Import Library but Download first?

[OscarBoots]

Thanks Larz60+, snippsat & buran for your help.

I'm using Anaconda & have found that I have installed pandas & matplotlib.

While practising, with the below code, I found that I have also been able to import them to use.

I do however, get an error about pandas_datareader.

I'm using Python 3.7, is pandas_datareader correct as a library to import??

ModuleNotFoundError: No module named 'pandas_datareader'

import datetime as dt
import matplotlib.pyplot as plt  # shows yellow triangle "Imported but unused"
from matplotlib import style
import pandas as pd              # shows yellow triangle "Imported but unused"
import pandas_datareader.data as web

style.use('ggplot')

start = dt.datetime(2000,1,1)
end = dt.datetime(2016,12,31)

df = web.DataReader('TSLA', 'yahoo', start, end)
print(df.head(4))
