It's easy to learn and fun, and its syntax is simple yet elegant. Python is a popular choice for beginners, yet still powerful enough to to back some of the. Python CheatSheet. Basic syntax from the python programming language. Showing Output To User. The print function is used to display or print output.

Each abstract base class specifies a set of virtual subclasses. These classes are then recognized by isinstance and issubclass as subclasses of the ABC, although they are really not. ABC can also manually decide whether or not a specific class is its virtual subclass, usually based on which methods the class has implemented. Splat expands a collection into positional arguments, while splatty-splat expands a dictionary into keyword arguments. Splat combines zero or more positional arguments into a tuple, while splatty-splat combines zero or more keyword arguments into a dictionary. If variable is being assigned to anywhere in the scope, it is regarded as a local variable, unless it is declared as a 'global' or a 'nonlocal'. Decorator that prints function's name every time the function is called. Decorator that caches function's return values. All function's arguments must be hashable. A decorator that accepts arguments and returns a normal decorator that accepts a function. MRO determines the order in which parent classes are traversed when searching for a method or an attribute:. Decorator that automatically generates init , repr and eq special methods. Mechanism that restricts objects to attributes listed in 'slots' and significantly reduces their memory footprint. A duck type is an implicit type that prescribes a set of special methods. Any object that has those methods defined is considered a member of that duck type. Unlike listdir , scandir returns DirEntry objects that cache isfile, isdir and on Windows also stat information, thus significantly increasing the performance of code that requires it. A server-less database engine that stores each database into a separate file. Values are not actually saved in this example because 'conn. Bytes object is an immutable sequence of single bytes. Mutable version is called bytearray. List that can only hold numbers of a predefined type. Available types and their minimum sizes in bytes are listed above. Sizes and byte order are always determined by the system. A thread-safe list with efficient appends and pops from either side. Pronounced "deck". Type is the root class. If only passed an object it returns its type class. Otherwise it creates a new class. Right before a class is created it checks if it has the 'metaclass' attribute defined. If not, it recursively checks if any of his parents has it defined and eventually comes to type. Exception description, stack trace and values of variables are appended automatically. Array manipulation mini-language. It can run up to one hundred times faster than the equivalent Python code. Object that groups together rows of a dataframe based on the value of the passed column.

If any dimensions differ in size, expand the ones that have size 1 by duplicating their elements: 3. If neither non-matching dimension has size 1, raise an error.
