PyCharm tips in Python

Python is one of the most popular programming languages ​​currently, and PyCharm is the most popular IDE (integrated development environment) for Python development. PyCharm is very powerful, but you may encounter some problems during use. In this article, we’ll share some PyCharm tips to help you write, debug, and optimize Python code faster.

1. Code auto-completion

PyCharm’s code editor has an excellent code auto-completion function. Just start typing the first character of the function or object name and PyCharm will give you a complete list of suggestions, intelligently sorted and filtered based on context and status. We can also use the Tab key to complete code, reducing the amount of keyboard input.

2. Shortcut keys

There are many shortcut keys in PyCharm, some of the commonly used ones include:

Ctrl Shift N: Quickly find resource files.
Ctrl Shift Alt N: Quickly find configuration settings.
Ctrl Alt L: Reformat the code.
Ctrl A: Select all.
Alt Enter: Prompt solution.
Ctrl Z: Undo the previous operation.
Ctrl D: Copy the current line or current selection.
Ctrl F: Find text.
Ctrl G: Go to line.

Use these shortcut keys to improve the efficiency of code writing.

3. Refactoring

Code refactoring is a very useful task, it can help us refactor, organize and optimize the code. Code refactoring in PyCharm is easy, and you can update multiple pieces of code at once. Some commonly used refactoring tools include:

Rename: Rename variables, functions, classes, etc.
Extract Method: Extract code into a separate function or method.
Extract Variable: Extract the expression into a variable.
Inline Variable: Replace a variable with its value.
Move Class: Move the class to another file or directory.

4. Breakpoint debugging

Debugging is an important task. Marking breakpoints is a very useful debugging technique. Let us stop when the code execution reaches a certain point and check Variable values, program state, and logic flow. PyCharm integrates a powerful debugger that can help us debug code. There are some commonly used debugging operations, including:

F7: Statement-by-statement debugging.
F8: Skip statement.
F9: Continue execution.
Shift F9: Restart the debugger.
Shift Ctrl F8: Conditional breakpoint.

5. Version Control

Version control is an important development tool that can help us track code changes, manage different versions of the code, and perform tasks such as code rollback and merging. PyCharm supports a variety of version control tools, including Git, SVN and Mercurial. When using PyCharm, you can use version control tools such as Git and GitHub for code version control.

Summary

In this article, we have shared some PyCharm tips, hoping that these tips can help you better use PyCharm to write, debug and optimize Python code. PyCharm has rich functions and powerful extensibility, making Python development more efficient and enjoyable.
