python sm.ols change format of summary to avoid scientific notation

Question

I am running an ols model and I need to know all the coefficients so I can use them in my analysis. How can I display/save the coefficients in a different format than scientific notation?

model = sm.ols(formula="sales ~ product_category + quantity_bought + quantity_ordered + quantity_returned + season", data=final_email).fit()
print model.summary()

Warnings:
[1] Standard Errors assume that the covariance matrix of the errors is correctly specified.
[2] The smallest eigenvalue is 1.19e-29. This might indicate that there are
strong multicollinearity problems or that the design matrix is singular.

This didn't help:

pd.set_option('display.float_format', lambda x: '%3.f' % x)

Answer 1

So that is something that is hardcoded into the statsmodels source. But the best way to get the coefficients out would be with model.params. Take a look at the source for RegressionResults, specifically all of the attributes and that will show you how to access all of the pertinent information for you model fit.
