Aggregate a column

DataFrames can calculate aggregations on columns. Aggregation functions such as mean, max, min, and std are available.

Using the same DataFrame from before,

import pandas as pd

df = pd.DataFrame({'name': ['Jeff', 'Esha', 'Jia'], 
                   'age': [30, 56, 8]})
name age
1 Jeff 30
2 Esha 56
3 Jia 8

What is the minimum value of age? Define a variable min_age with the value of df.age.min() would output.
