PyCharm tutorial: quickly master the automatic line wrapping function

PyCharm is a powerful Python integrated development environment. Its automatic line wrapping function can help developers write code more efficiently. This article will introduce how to quickly master the automatic word wrapping function in PyCharm and provide specific code examples.

1. Enable automatic word wrapping function
In PyCharm, the automatic word wrapping function is not enabled by default and needs to be manually set before it can be used. The specific steps are as follows:

1. Open PyCharm and enter File -> Settings;
2. In the Settings window, select Editor -> Code Style -> Python;
3. In the tab on the right, check the checkbox behind "Right margin (columns)" and set the appropriate line width. It is generally recommended to set it to 80 or 100;
4. Click OK Save Settings.

After enabling the automatic line wrapping function, when the length of the code exceeds the set line width, PyCharm will automatically wrap the code and display it, making the code clearer and easier to read.

2. Code Example
Next, we will use a specific code example to demonstrate how the automatic line wrapping function in PyCharm works. Suppose we have a Python function that calculates the first n terms of the Fibonacci sequence. The code is as follows:

def fibonacci(n):
    if n <= 1:
        return n
    else:
        return fibonacci(n-1) + fibonacci(n-2)

In PyCharm, if we set the line width to 80 and paste the above code Go to PyCharm for editing. When the code exceeds 80 characters, PyCharm will automatically wrap the code and display it, for example:

def fibonacci(n):
    if n <= 1:
        return n
    else:
        return fibonacci(n-1) + fibonacci(n-2)

Through the automatic line wrap function, we can see that the code is automatically wrapped and displayed, making the code as a whole More beautiful and easier to read.

3. Summary
This article introduces how to quickly master the automatic line wrapping function in PyCharm, and provides specific code examples for demonstration. By enabling the automatic line wrapping function, the code can be automatically wrapped and displayed when it exceeds the set line width, improving the readability and maintainability of the code. I hope this article will help you use the automatic word wrap function in PyCharm. Happy programming!
