变量已分配，但返回"Name Error"

Question

result = adfuller(df["Milk, lbs/cow"])
def adf_check(time_series):
result = adfuller(time_series)
print("Augmented Dickey Fuller Test")
labe = ['ADF Test Statistic', 'p-value', '# of lags', '# of Observations']
for value, label in zip (result, labe):
print(label+ ' : ' + str(value))

我收到此错误，因为变量已明确定义。有什么原因没有运行吗？

NameError

NameError: name 'labe' is not defined

Answer 1

result = adfuller(df["Milk, lbs/cow"])
def adf_check(time_series):
result = adfuller(time_series)
print("Augmented Dickey Fuller Test")
labe = ['ADF Test Statistic', 'p-value', '# of lags', '# of Observations']
# indentation matters in python
for value, label in zip (result, labe):
print(label+ ' : ' + str(value))
