pandas raises value error for datetime objects

Question

my dataframe has a datetime index. I can not print its info as it raises a TypeError :

import pandas as pd
from datetime import datetime

df = pd.DataFrame(data={"a": datetime.now()}, index=["a"])
print(df.info())

results in

Traceback (most recent call last):

    print(df.info())

Answer 1

its worked on pandas 1.1.4 so kindly update your pandas package

output of your code:-

<class 'pandas.core.frame.DataFrame'>
Index: 1 entries, a to a
Data columns (total 1 columns):
 #   Column  Non-Null Count  Dtype         
---  ------  --------------  -----         
 0   a       1 non-null      datetime64[ns]
dtypes: datetime64[ns](1)
memory usage: 16.0+ bytes
None
