python报错 name 'url' is not defined

Question

url = 'https://api.blockchair.com/bitcoin/stats'

r = requests.get(url)
result = json.loads(r.text)
price=(result.get('context').get('market_price_usd'))

系统报错
r = requests.get(url)
NameError: name 'url' is not defined
请问怎么解决呢？

Answer 1

url = 'https://api.blockchair.com/bitcoin/stats'
是写在r = requests.get(url) 前面吗?
是不是url = 'https://api.blockchair.com/bitcoin/stats' 写在了if中没有执行到
把你的完整代码发一下看看
这样测试没有问题

import requests
import json

url = 'https://api.blockchair.com/bitcoin/stats'

r = requests.get(url)
result = json.loads(r.text)
print(result)
