Making our way through our in-depth Python Exception Handling series, today we’ll be getting into the UnboundLocalError. An UnboundLocalError is raised when a local variable is referenced before it has been assigned. This error is a subclass of the Python NameError we explored in another recent article. Throughout the remainder… continue reading →

Our journey continues through our detailed Python Exception Handling series with a deep look at the NameError found in Python. Just as with many other programming languages, Python source code (typically found in .py files) is initially compiled into bytecode, which is a low level representation of source code that… continue reading →

Continuing along through our in-depth Python Exception Handling series, today we’ll dig into Python’s MemoryError. As with all programming languages, Python includes a fallback exception for when the interpreter completely runs out of memory and must abort current execution. In these (hopefully rare) instances, Python raises a MemoryError, giving the… continue reading →

Today, as we make our way through our detailed Python Exception Handling series, we’ll be looking into the KeyError, which is the close sibling of the IndexError we looked at last week. Whereas the IndexError is raised when trying to access an invalid index within a list, the KeyError is… continue reading →

Moving right along through our in-depth Python Exception Handling series, today we’ll be going over the IndexError, in all its glory. The IndexError is one of the more basic and common exceptions found in Python, as it is raised whenever attempting to access an index that is outside the bounds… continue reading →

Making our way through our detailed Python Exception Handling series we arrive at the ImportError, along with its single child subclass of ModuleNotFoundError. The ImportError is raised when an import statement has trouble successfully importing the specified module. Typically, such a problem is due to an invalid or incorrect path,… continue reading →

Moving along through our in-depth Python Exception Handling series, today we’ll be going over the EOFError. The EOFError is raised by Python in a handful of specific scenarios: When the input() function is interrupted in both Python 2.7 and Python 3.6+, or when input() reaches the end of a file… continue reading →

Moving along through our in-depth Python Exception Handling series, today we’ll be going over the SyntaxError. As with (probably?) every other programming language ever created, a SyntaxError is an indication that there is a syntactic error in the code, which causes the parser or compiler or executor to be unable… continue reading →

Making our way through our detailed Python Exception Handling series, next up on the docket is the BufferError. The BufferError occurs when a problem arises while working with any sort of memory buffer within Python. Specifically, classes like memoryview and BytesIO tend to raise these error types when something goes… continue reading →
