‘series’ object has no attribute ‘columns’

by

Explanation:

The error message “AttributeError: ‘series’ object has no attribute ‘columns'” is raised when you try to access the ‘columns’ attribute of a pandas Series object. This error typically occurs when you mistakenly treat a single-dimensional pandas Series as a DataFrame, which has ‘columns’ as one of its attributes.

Example:

import pandas as pd

# Create a pandas Series
s = pd.Series([1, 2, 3, 4, 5])

# Attempting to access 'columns' attribute of a Series
s.columns # This will raise the 'AttributeError'

# To access columns, use the 'columns' attribute with DataFrame objects
df = pd.DataFrame({'A': [1, 2, 3], 'B': [4, 5, 6]})
print(df.columns) # This will print the column names of the DataFrame
