UnboundLocalError: local variable 'df' referenced before assignment

See original GitHub issue

Which version are you running? The lastest version is on Github. Pip is for major releases.

import pandas_ta as ta
print(ta.version)

I'm running version 0.3.14b0

Description of the bug I keep getting an UnboundedLocalError saying local variable ‘df’ referenced before assignment. The piece of code is below:

To Reproduce

import pandas as pd
import pandas_ta as ta

df = pd.DataFrame()

tesla = df.ta.ticker('tsla', period='3mo')

Expected behavior I expected to get a dataframe object with a 3 month historical data for the Tesla stock

@twopirllc

I restarted VS Code and tried to reproduce the bug without the line of code you suggested and it worked. I tried it again and it still worked. It’s kind of strange.

I have added the line of code now and it still works.

Cheers!

@enoch-prince,

Awesome! I appreciate you responding promptly and the temporary fix solves the UnboundLocalError issue. I will add the fix for the next version so it does not occur again.

Thank you, KJ
