Module import and exception handling in python

Creating an environment for importing Python modules

  1. Make a Derrek Lee package in the main folder
  2. Create a directory folder and files in the directory package. Be sure to create init.py. Because Python recognizes this file and calls the module
  3. Make utils.py in it Create two types of files, a.py b.py, in 4 and 3. To call a function defined later
  4. Next, create another directory folder in the directory package.
  5. Similarly, create init.py. Exception handling is to handle errors even if old packages or new packages are mixed.

Code that calls the module

from directly_package.directlyfolder1 import a.py　//a.py is in directly folder1
from directly_package.directlyfolder2 import b.py
print(folder1.function()) //Function execution
print(folder2.function())

Below is the contents of the files in the directory folder and the path specification. It is necessary to change the path specification depending on the conditions.

Example of module path specification code

from directly_package.directly folder import utils　//Absolute path
def x(): //Any function definition x
return'x'
def y():Let y be the definition of any function
    return utils.z('y')　//utils.The def defined in py.Described in return utils as z

Exception handling example

try:
    from directly_package import utils
except ImportError:
    from directly_package import utils
utils.any_function('word')

To try tomorrow

Create setup.py and try to create your own library.
