definations if __name__ == '__main__': implementation statements This is block included in modules that contain definations of functions and class types, so that, the implementation statements for testing these definations may be executed on condition that the executing program is the module itself (__name__ == '__main__':). If the module was imported and executed from another program, then the condition will not be satisfied and the implementation statements will be suppressed. **This is wondeful feature of Python that enables nesting of modules without worrying about the danger of local implementation statements in the module getting executed in the importing program. read less

I want to develop website which uses rest-api and Inventory/stock functionality in Python-Django. From where should I start
It seems you want to work on Django Web Framework. The very first pre-requisite for this is that you must know Python Programming. So, I would say learn Python first before embarking on Django Web-Framework.
