Question

我正在使用将json列表与python文件中的列表进行比较的代码，但是for循环即时消息使用的类型会返回TypeError：“函数”对象不可迭代。我不确定该如何解决

我尝试将“乘员中的k2：”更改为“乘员中的k2 ：(）：”和“乘员中k2：[：]：”），但是每一个都有问题

url = 'http://api.open-notify.org/astros.json'
response = urllib.request.urlopen(url)
result = json.loads(response.read())
people = result["people"]
people_with_exist_state = []

occupants = [

@app.route("/occupants")
def occupants():
 for k in people:
  is_here = 0
  for k2 in occupants:
    if k['name'] == k2['name']:
      is_here = 1
  if is_here == 0:
     #name does not exist
     k['exist'] = 0
  else:
     # name exist
     k['exist'] = 1
  people_with_exist_state.append(k)
 return render_template('occupants.html', people=people_with_exist_state)

Answer 1

假设people和occupants是代码中的全局变量，则不能像命名变量def occupants():那样命名函数occupants

如何使_ in _在函数中起作用
