Pandas is a powerful python library to analyze and manipulate data. By default data frame's index starts with 0, which I don't like so much. Let's start the index with 1.
import pandas
data=[{'name': 'alex', 'age': 30}, {'name': 'manny', 'age': 32}, {'name': 'mike', 'age': 29}]
df=pandas.DataFrame(data)
df.sort_values('age',inplace=True)
df.reset_index(drop=True,inplace=True)
df.index+=1
print(df)
python3.8 /tmp/pd.py
name age
1 mike 29
2 alex 30
3 manny 32
