How does pandas relate to Python?

pandas is a software library written for the Python programming language for data manipulation and analysis. In particular, it offers data structures and operations for manipulating numerical tables and time series. Its name is a play on the phrase “Python data analysis” itself.

Is NumPy more efficient than pandas?

Numpy is memory efficient. Pandas has a better performance when number of rows is 500K or more. Numpy has a better performance when number of rows is 50K or less. Indexing of the pandas series is very slow as compared to numpy arrays.
