read_csv header with non-exisiting rows behaving differently · Issue #47400 · pandas-dev/pandas · GitHub

• I have checked that this issue has not already been reported.

• I have confirmed this bug exists on the latest version of pandas.

• I have confirmed this bug exists on the main branch of pandas.

data = """a,b
1,2"""

pd.read_csv(StringIO(data), header=[0, 1, 2], engine="python")

This creates a MultiIndex with 2 levels

While the c engine raises


pandas.errors.ParserError: Passed header=[0,1,2], len of 3, but only 2 lines in file

They should be consistent, since the c engine is more widely used, I would propose adapting the behavior to raise for the python engine. We've deprecated this behavior for usecols and will raise starting with 2.0. We should do something similar here.

Both engines should be consistent

Replace this line with the output of pd.show_versions()
