Flask was created by Armin Ronacher of Pocoo, an international group of Python enthusiasts formed in 2004. [6] According to Ronacher, the idea was originally an April Fool's joke that was popular enough to make into a serious application. [7] [8] [9] The name is a play on the earlier Bottle framework. [7]
The request has been fulfilled, resulting in the creation of a new resource. [6] 202 Accepted The request has been accepted for processing, but the processing has not been completed. The request might or might not be eventually acted upon, and may be disallowed when processing occurs. 203 Non-Authoritative Information (since HTTP/1.1)
The implementation module, starting with the keyword MODULE, provides the code, and any further constants, types, or variables needed to implement the interface. By default, an implementation module will implement the interface of the same name, but a module may explicitly EXPORT to a module not of the same name. For example, the main program ...
Requests is an HTTP client library for the Python programming language. [2] [3] Requests is one of the most downloaded Python libraries, [2] with over 300 million monthly downloads. [4] It maps the HTTP protocol onto Python's object-oriented semantics. Requests's design has inspired and been copied by HTTP client libraries for other programming ...
A data set (or dataset) is a collection of data. In the case of tabular data, a data set corresponds to one or more database tables, where every column of a table represents a particular variable, and each row corresponds to a given record of the data set in question. The data set lists values for each of the variables, such as for example ...
Instance variables or attributes – data that belongs to individual objects; every object has its own copy of each one. All 4 variables mentioned above (first_name, position etc) are instance variables. Member variables – refers to both the class and instance variables that are defined by a particular class.
Missing not at random (MNAR) (also known as nonignorable nonresponse) is data that is neither MAR nor MCAR (i.e. the value of the variable that's missing is related to the reason it's missing). [5] To extend the previous example, this would occur if men failed to fill in a depression survey because of their level of depression.
In computer science, a set is an abstract data type that can store unique values, without any particular order. It is a computer implementation of the mathematical concept of a finite set . Unlike most other collection types, rather than retrieving a specific element from a set, one typically tests a value for membership in a set.
