Reading/writing text and APIs for Data Analysis with Python - Part 6
Learn to read and write data in Python using Pandas, covering text, binary, and API formats like CSV, JSON, and HTML.
Watch on YouTube ↗Key takeaways
- 📚Pandas provides versatile `read_csv` options to handle different delimiters (comma, whitespace), missing headers, and custom column names.01:41
- 🚀Experiment with `read_csv` parameters like `sep`, `header`, and `skiprows` to handle diverse text file formats.01:41
- 🧹When reading files, `read_csv` allows skipping specific rows (e.g., comments) and automatically handles missing values by representing them as `NaN`.04:30
- 🧩For large files, use `read_csv` with `chunksize` to process data in manageable pieces, enabling iterative analysis and memory efficiency.07:53
- 💻Utilize `chunksize` in `read_csv` or `read_json` for processing large datasets that may not fit into memory.07:53
- 📝Pandas `to_csv` can write DataFrames to files, allowing customization of delimiters, and explicit representation of missing values (e.g., as 'null').09:37
