which classification algorithm is best and why code example

Example 1: best algorithm for classification

for clf in classifiers:    clf.fit(X_train, y_train)    y_pred= clf.predict(X_test)    acc = accuracy_score(y_test, y_pred)    print("Accuracy of %s is %s"%(clf, acc))    cm = confusion_matrix(y_test, y_pred)    print("Confusion Matrix of %s is %s"%(clf, cm)

Example 2: best algorithm for classification

Accuracy of XGBClassifier is 95.55Confusion Matrix of XGBClassifier is [[ 9  0  0]                                      [ 0 15  1]                                      [ 0  1 19]]Accuracy of SVC is 95.55Confusion Matrix of SVC is [[ 9  0  0]                            [ 0 16  0]                            [ 0  2 18]]Accuracy of DecisionTreeClassifier is  88.88Confusion Matrix of DecisionTreeClassifier is [[ 9  0  0]                                               [ 0 15  1]                                               [ 0  4 16]]Accuracy of RandomForestClassifier is  84.44Confusion Matrix of RandomForestClassifier is [[ 9  0  0]                                               [ 0 15  1]                                               [ 0  6 14]]
