PyCharm Practice: How to correctly use code automatic line wrapping

In daily programming work, we often encounter situations where some lines of code are too long, which not only makes reading It brings difficulties and makes understanding the code logic more complicated. In order to solve this problem, PyCharm provides automatic code wrapping function to help developers easily optimize the code structure and improve coding efficiency and readability.

This article will introduce how to correctly use the code automatic line wrapping function in PyCharm, and demonstrate its use through specific code examples.

1. Enable automatic line wrapping function

First, open the code file that requires automatic line wrapping in PyCharm. Click the "Code" menu in the editor, and then select the "Hard wrap" option under the "Wrap/Unwrap" menu, or use the shortcut key Ctrl Alt Shift Enter to turn on the automatic word wrapping function.

2. Settings for automatic line wrapping

In PyCharm, you can set the options for automatic line wrapping of code according to personal preferences and project specifications. Click the "File" menu, select "Settings", and then find the "Hard wrap at" option in "Editor" -> "Code Style". You can set the number of characters the code will automatically wrap at. It is recommended to set it to 80 or 100 characters.

3. Code Example

The following uses a specific Python code example to demonstrate how to correctly use the code automatic line wrapping function in PyCharm:

def calculate_sum(a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z):
    total_sum = a + b + c + d + e + f + g + h + i + j + k + l + m + n + o + p + q + r + s + t + u + v + w + x + y + z
    return total_sum

result = calculate_sum(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
print(result)

In the above code , function calculate_sum receives 26 parameters. Without automatic line wrapping, a line of code is very long and difficult to read. We can use PyCharm's automatic word wrapping function to optimize this code into a more readable form.

According to the above settings, automatic line wrapping will be performed when the code length reaches 80 characters. The modified code is as follows:

def calculate_sum(a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z):
    total_sum = (a + b + c + d + e + f + g + h + i + j + k + l + m + n + o +
                 p + q + r + s + t + u + v + w + x + y + z)
    return total_sum

result = calculate_sum(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
print(result)

With automatic line wrapping, the code is cleaner and easier to read and maintain.

To summarize, the correct use of PyCharm's code automatic line wrapping function can help us optimize the code structure and improve the readability and maintainability of the code. Properly setting the automatic line wrapping parameters and flexibly using the automatic line wrapping function when needed will make our programming work more efficient and comfortable.
