enviroment: python3.8
directory:
test\ module1\ __init__.py mod1.py module2\ mod2.py main.py 1. I can import a directory without __init__.py , why?
I want to check how exactly init.py work, so I import the module1 and module2 in main.py
# test\main.py from module1 import mod1 from module2 import mod2 In my expectation, line2 should occur error, because I didn't create __init__.py in module2
But both of them can be imported.
Now, I'm confused about how exactly __init__.py work
2. I can't import those package which is imported in __init__.py
I try to import mod1.py in main.py in this way:
# test\main.py import module1 module.mod1.mod1_print() # mod1_print() is a function which is defined in mod1.py So I import mod1.py in test\module1\__init__.py :
# test\module1\__init__.py import mod1 But when I execute main.py I got this error:
D:\>"C:/Program Files/Python38/python.exe" d:/test/main.py Traceback (most recent call last): File "d:/test/main.py", line 2, in <module> import module1 File "d:\test\module1\__init__.py", line 1, in <module> import mod1 ModuleNotFoundError: No module named 'mod1' My question is:
If I want to import mod_print() in this form: module.mod1.mod1_print() , what should I do?
