Master the common shortcut keys of PyCharm and optimize the coding speed!

Familiarize yourself with PyCharm’s commonly used shortcut keys to improve coding efficiency!

In the process of software development, improving coding efficiency is the goal pursued by every developer. For Python developers, being familiar with and flexibly using PyCharm's common shortcut keys is an important way to improve coding efficiency. This article will introduce some commonly used PyCharm shortcut keys to help readers better use this powerful Python development tool.

1. Format code
   In PyCharm, press Ctrl Alt L to format the code. This shortcut key can automatically adjust the indentation, blank lines, spaces, etc. of the code according to the PEP 8 specification, making the code cleaner and easier to read.
2. Comment code
   Ctrl/ shortcut key can quickly comment selected lines of code, while Shift Ctrl/ can comment out entire code blocks. This is very useful when debugging and code sharing.
3. Find and Replace
   Press Ctrl F to find a specific string in the current file. And press Ctrl R to replace in the current file. If you need to find or replace across the entire project, you can use Ctrl Shift F and Ctrl Shift R.
4. Copy, Cut and Paste
   Ctrl C and Ctrl X are used to copy and cut the selected code respectively. And Ctrl V is for pasting. It is worth mentioning that in PyCharm, you can also use the Ctrl D shortcut key to copy the current line, or use the Ctrl Y shortcut key to delete the current line.
5. Code completion
   PyCharm has a powerful code completion function. Press Ctrl+Space to get completion suggestions as you type code. At the same time, PyCharm can also provide corresponding automatic completion based on the entered variable and function names.
6. Jump to definition
   During the development process, we often need to view the definition of a certain variable or function. In PyCharm, pressing Ctrl and the left mouse button can quickly jump to the defined place, improving our viewing efficiency.
7. Code Indentation
   When writing code, correct indentation is very important. PyCharm provides shortcut keys for quickly adjusting indentation. Press the Tab key to indent the selected line of code to the right, and press the Shift Tab key to indent the selected line of code to the left.
8. Code folding
   If our code file is very long and contains many unnecessary code segments, we can use PyCharm's code folding function. Press Ctrl "-" to collapse the selected code segment, and press Ctrl " " to expand the collapsed code segment.
9. Auto-complete brackets and quotation marks
   When writing code, we often encounter situations where we forget to enter brackets or quotation marks. PyCharm provides the function of automatically completing brackets and quotes. Just enter the opening bracket, quotation mark or double quotation mark, PyCharm will automatically insert the corresponding closing bracket, quotation mark or double quotation mark and position the cursor in the middle.
10. Running and debugging code
    In PyCharm, running and debugging code is very convenient. Press Ctrl Shift F10 to run the current file or selected code. Press F9 to set a breakpoint in the current file, and press F8 to execute the code line by line.

By becoming familiar with and flexibly using PyCharm's shortcut keys, we can write, debug and modify code faster. The use of these shortcut keys takes some time and practice to master, but once we master them, we will be able to increase our coding efficiency with half the effort.

In short, being familiar with PyCharm’s common shortcut keys is one of the essential skills for every Python developer. By rationally using these shortcut keys, we can develop code more efficiently, improve work efficiency, and reduce duplication of work. Therefore, it is strongly recommended that you try to use these shortcut keys in your daily work to improve coding efficiency and complete tasks quickly.
