KeyError Raised when a key is not found in a dictionary. KeyboardInterrupt Raised when the user hits the interrupt key (Ctrl+c or delete). MemoryError Raised when an operation runs out of memory. NameError Raised when a variable is not found in the local or global scope. NotImplementedError...
For 2, the correct statement for expected behavior is t = ('one',) or t = 'one', (missing comma) otherwise the interpreter considers t to be a str and iterates over it character by character. () is a special token and denotes empty tuple. In 3, as you might have already figured...
However, this expression doesn’t work as expected, returning expression_2 when expression_1 is falsy. Some Python developers would avoid the syntax of conditional expressions in favor of a regular conditional statement. In any case, this syntax can be handy in some situations because it provides...

Let’s create an extension module calledspam(the favorite food of Monty Python fans...) and let’s say we want to create a Python interface to the C library functionsystem().[1]This function takes a null-terminated character string as argument and returns an integer. We want this function...
Paths may contain wildcard characters such as**(a directory or multiple levels of directories),*(a sequence of zero or more characters), or?(a single character). If no value is provided, the value ofpython.linting.ignorePatterns(if set) will be used. ...
Not every byte holds a valid ASCII character, and not every byte sequence is valid UTF-8 or UTF-16; therefore, when you assume one of these encodings while converting a binary sequence to text, you will get a UnicodeDecodeError if unexpected bytes are found. On the other hand, many legacy...
In the Strings chapter, I talked about the history of character encoding and the creation of Unicode, the “one encoding to rule them all.” I’d love it if I never had to see a gibberish character on a web page again, because all authoring systems stored accurate encoding information, ...
