Here's my view

def ATFinfo(Request):
    # inputdata = Request.GET.get('inputdata')
    url = 'www.google.com'
    req = Request.GET
    print("hi",req)
    req_list = list(dict(req).values())
    print("list",req_list)
    params_count = len(req_list)
    print('params_count', params_count)
    if params_count > 0:
        for i in range(params_count):
            params = params   req_list[i 1][0]   '='   req_list[i 1][1]   '&' 
        url = url   params

        print('paramfinal',params)
    return render(Request, 'hello/ATF_Dashboard.html')

In this view i'm getting error local variable 'params' referenced before assignment in line params = params req_list[i 1][0] '=' req_list[i 1][1] '&' How to solve that issue? Also i'm not able to understand what is the problem here

CodePudding user response：

When you tried to use params here specifically the expression params req_list..., the variable params isn't defined yet.

for i in range(params_count):
    params = params   req_list[i 1][0]   '='   req_list[i 1][1]   '&' 

You have to define it first:

params = ""
for i in range(params_count):
    params = params   req_list[i 1][0]   '='   req_list[i 1][1]   '&'

You could also use = operator:

params  = req_list[i 1][0]   '='   req_list[i 1][1]   '&'

Also based on the pasted code, take note that this line:

url = url   params

Doesn't add anything in the logic as url isn't used after that (unless the pasted code is not the complete version).
