Pandas没有进口吗名称错误：未定义全局名称“pandas”

Question

我这里有一些错误，但我认为是因为熊猫没有进口，因为它是灰色的。如果是这个问题，我该怎么解决？

C:\Anaconda\python.exe C:/Users/nickd/Documents/SKLEARN-STOCKS/stock-mach.py Traceback (most recent call last): File "C:/Users/nickd/Documents/SKLEARN-STOCKS/stock-mach.py", line 38, in Key_Stats() File "C:/Users/nickd/Documents/SKLEARN-STOCKS/stock-mach.py", line 12, in Key_Stats df = pandas.DataFrame(columns = ['Date','Unix','Ticker','DE Ratio']) NameError: global name 'pandas' is not defined

Answer 1

你已经把它作为

import pandas as pd

打电话来

#pandas
df = pandas.DataFrame(columns = ['Date','Unix','Ticker','DE Ratio'])

你要么改变

• import pandas as pd到import pandas或
• df = pandas.DataFrame(columns = ['Date','Unix','Ticker','DE Ratio'])到df = pd.DataFrame(columns = ['Date','Unix','Ticker','DE Ratio'])。

编辑：

错误是由于缺少)

save = gather.replace(' ','').replace(')','').replace('(','').replace('/',''+('.csv'))

Answer 2

您将熊猫作为pd导入。请始终以这种方式引用它，或者从导入中移除as pd。

（另外，永远不会做except Exception... pass。你会吞下所有的错误，永远不知道它们是什么。如果你不打算处理它们，就不要抓住它们。）
