data_merge2 = pd.merge(data1, # Outer join based on index data2, left_index = True, right_index = True, how = "outer") print(data_merge2) # Print merged DataFrameIn Table 4 you can see that we have created a new union of our two pandas DataFrames. This time, we have kept ...
You can also usepandas.concat(), which is particularly helpful when you are joining more than two DataFrames. If you notice in the above example, it just added the row index as-is from two DataFrame, sometimes you may want to reset the index. You can do so by using theignore_index=T...

Because of this, pandas provides several methods of merging and joining datasets to make this necessary job easier: pandas.merge connects rows in DataFrames based on one or more keys. pandas.concat concatenates or “stacks” together objects along an axis. The combine_first instance method lets ...
Data Reading: Reads CSV file data into a pandas DataFrame, setting appropriate column names. Data Validation: Skips plotting if the DataFrame is empty. Velocity Vector Creation: Extracts coordinates, velocity components, and uncertainties (which are not used nor plotted in the current version of ...
