Pandas is a Python library for data analysis. Pandas' primary data structures are DataFrames, which make it easier to perform analytical tasks in Python.
Python Copy In this example, we merged two DataFrames with different indexes, resulting in a DataFrame with a multi-index. By usingreset_index(), we simplified the DataFrame to a single-level index. Further Resources for Pandas Library
