NameError: name 'xrange' is not defined

Testing this on python3 and jupyter notebook, I get:

---

NameError Traceback (most recent call last)

in () 1 #Step 4 - Plot the predictions! ----> 2 predictions = lstm.predict_sequences_multiple(model, X_test, 50, 50) 3 lstm.plot_results_multiple(predictions, y_test, 50) ~\git\How-to-Predict-Stock-Prices-Easily-Demo\lstm.py in predict_sequences_multiple(model, data, window_size, prediction_len) 99 #Predict sequence of 50 steps before shifting prediction run forward by 50 steps 100 prediction_seqs = [] --> 101 for i in xrange(len(data)/prediction_len): 102 curr_frame = data[i*prediction_len] 103 predicted = [] NameError: name 'xrange' is not defined

Replacing xrange with range for python3 I get this:

---

TypeError Traceback (most recent call last)

OK fixed it with int() function and range for usage in python3.

sorry, i don't understand,is for i in range(int(len(data)/prediction_len)）？？
