Unable to import Pandas_Datareader

Question

I'm using Python 3.6 in Ubuntu 16.04.

From this very simple program:

import pandas_datareader.data as web
import datetime
amzn = web.DataReader("AMZN", "yahoo", datetime(2000,1,1), datetime(2015,1,1))

I get this very impressive error list:

 Traceback (most recent call last):

SyntaxError: invalid syntax

I've really now idea what is causing this error other than it's occurring when the program tries to import pandas_datareader.

I am new to the data_reader but I'm pretty sure the import command is syntactically correct.

Can anyone suggest what the problem is?

Answer 1

I think you have shadowed Python module argparse with your own /SAT/argparse.py .

/anaconda/lib/python3.6/unittest/main.py in line 4 tries to import argparse (the standard Python module), but your module (which has an error len(sys.argv) > 1: ) jumps in first.

Try to rename /SAT/argparse.py to /SAT/my_argparse.py

PS try to name your own scripts and directories differently so that they don't shadow stardard Python modules

Answer 2

Try this:

import datetime

import pandas_datareader.data as web

amzn = web.DataReader("AMZN", "yahoo", datetime.datetime(2000,1,1), datetime.datetime(2015,1,1))
