numba 加速 Python for循环

用numba来加速Python 循环执行不下去{:5_107:} ，求大神指点一二~

#代码
@nb.jit()
def nb1():
    for i in range(len(df1)):
      if df1.iloc['首3邮编'] < '350':
            df1['落地点'].at = 'JFK'
      elif df1.iloc['首3邮编'] >= '790':
            df1['落地点'].at = 'LAX'
      else:
            df1['落地点'].at = 'ORD'


nb1()

# error

@nb.jit()

你这个是啥？ 装饰器的话，也没看到你引入包啊？ 是你自己在逗自己玩，还是别人在逗你玩？
