TypeError: strptime() argument 1 must be str, not Series

This error occurs when you try to pass a Pandas Series object as the argument for the strptime() method. The strptime() method is used to convert a string into a date object, but it requires a string as input, not a Series object.

To resolve this error, you can convert the Series object into a string before passing it to the strptime() method. You can do this using the .astype() method, which allows you to convert the data type of a Pandas Series.

For example:

import pandas as pd
from datetime import datetime

# create a sample Series object
dates = pd.Series(['2022-01-01', '2022-01-02', '2022-01-03'])

# convert the Series to a string using .astype()
date_str = dates.astype(str)

# use strptime() to convert the string to a date object
date_obj = datetime.strptime(date_str, '%Y-%m-%d')

In this example, we first convert the dates Series object to a string using the .astype() method. We then pass the resulting string to the strptime() method to convert it into a date object.
