python global name not defined_python中的“Global name not defined”概念

不用担心：）欢迎来到Python！它抛出这个错误是因为它正在寻找一个不存在的全局变量——而它不存在的原因是因为您没有达到if type == "accounts"条件！

试试这个：for i in included:

global signs,accounts, regions

global sign_name, acc_name, rg_name

regions = "no region yet"

acc_name = "no acc_name yet"

if type == "regions"

regions = i

rg_name = regions['data']['region']

if type == "accounts"

accounts = i

acc_name = accounts['data']['account']

print("Stopping account " + acc_name + " in region " + rg_name)

这将清除错误，至少让您看到可能出现的其他错误：）

我还将指出，我相信您会从其他人那里听到，您没有理由在这个上下文中声明全局变量。它最初的意思是“找不到全局变量”，因为在您输入global关键字之前，它没有触发if语句，因此它首先检查locals()变量，没有找到它，搜索globals()变量，没有发现它被踢出并出错。

您可以删除global变量，它的工作原理如下：for i in included:

regions = "no region yet"

acc_name = "no acc_name yet"

if type == "regions"

regions = i

rg_name = regions['data']['region']

if type == "accounts"

accounts = i

acc_name = accounts['data']['account']

print("Stopping account " + acc_name + " in region " + rg_name)

另一个简短的提示，永远不要将type作为变量。。。改用type_。原因是type是一个builtinPython函数，如果使用type作为变量，则会意外地给该内置名称起别名。

最后，再把剧本整理一下：# only use "i" when you're using numbers, otherwise just call it

# the name of the data you're using :)

for account_data in included:

regions = "no region yet"

acc_name = "no acc_name yet"

if type_ == "regions"

rg_name = account_data['data']['region']

if type_ == "accounts"

acc_name = account_data['data']['account']

# here's an example of Pythonic string formatting :)

print("Stopping account {} in region {}".format(acc_name, rg_name))
