -m simupy
import simupy; print(simupy.bar())
import simupy; print(simupy.bar())
import simupy; print(simupy.bar())
from simupy.info import bar
. from simupy.info import bar
。 For me it's part of the beauty of Python.. 对我而言,它是Python之美的一部分..
