Sharing practical tips for running PyCharm shortcut keys

PyCharm is a powerful Python integrated development environment (IDE) that provides a wealth of shortcut keys and functions to allow developers to write and debug code more efficiently. This article will share some practical tips for running shortcut keys in PyCharm, with specific code examples to help readers better master these techniques.

1. Run the current file

In PyCharm, you can use the shortcut key Shift F10 to run the currently open Python file. This shortcut key can quickly execute the code currently being edited, which is convenient for debugging and testing.

Sample code:

print("Hello, PyCharm!")

After pressing Shift F10, you will see the output as: Hello, PyCharm!

2. Run the selected code fragment

Sometimes we only need to run a certain part of the code, you can use PyCharm to run the selected code fragment Function. Select the code you want to run, and then press the shortcut key Ctrl Shift E (or select "Evaluate Expression" from the right-click menu) to run the selected code fragment.

Sample code:

a = 10
b = 20
print(a + b)

Select print(a b) and press Ctrl Shift E, the result will be output 30.

3. Running skills in debugging mode

Code debugging in PyCharm is a very common operation. You can use some shortcut keys to help debug the code more efficiently. .

• F8: Execute the code line by line
• F7: Enter inside the function
• Shift F8: Jump out of the current function
• Ctrl F2: Force to stop debugging

Sample code:

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

result = add(5, 10)
print(result)

In In debugging mode, press F8 to execute the code line by line, and press F7 to enter the add function for debugging.

4. Run unit tests

PyCharm provides a convenient unit testing tool that can run defined unit test cases to verify whether the code meets expectations. You can use the shortcut key Ctrl Shift F10 (or right-click on the test class name or method name and select "Run") to run the current unit test.

Sample code:

import unittest

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

class TestAdd(unittest.TestCase):

    def test_add(self):
        self.assertEqual(add(3, 5), 8)

if __name__ == '__main__':
    unittest.main()

Select the TestAdd class or the test_add method and press Ctrl Shift F10, will run the unit test and output the test results.
