HTTP Question

Python Requests - Dynamically Pass HTTP Verb

Is there a way to pass an HTTP verb (PATCH/POST) to a function and dynamically use that verb for Python requests?

For example, I want this function to take a 'verb' variable which is only called internally and will either = post/patch.

def dnsChange(self, zID, verb):
for record in config.NEW_DNS:
### LINE BELOW IS ALL THAT MATTERS TO THIS QUESTION
json = requests.verb(headers=self.auth, url=self.API + '/zones/' + str(zID) + '/dns_records', data={"type":record[0], "name":record[1], "content":record[2]})
key = record[0] + "record with host " + record[1]
result = json.loads(json.text)
self.apiSuccess(result,key,value)


I realize I cannot requests.'verb' as I have above, it's meant to illustrate the question. Is there a way to do this or something similar? I'd like to avoid an:

if verb == 'post':
json = requests.post(headers=self.auth, url=self.API + '/zones/' + str(zID) + '/dns_records', data={"type":record[0], "name":record[1], "content":record[2]}
else:
json = requests.patch(headers=self.auth, url=self.API + '/zones/' + str(zID) + '/dns_records', data={"type":record[0], "name":record[1], "content":record[2]}


Thanks guys!

Answer

You can always rely on getattr with a default value. Maybe like

action = getattr(requests, verb, None)
if action:
    action(headers=self.auth, url=self.API + '/zones/' + str(zID) + '/dns_records', data={"type":record[0], "name":record[1], "content":record[2]})
else:
    # handle invalid action

For the default value it can be a proper action, or just leave it out and an exception will be raised; it's up to you how you want to handle it. I left it as None so you can deal with alternative case in the else section.
