You can pass two DataFrames to be merged into the pandas.merge() method. This function collects all common columns in both DataFrames and replaces each common column in both DataFrames with a single one. It merges the DataFrames df and df1 assigned tomerged_df. By default, themerge()met...
In this exercise, we have merged two DataFrames on a single common column using pd.merge(). Sample Solution: Code : importpandasaspd# Create two sample DataFramesdf1=pd.DataFrame({'ID':[1,2,3],'Name':['Selena','Annabel','Caeso']})df2=pd.DataFrame({'ID':[2,3,4],'Age':[25,...
15. Merge with Custom Sorting Write a Pandas program to merge DataFrames with custom sorting. This exercise demonstrates how to merge two DataFrames and sort the result by a specific column. Sample Solution: Code : importpandasaspd# Create two sample DataFramesdf1=pd.DataFrame({'ID':[1,2,3...
