How to Skip Unwanted Elements in Python Lists Using dropwhile()

The dropwhile() function from Python's itertools module is used to filter items in an iterable. It continues to drop elements from the iterable as long as the specified condition is true. Once the condition becomes false for an element, dropwhile() stops filtering and returns all subsequent elements, unchanged. This function is especially useful when you want to skip initial elements based on a condition until a change occurs.

This code example demonstrates using dropwhile() to filter out negative numbers from a list of integers. The function stops filtering once it encounters the first non-negative number, showcasing its utility in processing data streams selectively.
