QUESTION
I am pretty new to working with jupyter notebook. I overall like it, although I sometimes get some weird errors that sometimes appear and then sometimes do not. For example, I have a data set that looks like this (showing the .head()):
Now, if I set say volume = data["avg_volume"], and then say volume.head() I get this:
But lets say I delete that line and put it somewhere else, I sometimes will get this error:
...ANSWER
Answered 2018-Sep-17 at 18:19In your code for data in pnl
, you redefined the variable data
, so it is no longer a DataFrame
and cannot by indexed by a colum name.
And BTW, many bugs like this can be found out when you are trying to produce a minimal, complete, verifiable example. You'll notice that when you remove the for
loop this bug is gone.
