Learn how to use Python's if __name__ == "__main__" idiom to control code execution. Discover its purpose, mechanics, best practices, and when to use or avoid it. This tutorial explores its role in managing script behavior and module imports for clean an
Discover the functionality and purpose of the 'do' statement in Python programming. Learn how it can be utilized effectively in your code.
However, now when we runmodulesModified.pywhere we importcube(num)function fromcubesModified.py, it only executes the code from ourmodulesModified.pyas shown in Figure 15, and the output is 1000 because the value stored in the__name__variable in cubesModified and not__main__. Figure 13 #...
Python arrays are one of the most utilized data structures that are generally used to store multiple values of the same type in a contiguous memory location. These Python arrays simply provide efficient storage and faster operations for any numerical data. While Python does not have any built-in...
What does Python's'if name equals main'construct do? Python'sif __name__ == "__main__":construct enables a single Python file to not only support reusable code and functions, but also contain executable code that will not explicitly run when a module is imported. ...
When we import a module in Python, several things happen underneath the hood. Here's a brief overview of the steps that occur: 1. The interpreter checks whether the module has already been imported. If it has, the interpreter uses the existing module object rather than loading the module ag...
in the same line, the Python interpreter creates a new object, then references the second variable at the same time. If you do it on separate lines, it doesn't "know" that there's already "wtf!" as an object (because "wtf!" is not implicitly interned as per the facts mentioned abov...
Learn about __init__.py in Python, its purpose, and how it helps in organizing Python packages.
