Python Modules and Packages Successful and Helpful!
Complete Python Bootcamp From Zero to Hero in Python (Basic Modules and Packages)
Contents
1. Creating Modules and Packages
2. Using __name__ and __main__
Create ‘modules_and_packages’ directory:
inside ‘modules_and_packages’ create ‘module.py’ then add this:
def hello(name):
print(‘Hello’, name)
inside ‘modules_and_packages’ create ‘program.py’ then add this:
from basic_codes import hello
hello(‘Your Name’)
Then run program.py to see sample:
# output: Hello Your Name
—————————————————————–
inside ‘modules_and_packages’ create ‘package’ directory
under ‘package’ directory create ‘__init__.py’
under ‘package’ directory create ‘main.py’
inside ‘main.py’ add this code:
def report_main():
print(“Im report_main function inside package > main.py”)
—————————————————————–
under ‘package’ directory create ‘subpackage’ directory
under ‘subpackage’ directory create ‘__init__.py’
under ‘subpackage’ directory create ‘submain.py’
inside ‘submain.py’ add this code:
def report_submain():
print(“Im report_submain function inside subpackage > submain.py”)
—————————————————————–
Back to ‘programs.py’ and add this inside then run:
from package.main import report_main
from package.subpackage.submain import report_submain
report_main()
report_submain()
# output:
Hey Im report_main function inside package > main.py
Hey Im report_submain function inside subpackage > submain.py

Python Modules and Packages Effective Harmoniously!

2. Using __name__ and __main__
Create ‘name_and_main’ directory:
Inside ‘name_and_main’ directory create ‘one.py’ then add this:
def one_func():
print(“one_func() function ran in one.py”)
print(“top-level print inside of one.py”)
if __name__ == “__main__”:
print(“one.py is being run directly”)
else:
print(“one.py is being imported into another module”)
# output:
top-level print inside of one.py
one.py is being run directly
—————————————————————–
Python Modules and Packages – Brilliant Hard-working!
Inside ‘name_and_main’ directory create ‘two.py’ then add this:
import one
print(“top-level in two.py”)
one.one_func()
if __name__ == “__main__”:
print(“two.py is being run directly”)
else:
print(“two.py is being imported into another module”)
#output:
top-level print inside of one.py
one.py is being imported into another module
top-level in two.py
one_func() function ran in one.py
two.py is being run directly
