Pandas Convert Rows to Columns in Python

Question

I have a sample dataset below:

ID	Name	Test	Point
1	Tom	Math	5
1	Tom	Bio	7
2	Jerry	Math	10
2	Jerry	Bio	8
2	Jerry	Data	9

I want to transform grouped dataframe to result below:

ID	Name	Bio	Data
1	Tom	7	NaN
2	Jerry	NaN	9

Below is my code:

# importing pandas as pd
import pandas as pd
import numpy as np

# creating a dataframe
df = pd.DataFrame({
                   'Id': [1,1,2,2,2],
                   'Name': ['Tom', 'Tom', 'Jerry', 'Jerry','Jerry'],
                   'Test': ['Math', 'Bio', 'Math', 'Bio','Data'],
                   'Value': [5, 7, 10, 8, 9]})

df

Grouped

grouped = df.groupby(['Id','Name']).last()
grouped.head()

When I pivot a groupeddataframe raise error. How can I solve this problem?

pivoted = grouped.pivot(index='Name', columns='Test', values='Value')\
            .reset_index()
pivoted.columns.name=None
print(pivoted)

Thanks in advance.
