Create Google Cloud Function using API in Python

I'm working on a project with Python(3.6) & Django(1.10) in which I need to create a function at Google cloud using API request.

How can upload code in the form of a zip archive while creating that function?

Here's what I have tried:

From views.py :

    def post(self, request, *args, **kwargs):
    if request.method == 'POST':
        post_data = request.POST.copy()
        post_data.update({'user': request.user.pk})
        form = forms.SlsForm(post_data, request.FILES)
        print('get post request')
        if form.is_valid():
            func_obj = form
            func_obj.user = request.user
            func_obj.project = form.cleaned_data['project']
            func_obj.fname = form.cleaned_data['fname']
            func_obj.fmemory = form.cleaned_data['fmemory']
            func_obj.entryPoint = form.cleaned_data['entryPoint']
            func_obj.sourceFile = form.cleaned_data['sourceFile']
            func_obj.sc_github = form.cleaned_data['sc_github']
            func_obj.sc_inline_index = form.cleaned_data['sc_inline_index']
            func_obj.sc_inline_package = form.cleaned_data['sc_inline_package']
            func_obj.bucket = form.cleaned_data['bucket']
            func_obj.save()
            service = discovery.build('cloudfunctions', 'v1', http=views.getauth(), cache_discovery=False)
            requ = service.projects().locations().functions().generateUploadUrl(parent='projects/' + func_obj.project + '/locations/us-central1', body={})
            resp = requ.execute()
            print(resp)
            try:
                auth = views.getauth()
                # Prepare Request Body
                req_body = {
                    "CloudFunction": {
                        "name": func_obj.fname,
                        "entryPoint": func_obj.entryPoint,
                        "timeout": '60s',
                        "availableMemoryMb": func_obj.fmemory,
                        "sourceArchiveUrl": func_obj.sc_github,
                    },
                    "sourceUploadUrl": func_obj.bucket,
                }
                service = discovery.build('cloudfunctions', 'v1beta2', http=auth, cachce_dicovery=False)
                func_req = service.projects().locations().functions().create(location='projects/' + func_obj.project
                                                                                      + '/locations/-',
                                                                             body=req_body)
                func_res = func_req.execute()
                print(func_res)
                return HttpResponse('Submitted',)
            except:
                return HttpResponse(status=500)

        return HttpResponse('Sent!')

Updated Code below:

            if form.is_valid():
            func_obj = form
            func_obj.user = request.user
            func_obj.project = form.cleaned_data['project']
            func_obj.fname = form.cleaned_data['fname']
            func_obj.fmemory = form.cleaned_data['fmemory']
            func_obj.entryPoint = form.cleaned_data['entryPoint']
            func_obj.sourceFile = form.cleaned_data['sourceFile']
            func_obj.sc_github = form.cleaned_data['sc_github']
            func_obj.sc_inline_index = form.cleaned_data['sc_inline_index']
            func_obj.sc_inline_package = form.cleaned_data['sc_inline_package']
            func_obj.bucket = form.cleaned_data['bucket']
            func_obj.save()

            file_name = os.path.join(IGui.settings.BASE_DIR, 'media/archives/', func_obj.sourceFile.name)
            print(file_name)

            service = discovery.build('cloudfunctions', 'v1')
            func_api = service.projects().locations().functions()
            url_svc_req = func_api.generateUploadUrl(parent='projects/'
                                                            + func_obj.project
                                                            + '/locations/us-central1',
                                                     body={})
            url_svc_res = url_svc_req.execute()
            print(url_svc_res)

            upload_url = url_svc_res['uploadUrl']
            print(upload_url)
            headers = {
                'content-type': 'application/zip',
                'x-goog-content-length-range': '0,104857600'
            }
            print(requests.put(upload_url, headers=headers, data=func_obj.sourceFile.name))
            auth = views.getauth()
            # Prepare Request Body
            name = "projects/{}/locations/us-central1/functions/{}".format(func_obj.project, func_obj.fname,)
            print(name)
            req_body = {
              "name": name,
              "entryPoint": func_obj.entryPoint,
              "timeout": "3.5s",
              "availableMemoryMb": func_obj.fmemory,
              "sourceUploadUrl": upload_url,
              "httpsTrigger": {},
            }
            service = discovery.build('cloudfunctions', 'v1')
            func_api = service.projects().locations().functions()

            response = func_api.create(location='projects/' + func_obj.project + '/locations/us-central1',
                                                body=req_body).execute()

            pprint.pprint(response)

Now the function has been created successfully, but it fails because the source code doesn't upload to storage bucket, that's maybe something wrong at:

upload_url = url_svc_res['uploadUrl']
            print(upload_url)
            headers = {
                'content-type': 'application/zip',
                'x-goog-content-length-range': '0,104857600'
            }
            print(requests.put(upload_url, headers=headers, data=func_obj.sourceFile.name))
