"Python is object-oriented, it's easy to read, and makes complex tasks simple. It's a Rapid Application Development (RAD) programme, and I often use it as a scripting language. It's an interpreted language, dramatically typed, and its functions are first-class objects. You can use any text editor to write Python.  Python uses third-party modules, is compatible with all major operating systems, and dynamically uses variables. Other reasons it's popular are its outstanding library, it's ability to support big data, and that it can expedite test-driven development."

 "Python dates back to the early 1990s. Guido van Rossum created the language and named it after his favourite British comedy group at the time, Monty Python. He wrote the programme while working at a research facility in the Netherlands. It was a successor to the ABC language and interfaced with amoeba working framework, and took inspiration from Module 3. Worldwide Python users, sometimes called PUGs, hold conferences on every continent except for Antarctica. I actually attended one of those conferences in Alberta last year and found it very informative.

"It's used by the International Space Station's Robonaut 2, in particle physics labouratories, astronomy, cinema special effects, such as in Star Wars, and to build games. It's used in the music and video industries, operation systems, even in your doorbell. I've used Python for web applications, big data, and scientific modelling."

 "Default modules include email, which is parsed and generated by Python. Other default modules are XML support, string, and databases."  

"You convert a Python object into a string through the pickle module, while unpickling does the opposite. Pickling puts the string into a file, and unpickling retrieves stored strings, turning it back into an object." 

"A popular trend in building mobile apps is Python's blockchain. Python was used to build the world's biggest data exchange, BurstIQ. The tech trend of machine learning is another application because Python has the advantage of numerous libraries, such as Pandas and Scikit. Other apps include Netflix, Uber, Spotify, Pinterest, and Reddit. It's also used in dropbox, social media apps like Instagram, and in video games like Pirates of the Caribbean." 

"Python is an excellent general-purpose dynamic language because it's easy to understand and implement. It's popular for creating various apps for mobile phones because of its interactive environment. It runs on the major operating systems, and there are many frameworks for using Python. For instance, Pyramid, Circuits, and CherryPy as well as other frameworks are Flask, Web2Py, Pycnic and Django."

"MySQL, SQLite, and PostgreSQL are the most common databases supported by Python. Since SQLite can only handle a single connection, it's built into Python and retrieved through sqlite3. Python also supports MongoDB, Oracle, Microsoft SQL Server, and Microsoft Access."

"Sets of data include a tuple, list, set, and dictionary. Parentheses represent a tuple, brackets show a list, and braces indicate set and dictionary. Tuples are Python objects separated by commas, equal to lists, and absolute. Accessible in a read-only format, tuples are static and accessed only by interpreters. Tuples store data in a single row, multiple rows, and columns. Lists also store data in a single row, multiple rows and columns, but represent the most powerful tool of Python. Set collections are data that allow mathematical operations. Finally, dictionary collections are unordered data.” 

"PEP8 provides guidelines about Python best practises. The acronym stands for Python Enhancement Proposal. Its purpose is to format Python code to make it readable." 

“Python manages memory with private heap space. The private heap holds Python objects and data structures. The memory manager assigns objects. The garbage collector recycles any unused memory and routes it to the heap space.”

“The inheritance function gives one class the characteristics and methods of another class. The child class, or the derived class, gains the characteristics. Super-class is the data sending the characteristics. The reason for inheritance is to create and maintain apps and deliver code reusability. Python supports three types of inheritance. One is the single inheritance where a derived class obtains a single superclass. The second Python inheritance is multi faceted where data can inherit a derived class from another. Finally, the multiple inheritance means that a child class receives all the methods and attributes from one or more base, or parent, classes.”

“I have used Memcaching in a previous position, however, it can be controversial. It's a distributed memory caching system. It reduces the times an external data source must be read, and it's used to speed up some websites. You must import a library to use the function. It's a free open-source software and runs on Unix and Microsoft Windows. I don't use Memcached in Python projects for several reasons. It's not a data store, which is a typical misuse and requires a second source for storing data. You can't query data, extract information, and it doesn't have any encryption or authentication security.”   

"An array is a special variable that holds more than one value at a time. Python doesn't have built-in arrays, so instead, we can use lists. Alternatively, to develop arrays in Python I might import a library like NumPy. Arrays contain mixed data types, and the numarray module even provides support for IDL-style array operations, multi-dimensional array, and the 'where' function. The numarray only works with numbers, and its length is the highest array index plus one. Lists support objects and strings but can also convert to arrays."

"There are three important errors I look for. They are the ArithmeticError, ImportError, and the IndexError. The Arithmetic Error is when arithmetic operations need revisions. The ImportError occurs when a typo in a module missing from the standard path, or in the module name. The IndexError happens when you reference an out-of-range sequence. These errors come up when the interpreter comes across them. Handling errors add to the strength of the code, guarding against failures causing the programme to close."
