as pd means that we can reference the pandas module with pd instead of writing out the full pandas each time. We import rand from numpy.random, so that we can populate the DataFrame with random values. In other words, we won't need to manually create the values in the table. The rand...

Depending on the values in the dictionary, we may use this method to rename a single column or many columns. Example Code: importpandasaspd d1={"Names":["Harry","Petter","Daniel","Ron"],"ID":[1,2,3,4]}df=pd.DataFrame(d1)display(df)# rename columnsdf1=df.rename(columns={"Name...
Iterating over rows and columns in a Pandas DataFrame can be done using various methods, but it is generally recommended to avoid explicit iteration whenever possible, as it can be slow and less efficient compared to using vectorized operations offered by Pandas. Instead, try to utilize built-...
