在单独的.py文件中编写导入模块列表

Question

I have a long list of import modules, something like this:

import x
import y
.
.

How can I write these all imports in one line? I come from C programming and see people doing #include "all_lib.h". Is there a equivalent or better pythonic way of doing this ?

Thanks.

Answer 1

You can put all those imports in one python file, call it all_imports.py , and then import everything from that file using from all_imports import * in your actual Python file.

Example:

File all_imports.py

import math
import collections

File test.py

from all_imports import *

print dir()
print math.pi

Answer 2

您只有一个文件，例如包含所有导入模块的myimports.py，然后将其用作from myimports import *

Answer 3

You can use from all_imports import * . But using names not explicitly named in the module would not be pythonic according to the Style Guide for Python Code (under wildcards).

Answer 4

Actually, you can do

import x, y

But you shouldn't do it according to PEP 8

Answer 5

you can simply do:

import a, b, c, d, e, f, g, h

But take a look at the Style Guide for Python Code which says that you shall put them on separate lines.
