For example, if you have two draw modules with slighty different names - you may do the following: game. There are some reasons to avoid unnecessary object-orientation.

Writing a module in python what is the main

Python makes educated guesses on whether variables are local or global. Conclusion Creating a module is required for better management of code and reusability. Python also allows you to create your own modules and use them in your programs. Pots Phone. If it is not found, the Python interpreter will search for modu. Modules and Packages In programming, a module is a piece of software that has a specific functionality. Using properly mutable types for things that are mutable in nature and immutable types for things that are fixed in nature helps to clarify the intent of the code. If you want to use a module residing in some other directory, you have some options provided by Python. Some modules are built into the interpreter; these provide access to operations that are not part of the core of the language but are nevertheless built in, either for efficiency or to provide access to operating system primitives such as system calls.

When you import a module named calculation, the interpreter first searches for a built-in module with that name. Python stops searching the local namespace for the variable. Also, the compiled modules are platform-independent, so the same library can be shared among systems with different architectures.

For example, to import the module support. Two very important functions come in handy when exploring modules in Python - the dir and help functions.

python module example

To keep in line with the style guide, keep module names short, lowercase, and be sure to avoid using special symbols like the dot. Easy, here, means that you do not have many constraints and that the module importing model is easy to grasp. However, any namespace cannot have two objects with the exact same name, so the import command may replace an existing object in the namespace.

You can use the functions inside a module by using a dot. The dir function The dir function is used to find out all the names defined in a module. Therefore, Python programmers have more latitude to not use object-orientation, when it is not required by the business model.
