The Python programming language has gained ground in the world in recent years. Programmers use this versatile language in various software, data science, automation, and web development, among others.

What Is Python?

This computer programming language builds software and websites, conducts data analysis, and automates various tasks. Guido van Rossum conceived and implemented it in the late 1980s at Centrum Wiskunde & Informatica (CWI). This general-purpose language creates various programs specialized for different problems. Due to its beginner-friendliness and versatility, Python ranks as one of the most used programming languages in recent years, according to a survey report by RedMonk, an industry analyst firm in Portland, Maine, United States.

How Does Python Work?

The Python language has quite common terms, like bytecode vs. machine code, compiled vs. interpreted, garbage vs. collectors, dynamic typing vs. static typing, etc. When you write a C program, it should be compiled. Compilation means translating code understandable by humans to codes only discernible by the machine, called machine code. Then, the machine codes assume the base level form of the program instructions executed by the CPU directly.

In most applications, Python is an interpreted language that requires compilation. For example, this code written as a .py file should first compile to bytecode stored in a .pyo or .pyc format. The bytecode is a low-level file of program instructions that an interpreter can efficiently execute. The interpreter can either be the CPU or an installed Python interpreter. A prefix attaches to the name python to denote an interpreter installed. For example, CPython implies that the python interpreter is implemented in the C language, while JPython is implemented in Java.

Which Jobs Require Python Knowledge?

Programmers use Python for developing software and websites, data analysis, task automation, and data visualization. Other non-programmers, like scientists and accountants, also adopted Python for various daily tasks such as organizing finances.

1. Machine Learning and Data Analysis

Python has gained ground in data science, enabling data analysts and other professionals to compute complex statistical tasks, build machine-controlled algorithms, create data visualization, analyze and manipulate data.

Programmers use Python to build data visualizations such as bar and line graphs, histograms, pie charts, and 3-dimensional plots. It also has libraries like Keras and TensorFlow that enable a coder to write programs for efficient and quick machine learning and data analysis.

2. Web Development 

Programmers use Python to develop the back end of an application or a website. Its primary roles in web development include communicating with databases, sending and receiving data from servers, ensuring security and URL routing.

3. Scripting or Automation

Programmers use Python to perform tasks with repetitive instructions effectively through automation. Scripting refers to the process of writing code used to build automation. Then, the automation converts files, checks errors, removes duplicates, and executes simple mathematics.
