Question

>>> import pandas as pd
>>> dFrameEmt = pd.DataFrame()
>>> dFrameEmt
Empty DataFrame
Columns: []
Index: []

What would happen if we pass 3 columns or 5 columns instead of 4 in the above code? What is the reason?

Answer 1

• In the given code, if we pass 3 columns or 5 columns instead of 4, an error will occur because the DataFrame does not have matching column labels.
• The number of column names must be equal to the number of columns in the DataFrame. If the numbers do not match, Pandas cannot create the DataFrame properly.
