a= {'平安银行':'000001.XSHE','浦发银行':'600000.XSHG'}
c=a.keys()
print(c)
运行结果可以显示中文，且类型是dict_keys
2019-01-02 09:30:00 - INFO - dict_keys(['平安银行', '浦发银行'])
而非课程运行的结果
b=['\xe5\xb9\xb3\xe5\xae\x89\xe9\x93\xb6\xe8\xa1\x8c', '\xe6\xb5\xa6\xe5\x8f\x91\xe9\x93\xb6\xe8\xa1\x8c']
a= {'平安银行':'000001.XSHE','浦发银行':'600000.XSHG'}
b= {'开盘价':10.0,'收盘价':10.1,'涨跌幅':0.1}
c=a.keys()
print(c)
print(c[0])
运行结果报错
print(c[0])
TypeError: 'dict_keys' object does not support indexing
请教是什么问题？
