Guide to using PyCharm shortcut keys to improve running efficiency

"PyCharm Running Shortcut Key Usage Guide"

PyCharm is an integrated development environment (IDE) developed by JetBrains for Python programming. It provides a rich set of features and tools to help developers code, debug, and test more efficiently. In PyCharm, the use of shortcut keys is one of the keys to improving work efficiency. This article will introduce in detail the commonly used running shortcut keys of PyCharm, and attach specific code examples to help readers better master the usage skills of PyCharm.

1. Run program shortcut keys: In PyCharm, we often need to run the programs we write. Using shortcut keys can help us execute code quickly without having to frequently use the mouse to click the "Run" button on the menu bar. In PyCharm, the default running shortcut key is "Shift F10". By pressing this set of shortcut keys, you can directly execute the code in the current editor. The following is a simple Python code example:

print("Hello, PyCharm!")

After pressing "Shift F10", the program will output "Hello, PyCharm!" in the PyCharm run panel.

2. Debugger shortcut keys: During the debugging process, we often need to run the code and view the variable values ​​​​line by line during the code execution. PyCharm provides rich debugging functions, and using shortcut keys can help us debug more efficiently. In PyCharm, the default debugging shortcut key is "Shift F9". By pressing this set of shortcut keys, you can start debugging the code in the current editor. The following is a simple Python code example:

x = 5
y = 10
result = x + y
print(result)

After pressing "Shift F9", the program will be executed in the code debugging mode and the variables x, The values ​​of y and result.

3. Shortcut keys for running unit tests: Unit testing is a very important part of the software development process and can help us ensure the quality and correctness of the code. PyCharm has built-in support for unit testing. You can easily run unit tests and view test results using shortcut keys. In PyCharm, the default shortcut key for running unit tests is "Ctrl Shift R". By pressing this set of shortcut keys, you can run the unit test at the current cursor position. The following is a simple Python unit test example:

import unittest

def add(x, y):
    return x + y

class TestAddFunction(unittest.TestCase):
    def test_add(self):
        self.assertEqual(add(3, 5), 8)
    
if __name__ == '__main__':
    unittest.main()

After pressing "Ctrl Shift R" at the beginning of the line of the test method test_add, PyCharm will execute this unit test method , and display the test results in the run panel.

By mastering the above-mentioned PyCharm running shortcut keys, developers can develop, debug and test code more quickly and improve work efficiency. At the same time, by constantly practicing and using these shortcut keys, we can become more proficient in operating PyCharm, making programming work easier and more enjoyable. I hope this article can be helpful to readers in their development work in PyCharm.
