Pandas: Time-series with two index labels and random values

Pandas Time Series: Exercise-5 with Solution

Write a Pandas program to create a time-series with two index labels and random values. Also print the type of the index.

Sample Solution:

Python Code :

import pandas as pd
import numpy as np
import datetime
from datetime import datetime, date
dates = [datetime(2011, 9, 1), datetime(2011, 9, 2)]
print("Time-series with two index labels:")
time_series = pd.Series(np.random.randn(2), dates)
print("\nType of the index:")

Sample Output:

Time-series with two index labels:
2011-09-01   -0.257567
2011-09-02    0.947341
dtype: float64

Type of the index:
<class 'pandas.core.indexes.datetimes.DatetimeIndex'>
