Follow the Jupyter notebook for Ridge$/$Lasso regression. After completing the following statement, enter the value of the TRAINING set accuracy $($to $2$ decimal places$)$ as a number between $0$ and $1($i$.$e$.,$ do NOT enter accuracy as a percentage between $0$ and $100)$::

# Now fit a Ridge regression

from sklearn.linear$\_$model import Ridge

ridge $=$ Ridge$().$fit$($X$\_$train, y$\_$train$)$

print$("$Training set score: $\{$:$\mathrm{.}2$f$\}".$format$($ridge$.$score$($X$\_$train,y$\_$train$)))$

print$("$Test set score: $\{$:$\mathrm{.}2$f$\}".$format$($ridge$.$score$($X$\_$test,y$\_$test$)))$
