If I have the following file structure in python:
directory1
├── directory2
│ └── file2
└── file1
where directory 2 is a sub directory of directory 1 and assuming that neither is a package, how do I reference the file1 module from file2 assuming I am using sys.path? What import statement would I used in file 2 assuming I have x=1 in file 1 and i would like to print out the value of x in file2?
If directory1 and directory2 are both in sys.path as absolute paths, regardless if one is a subdirectory of the other, then you can import both files with simple statements (I'm assuming they've been named with .py extension at least):
# in file 1:
import file2
# in file 2:
import file1
Then you'd access contents as usual:
# in file 2
import file1
print file1.x
If you need to setup sys.path within file2, then use something like this:
# in file 2
import sys
import os.path
path = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.insert(0,path)
import file1
print file1.x
└── directory1
├── directory2
│ └── file2.py
└── file1.py
$ cat directory1/file1.py
x=1
$ cat directory1/directory2/file2.py
import sys
from os.path import dirname, realpath
sys.path.append(dirname(realpath(__file__)) + '/..')
sys.path.append('..')
from file1 import x
print x
$ python directory1/directory2/file2.py
1
