For online django projects and routing functions, global variables are declared with global, but an error is reported when it is used.

for example: multiple routing functions declare the global variable login, in global, and sometimes the following error occurs! There is to import variables from an app inside the function, the value has not changed!
NameError: name "login" is not defined
