[python] Pandas read_csv from url

I'm trying to read a csv-file from given URL, using Python 3.x:

import pandas as pd
import requests

url = "https://github.com/cs109/2014_data/blob/master/countries.csv"
s = requests.get(url).content
c = pd.read_csv(s)

I have the following error

"Expected file path name or file-like object, got <class 'bytes'> type"

How can I fix this? I'm using Python 3.4

This question is related to python csv pandas request

The answer is


In the latest version of pandas (0.19.2) you can directly pass the url

import pandas as pd

url="https://raw.githubusercontent.com/cs109/2014_data/master/countries.csv"
c=pd.read_csv(url)

As I commented you need to use a StringIO object and decode i.e c=pd.read_csv(io.StringIO(s.decode("utf-8"))) if using requests, you need to decode as .content returns bytes if you used .text you would just need to pass s as is s = requests.get(url).text c = pd.read_csv(StringIO(s)).

A simpler approach is to pass the correct url of the raw data directly to read_csv, you don't have to pass a file like object, you can pass a url so you don't need requests at all:

c = pd.read_csv("https://raw.githubusercontent.com/cs109/2014_data/master/countries.csv")

print(c)

Output:

                              Country         Region
0                             Algeria         AFRICA
1                              Angola         AFRICA
2                               Benin         AFRICA
3                            Botswana         AFRICA
4                             Burkina         AFRICA
5                             Burundi         AFRICA
6                            Cameroon         AFRICA

From the docs:

filepath_or_buffer :

string or file handle / StringIO The string could be a URL. Valid URL schemes include http, ftp, s3, and file. For file URLs, a host is expected. For instance, a local file could be file ://localhost/path/to/table.csv


url = "https://github.com/cs109/2014_data/blob/master/countries.csv"
c = pd.read_csv(url, sep = "\t")

The problem you're having is that the output you get into the variable 's' is not a csv, but a html file. In order to get the raw csv, you have to modify the url to:

'https://raw.githubusercontent.com/cs109/2014_data/master/countries.csv'

Your second problem is that read_csv expects a file name, we can solve this by using StringIO from io module. Third problem is that request.get(url).content delivers a byte stream, we can solve this using the request.get(url).text instead.

End result is this code:

from io import StringIO

import pandas as pd
import requests
url='https://raw.githubusercontent.com/cs109/2014_data/master/countries.csv'
s=requests.get(url).text

c=pd.read_csv(StringIO(s))

output:

>>> c.head()
    Country  Region
0   Algeria  AFRICA
1    Angola  AFRICA
2     Benin  AFRICA
3  Botswana  AFRICA
4   Burkina  AFRICA

To Import Data through URL in pandas just apply the simple below code it works actually better.

import pandas as pd
train = pd.read_table("https://urlandfile.com/dataset.csv")
train.head()

If you are having issues with a raw data then just put 'r' before URL

import pandas as pd
train = pd.read_table(r"https://urlandfile.com/dataset.csv")
train.head()
