modules in python

• module is a file in python
• lets say we create a file called as utils.py then utils is the module name
• python functions, classes and variables defined in the modules can be imported in other modules.
• A python file can be executed directly python euler3.py then we will be executing the python code and other way is using import

• the case of special variable __name__.
  • This variable will have module name if imported
  • This variable will contain value __main__ if the user executed this python file
