This might be easier than using requests  This is the only time I ll ever suggest not using requests to do HTTP stuff   Two liner using urllib    gt  gt  gt  import urllib  gt  gt  gt  urllib request urlretrieve  http   www example com songs mp3 mp3    mp3 mp3       There is also a nice Python module named wget that is pretty easy to use  Found here   This demonstrates the simplicity of the design    gt  gt  gt  import wget  gt  gt  gt  url    http   www futurecrew com skaven song files mp3 razorback mp3   gt  gt  gt  filename   wget download url  100                                                     3841532   3841532 gt   gt  gt  filename  razorback mp3    Enjoy   Edit  You can also add an out parameter to specify a path    gt  gt  gt  out filepath    lt output filepath gt       gt  gt  gt  filename   wget download url  out out filepath

There are 2 main ways    Using  content  simplest official   see Zhenyi Zhang s answer    import io    Note  io BytesIO is StringIO StringIO on Python2  import requests  r   requests get  http   lorempixel com 400 200   r raise for status   with io BytesIO r content  as f      with Image open f  as img          img show    Using  raw  see Martijn Pieters s answer    import requests  r   requests get  http   lorempixel com 400 200   stream True  r raise for status   r raw decode content   True    Required to decompress gzip deflate compressed responses  with PIL Image open r raw  as img      img show   r close      Safety when stream True ensure the connection is released     Timing both shows no noticeable difference

You can do something like this   import requests import random  url    https   images pexels com photos 1308881 pexels-photo-1308881 jpeg  auto compress amp cs tinysrgb amp dpr 1 amp w 500  name random randrange 1 1000  filename str name    jpg  response   requests get url  if response status code ok     with open filename  w   as f      f write response content

I have the same need for downloading images using requests  I first tried the answer of Martijn Pieters  and it works well  But when I did a profile on this simple function  I found that it uses so many function calls compared to urllib and urllib2    I then tried the way recommended by the author of requests module    import requests from PIL import Image   python2 x  use this instead     from StringIO import StringIO   for python3 x  from io import StringIO  r   requests get  https   example com image jpg   i   Image open StringIO r content     This much more reduced the number of function calls  thus speeded up my application  Here is the code of my profiler and the result      usr bin python import requests from StringIO import StringIO from PIL import Image import profile  def testRequest        image name    test1 jpg      url    http   example com image jpg       r   requests get url  stream True      with open image name   wb   as f          for chunk in r iter content                f write chunk   def testRequest2        image name    test2 jpg      url    http   example com image jpg       r   requests get url       i   Image open StringIO r content       i save image name   if   name         main         profile run  testUrllib         profile run  testUrllib2         profile run  testRequest       The result for testRequest   343080 function calls  343068 primitive calls  in 2 580 seconds   And the result for testRequest2   3129 function calls  3105 primitive calls  in 0 024 seconds

my approach was to use response content  blob  and save to the file in binary mode img blob   requests get url  timeout 5  content      with open destination         title   wb   as img file           img file write img blob   Check out my python project that downloads images from unsplash com based on keywords

Get a file-like object from the request and copy it to a file  This will also avoid reading the whole thing into memory at once   import shutil  import requests  url    http   example com img png  response   requests get url  stream True  with open  img png    wb   as out file      shutil copyfileobj response raw  out file  del response

You can either use the response raw file object  or iterate over the response   To use the response raw file-like object will not  by default  decode compressed responses  with GZIP or deflate   You can force it to decompress for you anyway by setting the decode content attribute to True  requests sets it to False to control decoding itself   You can then use shutil copyfileobj   to have Python stream the data to a file object   import requests import shutil  r   requests get settings STATICMAP URL format   data   stream True  if r status code    200      with open path   wb   as f          r raw decode content   True         shutil copyfileobj r raw  f            To iterate over the response use a loop  iterating like this ensures that data is decompressed by this stage   r   requests get settings STATICMAP URL format   data   stream True  if r status code    200      with open path   wb   as f          for chunk in r              f write chunk    This ll read the data in 128 byte chunks  if you feel another chunk size works better  use the Response iter content   method with a custom chunk size   r   requests get settings STATICMAP URL format   data   stream True  if r status code    200      with open path   wb   as f          for chunk in r iter content 1024               f write chunk    Note that you need to open the destination file in binary mode to ensure python doesn t try and translate newlines for you  We also set stream True so that requests doesn t download the whole image into memory first

This is how I did it  import requests from PIL import Image from io import BytesIO  url    your url  files     file     C  Users shadow Downloads black jpeg   open  C  Users shadow Downloads black jpeg    rb    image jpg    response   requests post url  files files   img   Image open BytesIO response content   img show

Here is a more user-friendly answer that still uses streaming    Just define these functions and call getImage    It will use the same file name as the url and write to the current directory by default  but both can be changed   import requests from StringIO import StringIO from PIL import Image  def createFilename url  name  folder       dotSplit   url split          if name    None            use the same as the url         slashSplit   dotSplit -2  split              name   slashSplit -1      ext   dotSplit -1      file             format folder  name  ext      return file  def getImage url  name None  folder            file   createFilename url  name  folder      with open file   wb   as f          r   requests get url  stream True          for block in r iter content 1024               if not block                  break             f write block   def getImageFast url  name None  folder            file   createFilename url  name  folder      r   requests get url      i   Image open StringIO r content       i save file   if   name         main           Uses Less Memory     getImage  http   www example com image jpg         Faster     getImageFast  http   www example com image jpg     The request guts of getImage   are based on the answer here and the guts of getImageFast   are based on the answer above

This is the first response that comes up for google searches on how to download a binary file with requests  In case you need to download an arbitrary file with requests  you can use   import requests url    https   s3 amazonaws com lab-data-collections GoogleNews-vectors-negative300 bin gz  open  GoogleNews-vectors-negative300 bin gz    wb   write requests get url  allow redirects True  content
