Python uses indentation to define blocks of code instead of curly braces or keywords. If the indentation is not correct, Python raises an IndentationError. In this article, you will learn how to catch and handle IndentationError in Python using various approaches. An IndentationError in Python occurs when the indentation rules ... Read More

A TypeError occurs in Python when we perform an operation on an object of an inappropriate type. For example, adding a string to an integer or calling a non-callable object. In this article, you will learn how to catch and handle TypeError exceptions using different methods in Python. TypeError is ... Read More

In Python, the EnvironmentError occurs when errors related to the system's environment, such as file I/O issues or hardware failures, occur. In the latest Python versions (i.e., 3.3+), this exception is the same as OSError. In this article, you will learn how to catch EnvironmentError (or OSError) to handle system-level ... Read More

LookupError in Python is the base class for errors that occur when a lookup using a key or index fails to find the expected value. This includes exceptions like IndexError and KeyError. If any lookup operation fails, a LookupError or one of its subclasses is raised. In this article, you ... Read More
