Quickly master the shortcut keys for running PyCharm

PyCharm is a powerful Python integrated development environment that can improve development efficiency through flexible shortcut keys. This article will introduce you to the commonly used running shortcut keys in PyCharm, and provide specific code examples to help you quickly get started using PyCharm.

First of all, we need to understand the most basic running shortcut key in PyCharm: running the program. In PyCharm, you can use the shortcut key "Shift F10" to run the current Python program. Here is a simple sample code:

print("Hello, World!")

You can save the above code to a Python file, and then use the "Shift F10" shortcut key to run the program. In PyCharm's console, you will see the output "Hello, World!".

In addition to running the program directly, you can also use shortcut keys for debugging. In PyCharm, use "Shift F9" to start debug mode. Next, let's look at a sample code with breakpoints:

def add(a, b):
    return a + b

result = add(3, 5)
print(result)

In the above code, we define a simple addition function and call it. You can set a breakpoint by right-clicking on the left side of the return a b line and selecting "Toggle Line Breakpoint". Then use "Shift F9" to start debug mode. The program will stop at the breakpoint and you can debug the code line by line.

Also, if you want to run a specific block of code in the current file, you can use "Ctrl Shift F10" to run the selected code. Here is a sample code that demonstrates how to use the selective run feature:

def multiply(x, y):
    return x * y

result = multiply(4, 6)
print(result)

# 选中以下三行代码
a = 10
b = 5
print(a + b)

In the above code, we define a multiplication function and some additional calculations. Select the three lines of code a = 10, b = 5 and print(a b), and then use the "Ctrl Shift F10" shortcut key to run only the selected code block.

Finally, you can also use the shortcut key "Ctrl Shift F9" to re-run the last executed program. This feature is very useful when the same piece of code needs to be executed repeatedly.

By mastering these running shortcut keys in PyCharm, you can improve the efficiency of code debugging and running, and save valuable time. I hope the content of this article can help you better use PyCharm to develop Python programs.
