Problem:
You are trying to initialize a Python requests session using a custom set of HTTP headers like this:
s = requests.Session(headers={ "User-Agent": "Mozilla/5.0 (Windows NT 6.2; WOW64; rv:34.0) Gecko/20100101 Firefox/34.0" })
but you only see this stacktrace:
File "RequestsSession.py", line 30, in translate "User-Agent": "Mozilla/5.0 (Windows NT 6.2; WOW64; rv:34.0) Gecko/20100101 Firefox/34.0" TypeError: __init__() got an unexpected keyword argument 'headers'
Solution:
You can’t use the headers=...
argument in the requests.Session(...)
constructor.
Use s.headers.update({...})
instead:
s = requests.Session() s.headers.update({ "User-Agent": "Mozilla/5.0 (Windows NT 6.2; WOW64; rv:34.0) Gecko/20100101 Firefox/34.0" })
