Valueerror: a given column is not a column of the dataframe

ValueError: A given column is not a column of the dataframe

This error occurs when you try to access or perform an operation on a column in a DataFrame that doesn’t exist.

Here’s an example to better understand this error:

    
      import pandas as pd
      
      # Create a DataFrame
      df = pd.DataFrame({'A': [1, 2, 3], 'B': [4, 5, 6]})
      
      # Try to access a non-existing column
      df['C']  # This will raise a ValueError
      
      # Output:
      # ValueError: A given column is not a column of the dataframe
    
  

In the above example, we created a DataFrame with columns ‘A’ and ‘B’. However, when we tried to access column ‘C’, it raised a ValueError because ‘C’ is not a column in the DataFrame.

To avoid this error, make sure you are accessing the correct column name from the DataFrame. Double-check the column names and verify their existence before accessing or performing any operations on them.
