PandasDataFrame.compare()function is used to compare given DataFrames row by row along with the specified align_axis. Sometimes we have two or more DataFrames having the same data with slight changes, in those situations we need to observe thedifference between two DataFrames. By default,compare...
“ValueError: can only compare identically-labeled dataframe objects” is a common error that occurs when comparing two pandas DataFrames with different column names or row labels. This error can be confusing, as it suggests that the dataframes are completely different objects when in fact, they ...

We can compare two DataFrames and see the difference using the DataFrame.compare() method. The below example shows the same.#importing pandas as pd import pandas as pd df1 = pd.DataFrame([['Abhishek',100,'Science',90], ['Anurag',101,'Science',85]], columns=['Name', 'Roll No', '...

To fix this error, we can either reshape the DataFrames to have the same dimensions or select a subset of columns which is present in both DataFrames. Let’s take a look at the example: import pandas as pd # Create two DataFrames with different dimensions ...
