4 min readTo make a difference between two Pandas dataframes, you can perform various operations to identify the differences in the data. Here are some approaches you can consider:Comparing values: You can directly compare the two dataframes to identify the differences in values using boolean operations. For example, you can use the == operator to check if two dataframes are equal, resulting in a dataframe with True or False values for each element.
