The .pyc extension stands for “Python compiled file”. When you run a Python script, the interpreter compiles the code into bytecode, which is a low-level representation of the code that can be executed more efficiently. The bytecode is stored in a .pyc file, which is created in the same directory as the .py file when it is first run.
The .pyc file contains the compiled bytecode for the corresponding .py file, which allows the Python interpreter to execute the code more quickly on subsequent runs of the script. When you run the script again, the interpreter first checks if the .pyc file is up-to-date with the .py file. If it is, the interpreter will use the .pyc file instead of recompiling the code, which can save time.
