Once you will trained your model, you would know the order of the coefficients:
model_1 = linear_model.LinearRegression()
model_1.fit(train_data[model_1_features], train_data['price'])
print(list(zip(model_1.coef_, model_1_features)))
You will get to know the coefficients and the correct feature.
If you want to reuse the coefficients later you can also put them in a dictionary:
coef_dict = {}
for coef, feat in zip(model_1.coef_,model_1_features):
coef_dict[feat] = coef
Hope this answer helps you! Thus, for more details study the Linear Regression Python.
