If you don’t want Black to change your file, but you want to know if Black thinks a file should be changed, you can use one of the following commands:īlack -check. Three python files within the folder named python_with_black have been reformatted. Format all python files inside the folder To format more than one python file, write black folder_name/ in the terminal.

The Python code is now formatted and it’s more readable. Then you can open sample_code.py to see formatted python code: After running Black, you will see the following output: You can use black sample_code.py in the terminal to change the format. Let's look at this simple example: here are my two python functions in my python file called sample_code.py. To get started right away with sensible defaults, choose the python file you want to format and then write black filename.py in the terminal. Once Black is installed, you will have a new command-line tool called black available to you in your shell, and you’re ready to start!

Install Blackīlack can be installed by running pip install black. It helps your brain focus on the problem you want to solve and code solutions, rather than getting distracted by code structure and minor stylistic differences. You will save time and mental energy for more important matters.īlack can reformat your entire file in place according to the Black code style. In return, Black gives you speed, determinism, and freedom from pycodestyle nagging about formatting. Introduction to Black Black Logoįrom the project README: By using Black, you agree to cede control over minutiae of hand-formatting. The problem is that these tools only report the problems they identify in the source code and leave the burden to the Python developers to fix them!īut what if we had a tool that could identify and solve the problem at the same time? Black is a tool that allows you to identify errors and format your python code at the same time. It is a great toolkit for checking your code base against coding style (PEP8), programming errors like “library imported but unused”, “Undefined name” and code which is not indented. It can also look for certain type errors, it can recommend suggestions about how particular blocks can be refactored, and can offer you details about the code’s complexity.įlake8 is a Python library that wraps PyFlakes, pycodestyle and Ned Batchelder’s McCabe script.

It tries to enforce a coding standard and looks for code smells. Pylint is a tool that checks for errors in Python. Most Python developers enjoy using Pylint or Flake8 to check their code for errors and style guides. It is also just really horrible to look at. It makes it easy to spot bugsīadly formatted code can make it really, really hard to spot bugs or even to work on a program. Otherwise it becomes harder to work together.

Several people will likely be working on the same software project and code you write must be understood by your teammates. Team supportįormatting your code becomes more important when you are working in a team. If you forget to do that formatting you might lose your job prospects, just because of your poorly formatted code. When you're in a coding interview, sometime the interviewers will care if you’re formatting your code properly. It looks more organized, and when someone looks at your code they'll get a good impression. Why formatting your python code is important Readabilityįormatting your code will help you read your code efficiently.

The difference between working on well-formatted code and working on badly formatted code is like the difference between living in a palace and living in a dirty house. At some point (around 15,000 lines of code), it becomes harder to understand the code that you yourself wrote. If you write a small program (with 1000 lines of codes) you can probably get away without formatting your code.īut as programs get more and more complex, they get harder and harder to understand. Junior programmers often focus on making sure their code is working and forget to format the code properly along the way. Writing Python code is one thing and writing the code in a good format is another thing.
