Revealing the shortcut keys for PyCharm code formatting

PyCharm is a Python integrated development environment (IDE) that is very popular among developers. It provides many powerful features to help developers improve their work efficiency. One of the most important features is code formatting. Through code formatting, we can make the code more standardized and readable in structure and format. This article will introduce the code formatting function and corresponding shortcut keys in PyCharm, hoping to provide you with some help.

In PyCharm, code formatting is mainly achieved through shortcut keys. If you are using Windows operating system, you can format selected code blocks or the entire file by pressing "Ctrl Alt L". If you are using Mac operating system, you need to press "Command Option L".

Below, we will demonstrate the effect of code formatting through some specific Python code examples.

First, let’s look at an unformatted code example:

def calculate_average(numbers):
    total = 0
    count = 0
    for num in numbers:
    if num % 2 == 0:
    total += num
    count += 1
    average = total / count
    return average


numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
print("Average:", calculate_average(numbers))

The indentation of this code is not standardized, resulting in poor readability of the code. In order to make the code more readable, we can use PyCharm's code formatting function to make adjustments:

def calculate_average(numbers):
    total = 0
    count = 0
    for num in numbers:
        if num % 2 == 0:
            total += num
            count += 1
    average = total / count
    return average


numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
print("Average:", calculate_average(numbers))

After formatting, the indentation of the code is standardized, making it easier to identify the relationship between code blocks. This is useful when working with longer code files.

In addition, PyCharm's code formatting function can also automatically adjust blank lines, spaces, newlines, etc. of the code.

Here is an example:

def calculate_average(numbers):
    total = 0

    count = 0
    for num in numbers:
        if num % 2 == 0:
            total += num
            count += 1

    average = total / count

    return average


numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

print("Average:", calculate_average(numbers))

In this example, we have made the code more readable by adding some blank lines, and we have added spaces around the operators to make the code clearer .

In addition to using shortcut keys for code formatting, PyCharm also provides other code formatting options that can be adjusted according to personal preferences. For example, you can find the "Code Style" option in "Preferences" (Mac) or "Settings" (Windows) to adjust settings such as indentation, spaces, line breaks, etc. of the code.

To sum up, PyCharm’s code formatting function is a powerful tool that developers cannot ignore. By using code formatting, we can make the code more standardized and readable in structure and format. I hope this article can help you better use PyCharm's code formatting function in daily development.
