How can I optimize my Pandas DataFrame operations?
You can optimize your Pandas operations by using vectorized functions, avoiding loops, and utilizing the apply method wisely.
What are some common performance bottlenecks in Pandas?
Common bottlenecks include using loops instead of vectorized operations, excessive copying of DataFrames, and inefficient data types.
Can you give me an example of using apply effectively?
Sure! Instead of looping through rows, you can use df['column'].apply(lambda x: x + 1) to increment each value in a column.
How can I reduce memory usage in my DataFrame?
You can reduce memory usage by downcasting numeric types, using categorical data types for strings, and dropping unnecessary columns.
