pandas: can we look for the index of a string

[paul18fr]

Dear All

For the first time I'm trying to use Pandas to load and read csv files that inlude values and strings; DataFrames object is quite new for me and I'm still trying to understand its specificities.

I'm wondering if I can look for strings (and to get the row indexes for example) as I do for values using numpy.where; the pandas.dataFrame.where shows examples using mainly values, but not any string, but is it possible?

obviously the following example does not work, but highlight I guess what I'm trying to perform.

loc_USA = pd.DataFrame.where(df['country'] == 'USA')
loc_USA = pd.DataFrame.where(df[:,1] == 'USA')

Thanks for any suggestion

Paul
