Hi,
I am trying to read a CSV file from memory. Basically, what
I am trying to do is - I am downloading a CSV file from a
web site, and trying to parse it through CSV module,
without saving it to disk. However, CSV behaves in a
different way. For example:
import csv, urllib
url="http://......./xxxxx.csv"
webFile = urllib.urlopen(url)
localFile = open(fname, 'w')
localFile.write(webFile.read())
webFile.close()
localFile.close()
csvReader=csv.reader(open(fname))
for row in csvReader:
print row
#gives output as:
#['-2.0000e-03', '-0.0002']
#.......
Same thing, slightly different:
import csv, urllib
url="http://......./xxxxx.csv"
webFile = urllib.urlopen(url)
csvReader=csv.reader(open(webFile.read()))
webFile.close()
for row in csvReader:
print row
#gives output:
#['-']
#....
How can I get rid of this behaviour?
