{ 101:'Writing', 102:'stuff', 103:'school', 104:'office' }

Answer 1

You could do the following:

import pandas as pd

df = pd.read_csv("sample.csv")
df.to_dict('records')

You would first import it as a DataFrame from Pandas and then transfrom it into a dict with the argument records . Here you can see how to to_dict works.
