how to deal with no column names when reading a csv in python in python

To read a CSV file in Python using Pandas when there are no column names provided, use the header parameter as None. The following code snippet demonstrates how to read a CSV file with no column names:

main.py
import pandas as pd

df = pd.read_csv('filename.csv', header=None)
67 chars
4 lines

Setting header to None will tell Pandas to use default integer column names (0, 1, 2, ...) for the DataFrame.
