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.

This example shows an interactive web application built on PythonPlotlyDash. 1. Create a web application interface using Dash. 2. Select data series (Sales, Profit, Expenses) through the drop-down menu (Dropdown). 3. Use Plotly to dynamically draw the corresponding time series line chart. 4. The data is a simulated 100-day time series and converted into a long format for easy drawing. 5. The callback function updates the chart content in real time according to the user's choice. After running, the application is started on the local server and can be accessed through the browser. It supports dynamic interaction and real-time updates. It is suitable for beginners to understand the basic structure and response mechanism of Dash. It can also be added and accessed by real data.
