The error message “read_csv() got an unexpected keyword argument 'on_bad_lines'” in Python occurs when the function read_csv() is called with an invalid or unrecognized argument.
This error typically happens when you are using an outdated version of the pandas library, as the 'on_bad_lines' argument was introduced in later versions.
To fix this issue, you can either update your pandas library to the latest version or remove the 'on_bad_lines' argument from your call to read_csv().
Examples:
# Example 1: Outdated pandas version
import pandas as pd
data = pd.read_csv('data.csv', on_bad_lines=True) # This line will throw the mentioned error
# To fix this, either update pandas or remove 'on_bad_lines' argument
# Option 1: Update pandas (recommended)
# Option 2: Remove 'on_bad_lines' argument
data = pd.read_csv('data.csv')# Example 2: Removing 'on_bad_lines' argument
import pandas as pd
data = pd.read_csv('data.csv', on_bad_lines=True) # This line will throw the error
# Remove 'on_bad_lines' argument
data = pd.read_csv('data.csv')
