Use a Module. Now we can use the module we just created, by using the import statement: Example. Import the module named mymodule, and call the greeting function: import mymodule. mymodule.greeting ("Jonathan") Run Example » Note: When using a function from a module, use the syntax: module_name.function_name.

We can import the definitions inside a module to another module or the interactive interpreter in Python. We use the import keyword to do this. To import our previously defined module example, we type the following in the Python prompt. This does not import the names of the functions defined in example directly in the current symbol table. It only ...
The Python standard library contains well over 200modules. We can import a module according to our needs. Suppose we want to get the value of pi, first we import the math module and use math.pi. For example, Output
In Python, we can also import a module by renaming it. For example, Here, We have renamed the math module as m. This can save us typing time in some cases. Note that the name math is not recognized in our scope. Hence, math.pi is invalid, and m.piis the correct implementation.
We can import specific names from a module without importing the module as a whole. For example, Here, we imported only the pi attribute from the mathmodule.
In Python, we can import all names(definitions) from a module using the following construct: Here, we have imported all the definitions from the math module. This includes all names visible in our scope except those beginning with an underscore(private definitions). Importing everything with the asterisk (*) symbol is not a good programming practic...
In Python, we can use the dir()function to list all the function names in a module. For example, earlier we have defined a function add() in the module example. We can use dir in examplemodule in the following way: Here, we can see a sorted list of names (along with add). All other names that begin with an underscore are default Python attributes a...
Dec 29, 2019 · In Python, modules are self-contained files with reusable code units like functions, classes, and variables. Importing local modules allows for organizing the codebase effectively, enhance maintainability, and enhances code reuse. In this article, we will understand how to import local modules with Python. Understanding Modules and PackagesPython M
