Python Pandas. How to extract single column from downloaded yahoo_fin option chain data?

Question

What is the proper way to extract a single column from downloaded option_chain from yahoo_fin? My code for EXXON MOBILE option chains:

from yahoo_fin import options
import pandas as pd
from IPython.display import display, HTML

df = options.get_options_chain("XOM")
pd.set_option('display.max_columns', None) 
display(df)

display_max_columns does not work either.

Anyway I tried doing some numerical and name extractions, but it did not work out at all. any ideas?

Answer 1

The results are stored in a dict with key-value values of the type of option and the corresponding pd.DataFrame. You can get the keys of the dict using keys(). Keys are 'calls' or 'puts'.

from yahoo_fin import options
import pandas as pd

data = options.get_options_chain("XOM")

# access dict by key
calls = data['calls']
puts = data['puts']

calls

Output:

    Contract Name   Last Trade Date Strike  Last Price  Bid Ask Change  % Change    Volume  Open Interest   Implied Volatility
0   XOM220429C00045000  2022-04-21 11:13AM EDT  45.0    43.95   0.00    0.0 0.0 -   -   0   0.00%

To access a single column of the DataFrame use the column name as a key e. g., 'Contract Name'.

calls['Contract Name']

Output:

0     XOM220429C00045000
1     XOM220429C00060000
2     XOM220429C00065000
3     XOM220429C00070000
4     XOM220429C00072000
5     XOM220429C00073000
