Python Pandas Frequently Asked Questions (FAQ):

  1. What is Python Pandas?

    • Pandas is a powerful, open-source data analysis and manipulation library for Python. It provides data structures and functions needed to manipulate structured data.

  2. What are the main data structures in Pandas?

    • Pandas primarily uses two data structures – Series (1-dimensional) and DataFrame (2-dimensional). These data structures handle a vast majority of use cases in finance, statistics, social science, and many areas of engineering.

  3. Why is Pandas preferred for data analysis in Python?

    • Pandas is preferred because it allows fast analysis and data cleaning and preparation. It also excels in performance and productivity, and has built-in data visualization features.

  4. Is Pandas built on top of NumPy?

    • Yes, Pandas is built on top of NumPy, which means that a lot of the structure of NumPy is used or replicated in Pandas. Data in pandas is often used to feed statistical analysis in SciPy, plotting functions from Matplotlib, and machine learning algorithms in Scikit-learn.

  5. How do I install Pandas?

    • You can install Pandas using pip or conda command. For pip, use “pip install pandas”, and for conda, use “conda install pandas”. Make sure that you have Python installed before this step.

  6. What does the ‘groupby’ function do in Pandas?

    • ‘groupby’ function is used to split the data into groups based on some criteria. Pandas objects can be split on any of their axes. The abstract definition of grouping is to provide a mapping of labels to group names.

  7. What is the difference between ‘join’ and ‘merge’ in Pandas?

    • Both ‘join’ and ‘merge’ can be used to combine two dataframes but the join method combines dataframes on the basis of their indexes whereas the merge method is more versatile and allows us to specify columns besides the index to join on for both dataframes.

  8. How is handling missing values done in Pandas?

    • Pandas provide several methods to clean or fill missing values like dropna(), fillna(), replace(), and interpolate().
