PyCharm multi-line comment shortcut keys: Make code comments more convenient, specific code examples are needed

In daily programming work, code comments are a very important part. It not only improves the readability and maintainability of the code, but also helps other developers understand the intent and design ideas of the code. However, manually adding code comments is often a time-consuming and tedious task. In order to make our code comments more efficient, PyCharm provides shortcut keys for multi-line comments.

In PyCharm, we can use Ctrl / to add single-line comments. This shortcut key can comment out the selected line or lines of code, or uncomment the selected lines. However, for situations where you need to add multi-line comments, Ctrl / is no longer suitable. In this case, we need to use another shortcut key to add multi-line comments.

The multi-line comment shortcut key in PyCharm is Ctrl Shift /. This shortcut key can automatically add comments to a selected continuous section of code, or uncomment the selected section.

The following is a specific code example to demonstrate how to use PyCharm's multi-line comment shortcut keys:

def is_even(num):
    """
    判断一个数是否为偶数
    :param num: 需要判断的数
    :return: 如果是偶数返回True，否则返回False
    """
    if num % 2 == 0:
        return True
    else:
        return False


def calculate_average(nums):
    """
    计算一个列表中所有数的平均值
    :param nums: 包含数字的列表
    :return: 平均值
    """
    total = sum(nums)
    average = total / len(nums)
    return average


# 使用多行注释快捷键添加对is_even函数的注释
# Ctrl+Shift+/
def is_odd(num):
    """
    判断一个数是否是奇数
    :param num: 需要判断的数
    :return: 如果是奇数返回True，否则返回False
    """
    return not is_even(num)


nums = [1, 2, 3, 4, 5]
# 使用多行注释快捷键添加对calculate_average函数的注释
# Ctrl+Shift+/
average = calculate_average(nums)

print("Is 3 odd?", is_odd(3))
print("Average:", average)

In the above code example, we define two functions is_even and calculate_average, and A sample code using these two functions. We can use PyCharm's multi-line comment shortcut Ctrl Shift / to add comments to these two functions. In this way, we can quickly understand the functions and parameters of these two functions.

To summarize, PyCharm’s multi-line comment shortcut key Ctrl Shift / can help us quickly add and cancel multi-line comments, making code comments more convenient. When we need to add comments to a continuous piece of code, this shortcut key can help us save the trouble of manually adding comments for each line. In daily programming work, rational use of multi-line comment shortcut keys can improve our work efficiency and enhance the readability and maintainability of the code.
