在python中一旦退出循环就会丢失dict内容

Question

需要一些帮助..。子:一旦退出循环，就会丢失数据内容。dict使用循环vars填充，这些循环vars使用下标方法添加到dict中。下面的foo()总是被执行，因为team_oncall_dict在外部是空的。任何提示，我怎么能保留它，因为它是在循环内？

    if not team_oncall_dict: #part of func def
       do foo()

输出

foo stuff

示例数据是一组数据集。

[{'escalation_policy': {'id': 'P8RKTEE', 'type': 'escalation_policy_reference', 'summary': 'Team Escalation Policy'}, 'escalation_level': 3, 'schedule': None, 'user': {'id': 'PX8XYFT', 'type': 'user_reference', 'summary': 'M1’}, 'start': None, 'end': None}, 
{'escalation_policy': {'id': 'P8RKTEE', 'type': 'escalation_policy_reference', 'summary': 'Team Escalation Policy'}, 'escalation_level': 1, 'schedule': None, 'user': {'id': 'PKXXVJI', 'type': 'user_reference', 'summary': ‘R1’}, 'start': None, 'end': None}, 
{'escalation_policy': {'id': 'P8RKTEE', 'type': 'escalation_policy_reference', 'summary': 'Team’}, 'escalation_level': 2, 'schedule': None, 'user': {'d': 'PN8F9PC', 'type': 'user_reference’,'summary': ‘T1’}],'start': None, 'end': None}]

顺便说一句:上面是第四个内环。所以流就像这样。

def func1()
team_oncall_dict = {}

  loop1
     loop2
        loop3
           loop4
             ...
             team_oncall_dict
   if not team_oncall_dict:
     print("dict is empty")

输出

dict is empty

Answer 1

T是地方性的，而不是全球性的。通过在函数之外全局声明team_oncall_dict来修正它。

结束符

def func1()
team_oncall_dict = {}

team_oncall_dict = {}
def func1()
