#Using train test split
# Although I have already split the data still I will use this function to show that my calculation was correct and to generate that extra y_test variable

x_train,x_test,y_train,y_test=train_test_split[train_df,test_df,test_size=0.33,random_state=17]
split_check=DecisionTreeClassifier(max_leaf_nodes=10,random_state=0)
split_check.fit(x_train,y_train)
y_predict=split_check.predict(x_test)
accuracy_score((y_test,y_predictions)*100)

Output:

File "<ipython-input-55-5d8c72e50bfb>", line 3
    x_train,x_test,y_train,y_test=train_test_split[train_df,test_df,test_size=0.33,random_state=17]

Instead of changing the test size, Just replace the square brackets with parenthesis,That'll solve the error.

Try using this instead of the above code.
Changing the square brackets to parenthesis would solve your problem, if you are query is about the syntactical error.

Python

x_train,x_test,y_train,y_test=train_test_split(train_df,test_df,test_size=0.33,random_state=17)

Thanks and Hope this helped you out.
