In the following code, we have created two data frames and combined them using theconcat()function. We have passed the two data frames as a list to theconcat()function. Example Code: importpandasaspd df1=pd.DataFrame({"id":["ID1","ID2","ID3","!D4"],"Names":["Harry","Petter",...

The Pandas library was written specifically for the Python programming languages, and it lets you merge data sets, read records, group data and organise information in a way that best supports the analysis required.
# Pandas: Keep the Index when merging DataFrames using join() You can also use the DataFrame.join() method to keep the index when merging DataFrames. main.py import pandas as pd df1 = pd.DataFrame({ 'year': [2020, 2021, 2022, 2023], 'profit': [1500, 2500, 3500, 4500], }, in...
