Python, one of the most popular programming languages in the world, has created everything from Netflix鈥檚 recommendation algorithm to the software that controls self-driving cars. Python is a general-purpose language, which means it鈥檚 designed to be used in a range of applications, including data science, software and web development, automation, and generally getting stuff done.

In this article, you'll learn more about what Python is and how it's used in the real world. If you want to start learning this popular programming language today, consider enrolling in the University of Michigan's Python for Everybody Specialization where you'll build foundational programming knowledge in as little as two months.

What is Python?

Python is a computer programming language often used to build websites and software, automate tasks, and conduct data analysis. Python is a general-purpose language, meaning it can be used to create a variety of different programs and isn鈥檛 specialized for any specific problems. This versatility, along with its beginner-friendliness, has made it one of the most-used programming languages today.

According to a study by Statista, Python is the third most commonly used programming language among developers worldwide [].

Did you know? The name Python comes from Monty Python. When Guido van Rossum was creating Python, he was also reading the scripts from BBC鈥檚 Monty Python鈥檚 Flying Circus. He thought the name Python was appropriately short and slightly mysterious.

What is Python used for?

Python is commonly used for developing websites and software, task automation, data analysis, and data visualization. Since it鈥檚 relatively easy to learn, Python has been adopted by many non-programmers, such as accountants and scientists, for a variety of everyday tasks, like organizing finances.

鈥淲riting programs is a very creative and rewarding activity,鈥� says University of Michigan and 糖心vlog官网观看 instructor Charles R Severance in his book Python for Everybody. 鈥淵ou can write programs for many reasons, ranging from making your living to solving a difficult data analysis problem to having fun to helping someone else solve a problem.鈥�

What can you do with Python? Some things include:

• Data analysis and machine learning

• Web development

• Automation or scripting

• Software testing and prototyping

• Everyday tasks

Here鈥檚 a closer look at some of these common ways Python is used.

1. Data analysis and machine learning

Python has become a staple in data science, allowing data analysts and other professionals to use the language to conduct complex statistical calculations, create data visualizations, build machine learning algorithms, manipulate and analyze data, and complete other data-related tasks.

Python can build a wide range of different data visualizations, like line and bar graphs, pie charts, histograms, and 3D plots. Python also has a number of libraries that enable coders to write programs for data analysis and machine learning more quickly and efficiently, like TensorFlow and Keras.

2. Web development

Python is often used to develop the back end of a website or application鈥攖he parts that a user doesn鈥檛 see. Python鈥檚 role in web development can include sending data to and from servers, processing data and communicating with databases, URL routing, and ensuring security. Python offers several frameworks for web development. Commonly used ones include Django and Flask.

Some web development jobs that use Python include back-end engineers, full-stack engineers, Python developers, software engineers, and DevOps engineers.

3. Software testing and prototyping

In software development, Python can aid in tasks like build control, bug tracking, and testing. With Python, software developers can automate testing for new products or features. Some Python tools used for software testing include Green and Requestium.

4. Automation or scripting

If you find yourself performing a task repeatedly, you could work more efficiently by automating it with Python. Writing code used to build these automated processes is called scripting. In the coding world, automation can be used to check for errors across multiple files, convert files, execute simple math, and remove duplicates in data.

Python can even be used by relative beginners to automate simple computer tasks鈥攕uch as renaming files, finding and downloading online content, or sending emails or texts at desired intervals.

IT automation can be a valuable skill to add to your resume. You can learn the basics from an industry leader in technology with the following online program:

5. Everyday tasks

Python isn't only for programmers and data scientists. Learning Python can open new possibilities for those in less data-heavy professions, like journalists, small business owners, or social media marketers. Python can also enable non-programmers to simplify certain tasks in their lives. Here are just a few of the tasks you could automate with Python:

• Keep track of stock market or crypto prices

• Send yourself a text reminder to carry an umbrella anytime it鈥檚 raining

• Update your grocery shopping list

• Renaming large batches of files

• Converting text files to spreadsheets

• Randomly assign chores to family members

• Fill out online forms automatically

Why is Python so popular?

Python is popular for a number of reasons. Here鈥檚 a deeper look at what makes it so versatile and easy to use for coders.

• Its simple syntax mimics natural language, making it easier to read and understand. This makes it quicker to build projects and improve on them.

• 滨迟鈥檚 versatile. Python can be used for many different tasks, from web development to machine learning.

• 滨迟鈥檚 beginner-friendly, making it popular for entry-level coders.

• 滨迟鈥檚 open source, which means it鈥檚 free to use and distribute, even for commercial purposes.

• Python鈥檚 archive of modules and libraries鈥攂undles of code that third-party users have created to expand Python鈥檚 capabilities鈥攊s vast and growing.

• Python has a large and active community that contributes to Python鈥檚 pool of modules and libraries, and acts as a helpful resource for other programmers. The vast support community means that if coders run into a stumbling block, finding a solution is relatively easy; somebody is bound to have encountered the same problem before.
