Creating a Module in Python
- Module have the __name__ variable set to the module name.
- When a python is called as a script, the __name__ is set to "__main__". This lets you create modules that can also be executed as scripts using the following:
def add(x,y):
return x+y
if __name__ = "__main__"
print(add(1,2)) Importing Modules
- To make use of the functions in a module, you'll need to import the module with an import statement.
- An import statement is made up of the import keyword along with the name of the module.
- In a Python file, this will be declared at the top of the code, under any shebang lines or general comments.
Various possibilties of import:
- import modulename
- import module1,module2,module3
- import module1 as m
- import module1 as m1,module2 as m2,module3
- from module import member
- from module import member1,member2,memebr3
- from module import memeber1 as x
- from module import *
