具体的WolframAlpha查询？ [蟒蛇]

Question

http://www.wolframalpha.com/input/?i=1844.8*x%2By%2B0.0084063099220244904*z%3D1844.8,+2538510.9599999995*x%5E2%2B0.38081996307262644*z%5E2%2B2*188.9275870870740*x*z%3D2538510.9599999995,+22.800000000000001*x-0.20000000000000001*y%2B0.54888787955652119*z%3D5

我需要在Python中进行此查询，我尝试过：

import wolframalpha
app_id='XXXXXXX'
client = wolframalpha.Client(app_id)
res = client.query('i=1844.8*x%2By%2B0.0084063099220244904*z%3D1844.8,+2538510.9599999995*x%5E2%2B0.38081996307262644*z%5E2%2B2*188.9275870870740*x*z%3D2538510.9599999995,+22.800000000000001*x-0.20000000000000001*y%2B0.54888787955652119*z%3D5')
for pod in res.pods:
  for sub in pod.subpods:
    print(sub.text)

但它没有成功。我该怎么办？
