For example, file.py, can be considered a module named file.This differs from a package in that a package is a collection of modules in directories that give structure and hierarchy to the modules..

You should start a new line for each instruction to keep the code readable, although separating them with a ; also works.. For example, to import the randint function from the random module and the sqrt function from the math module and then print a result from both functions, you would write: In this, we will import a subdirectory path. PPS Works with subdirectories: import A.B. database manipulation, views, etc.). import import_ipynb In this figure, the module 'top_module.py' is a top-level Python file which imports tools defined in module 'module1', but also has access to tools in 'module2' through 'module1'.
