Python : Event Based Sequence depended on Each other-CodePudding

I have a sequence of request calls dependent on each other, each one searches on a field in DB or Scrape a website, the sequence stops when a request finds the item

I am using a sequence of if statement pseudo code

if found: 
   return 
else:
   call_request(params1)

if found: 
   return 
else:
   call_second_request(params2)

I am looking for an optimized way to do this sequence of request calls

CodePudding user response：

You can put the request functions inside a list and use a for loop:

request_funcs = [call_request, call_second_request, ...]

for func in request_funcs:
    result = func()
    if result:
        return
print("Not found")

If it's the same function, use a while loop:

found = False
while not found:
    found = call_next_request()
return
