Python Flatten Function Explained

In Python, the flatten function is used to convert multi-dimensional arrays or nested lists into one-dimensional arrays or lists. This function can extract all elements from lists or arrays containing multiple layers of nesting, turning them into a single-layer data structure. This is very useful when dealing with multi-dimensional data, as it allows for easier manipulation and analysis of the data. The flatten function can be implemented using recursion or loops, with the specific approach chosen based on the specific requirements.
