What are the best practices for using dataframe libraries?
When using dataframe libraries, it's important to follow best practices like optimizing memory usage, using vectorized operations, and ensuring data integrity.
Can you explain what vectorized operations are?
Vectorized operations allow you to perform operations on entire arrays or columns of data at once, which is much faster than looping through individual elements.
How can I optimize memory usage when working with large dataframes?
You can optimize memory usage by using appropriate data types, filtering data early, and using techniques like chunking to process data in smaller pieces.
What are some common pitfalls to avoid?
Common pitfalls include not handling missing data properly, using inefficient data types, and neglecting to profile your code for performance.
