Description
Pandas version checks
-
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.
Reproducible Example
import pandas as pd
test = ['test.csv']
pd.read_csv(test)Issue Description
Running this code results in an immediate segfault. Specifying engine = 'python' does not, so presumably bad data is passed to the C engine. If test is a dict, set, or numpy.ndarray, a ValueError is raised as expected.
We discovered this error in a Snakemake rule, where the user passed input, which by default a list, directly to read_csv in a run block. Given Snakemake's popularity, this seems like something that could pop up fairly often.
Expected Behavior
It should raise a ValueError.
Installed Versions
My environment seems to break with this.
