Python syntax and semantics. A snippet of Python code with keywords highlighted in bold yellow font. The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers). The Python language has many similarities to Perl, C, and Java ...
Python is a multi-paradigm programming language. Object-oriented programming and structured programming are fully supported, and many of their features support functional programming and aspect-oriented programming (including metaprogramming [ 70] and metaobjects ). [ 71] Many other paradigms are supported via extensions, including design by ...
Graph database. A graph database ( GDB) is a database that uses graph structures for semantic queries with nodes, edges, and properties to represent and store data. [ 1] A key concept of the system is the graph (or edge or relationship). The graph relates the data items in the store to a collection of nodes and edges, the edges representing the ...
Triplestore. A triplestore or RDF store is a purpose-built database for the storage and retrieval of triples [ 1] through semantic queries. A triple is a data entity composed of subject – predicate – object, like "Bob is 35" (i.e., Bob's age measured in years is 35) or "Bob knows Fred". Much like a relational database, information in a ...
A data structure known as a hash table.. In computer science, a data structure is a data organization and storage format that is usually chosen for efficient access to data. [1] [2] [3] More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data, [4] i.e., it is an algebraic structure about data.
palletsprojects .com /p /flask /. Flask is a micro web framework written in Python. It is classified as a microframework because it does not require particular tools or libraries. [ 2] It has no database abstraction layer, form validation, or any other components where pre-existing third-party libraries provide common functions.
PyQt is a Python binding of the cross-platform GUI toolkit Qt, implemented as a Python plug-in.PyQt is free software developed by the British firm Riverbank Computing. It is available under similar terms to Qt versions older than 4.5; this means a variety of licenses including GNU General Public License (GPL) and commercial license, but not the GNU Lesser General Public License (LGPL).

Flow diagram. In computing, serialization (or serialisation) is the process of translating a data structure or object state into a format that can be stored (e.g. files in secondary storage devices, data buffers in primary storage devices) or transmitted (e.g. data streams over computer networks) and reconstructed later (possibly in a different ...
