Where You Might See a Python KeyError in the Standard Library

Most of the time, a Python KeyError is raised because a key is not found in a dictionary or a dictionary subclass, such as os.environ. There are also some rare cases in which you might see it raised in Python’s standard library, such as the zipfile module if an item isn’t found in a zip archive.
