Check if a value exists in pandas dataframe index

Question

I am sure there is an obvious way to do this but cant think of anything slick right now.

Basically instead of raising exception I would like to get True

Answer 1

df = pandas.DataFrame({'g':[1]}, index=['isStop'])

#df.loc['g']

if 'g' in df.index:
    print("find g")

if 'isStop' in df.index:
    print("find a")
