When processing large data sets that exceed memory in Python, they cannot be loaded into RAM at one time. Instead, strategies such as chunking processing, disk storage or streaming should be adopted; CSV files can be read in chunks through Pandas' chunksize parameters and processed block by block. Dask can be used to realize parallelization and task scheduling similar to Pandas syntax to support large memory data operations. Write generator functions to read text files line by line to reduce memory usage. Use Parquet columnar storage format combined with PyArrow to efficiently read specific columns or row groups. Use NumPy's memmap to memory map large numerical arrays to access data fragments on demand, or store data in lightweight data such as SQLite or DuckDB.

Make sure that Python is installed and added to the system PATH, run python--version or python3--version verification through the terminal; 2. Save the Python file as a .py extension, such as hello.py; 3. Create a custom build system in SublimeText, Windows users use {"cmd":["python","-u","$file"]}, macOS/Linux users use {"cmd":["python3

To debug Python scripts, you need to first install the Python extension and configure the interpreter, then create a launch.json file to set the debugging configuration, then set a breakpoint in the code and press F5 to start the debugging. The script will be paused at the breakpoint, allowing checking variables and step-by-step execution. Finally, by checking the problem by viewing the console output, adding logs or adjusting parameters, etc., to ensure that the debugging process is simple and efficient after the environment is correct.

The yield keyword is used to define a generator function, so that it can pause execution and return values one by one, and then recover from the pause; the generator function returns a generator object, has lazy evaluation characteristics, and can save memory. It is suitable for handling scenarios such as large files, streaming data, and infinite sequences. The generator is an iterator that supports next() and for loops, but cannot be rewind and must be recreated to iterate again.
