Lets say you want to download a PDF file from a website, and want to save at your PC. Instead of "w" write mode, you have to use "wb" mode. Means write as binary mode. So the code will be.
localFile = open("my_pdf.pdf", 'wb')
Similarly while reading the binary file, just use "wb" to read a file. Anyway here I'm giving a code that will help you to download a PDF file from a website. You can use any link of .doc, .xls, .gif, .jpg or any type. Just call the function with your url, and file name.
from urllib2 import urlopen
def downloadPDF(url, outfile):
webFile = urlopen(url)
localFile = open(outfile, 'wb')
except IOError, e:
print "Download error"
