What are some effective data manipulation techniques in Python?

Some effective techniques include using libraries like Pandas for data frames, NumPy for numerical data, and list comprehensions for efficient data processing.

Can you give me an example of using Pandas for data manipulation?

Sure! You can use Pandas to read a CSV file and perform operations like filtering, grouping, and aggregating data. For example:

import pandas as pd

df = pd.read_csv('data.csv')
filtered_df = df[df['column_name'] > value]

What about handling missing data in Pandas?

You can handle missing data in Pandas using methods like fillna() to fill missing values or dropna() to remove rows with missing values.

Are there any performance tips for manipulating large datasets?

Yes! Use vectorized operations instead of loops, consider using Dask for out-of-core computation, and optimize data types to save memory.
