I am making an API call in my flask app:
count = len(bankid)
bankid = "044"
response = requests.get(f"{base_api_url}/banks/" + "{bankid}/branches".format(bankid=f"{{{bankid}:0{count}d}}", headers=headers))
My target is to use this url https://api.flutterwave.com/v3/banks/044/branches. Passing in "044" string only removes the leading zero so trying to use python string formatting to pass in {044:03d}.
This is what I get:
GET /v3/banks/%7B044:03d%7D/branches HTTP/1.1" 401 65]
I want:
GET /v3/banks/044/branches HTTP/1.1" 401 65]
I want python to use "{}" rather than the unicode representation.
There's no point of having bankId a string and then tell fstring to treat it as int just to enforce formatting that would produce it back in the form of original string. You are simply over-complicating the way you construct target URL:
bankid = "044"
response = requests.get(f"{base_api_url}/banks/{bankid}/branches", headers=headers)
EDIT
The bankid has to be an int32 not string and when I pass it as into python strips the leading zero
Then you should have make it clear in your question first. Anyway, the change is trivial, just create string form of bankId as you like prior using it:
bankid = 44
bankIdStr = str(bankId).zfill(3) # change 3 to your liking
response = requests.get(f"{base_api_url}/banks/{bankidStr}/branches", headers=headers)
