I have been recently trying to make a program in python that downloads files to a specific directory. I am using Ubuntu and so far i have this
import os
import getpass
import urllib2
y = getpass.getuser()
if not os.access('/home/' + y + '/newdir/', os.F_OK):
print("Making New Directory")
os.mkdir('/home/' + y + '/newdir/')
url = ("http://example.com/Examplefile.ex")
file_name = url.split('/')[-1]
u = urllib2.urlopen(url)
f = open(file_name, 'wb')
meta = u.info()
file_size = int(meta.getheaders("Content-Length")[0])
print "Downloading: %s Bytes: %s" % (file_name, file_size)
file_size_dl = 0
block_sz = 8192
while True:
buffer = u.read(block_sz)
if not buffer:
break
file_size_dl += len(buffer)
f.write(buffer)
status = r"%10d [%3.2f%%]" % (file_size_dl, file_size_dl * 100. / file_size)
status = status + chr(8)*(len(status)+1)
print status,
f.close()
this currently downloads the file to the same directory how could I change the directory it downloads to?
fixed it new code:
import os
import getpass
import urllib2
y = getpass.getuser()
if not os.access('/home/' + y + '/newdir/', os.F_OK):
print("Making New Directory")
os.mkdir('/home/' + y + '/newdir/')
os.chdir('/home/'+y+'/newdir/')
url = ("http://example.com/Examplefile.ex")
file_name = url.split('/')[-1]
u = urllib2.urlopen(url)
f = open(file_name, 'wb')
meta = u.info()
file_size = int(meta.getheaders("Content-Length")[0])
print "Downloading: %s Bytes: %s" % (file_name, file_size)
file_size_dl = 0
block_sz = 8192
while True:
buffer = u.read(block_sz)
if not buffer:
break
file_size_dl += len(buffer)
f.write(buffer)
status = r"%10d [%3.2f%%]" % (file_size_dl, file_size_dl * 100. / file_size)
status = status + chr(8)*(len(status)+1)
print status,
f.close()
Sorry Guys I was Being stupid but to Answer the Question I added
os.chdir('/home/' + y + '/newdir/')
right after the first if statement ex:
import os
import getpass
import urllib2
y = getpass.getuser()
if not os.access('/home/' + y + '/newdir/', os.F_OK):
print("Making New Directory")
os.mkdir('/home/' + y + '/newdir/')
os.chdir('/home/'+y+'/newdir/')
url = ("http://example.com/Examplefile.ex")
file_name = url.split('/')[-1]
u = urllib2.urlopen(url)
f = open(file_name, 'wb')
meta = u.info()
file_size = int(meta.getheaders("Content-Length")[0])
print "Downloading: %s Bytes: %s" % (file_name, file_size)
file_size_dl = 0
block_sz = 8192
while True:
buffer = u.read(block_sz)
if not buffer:
break
file_size_dl += len(buffer)
f.write(buffer)
status = r"%10d [%3.2f%%]" % (file_size_dl, file_size_dl * 100. / file_size)
status = status + chr(8)*(len(status)+1)
print status,
f.close()
Pass the directory to open()
in the filename.
Use os.path.join to add the directory to file_name
:
from os.path import join
directory = join('/home/', y, '/newdir/')
# You can now use directory everywhere you used to build the directory name
# and then, later in the script:
file_name = url.split('/')[-1]
file_name = join(directory, file_name)
