name 'classification_model' is not defined

Im trying to model in Python 3.5 and am following an example that can be found at here.

I have imported all the required libraries from sklearn.

However I'm getting the following error.

Code:

  from sklearn.linear_model import LogisticRegression
  from sklearn.cross_validation import KFold   #For K-fold cross validation
  from sklearn.ensemble import RandomForestClassifier
  from sklearn.tree import DecisionTreeClassifier, export_graphviz
  from sklearn import metrics

 outcome_var = 'Loan_Status'
 model = LogisticRegression()
 predictor_var = ['Credit_History']
 classification_model(model, loan,predictor_var,outcome_var)

When I run the above code I get the following error: NameError: name 'classification_model' is not defined

I'm not sure how to resolve this as I tried importing sklearn and all the sub libraries.

P.S. I'm new to Python, hence I'm trying to figure out basic steps

Depending on the exact details this may not be what you want but I have never had a problem with

 import sklearn.linear_model as sk

 logreg = sk.LogisticRegressionCV()
 logreg.fit(predictor_var,outcome_var)

This means you have to explicitly separate your training and test set, but having fit to a training set (the process in the final line of my code), you can then use the methods detailed in the documentation [1].

For example figuring out what scores (how many did I get correct) you get on unseen data with the .score method

It appears this code came from this tutorial.

The issue is exactly as the error describes. classification_model is currently undefined. You need to create this function yourself before you can call it. Check out this part of that tutorial so you can see how it's defined. Good luck!
