draw roc curve using python sklearn, Matplotlib

import matplotlib.pyplot as plt
from sklearn.metrics import roc_auc_score, average_precision_score
from sklearn import metrics


gt = [1, 0, 1, 0, 1, 1] #origin
pre = [0.9, 0.5, 0.8, 0.4, 0.5, 0.8] #predict
fpr, tpr, thresholds = metrics.roc_curve(gt, pre)

remove duplicated tuple item in list (python code)

 

print(tuple_list)
tuple_list = [ tuple(sorted(tuple_list[i])) for i in range(len(tuple_list))]
tuple_list = list(set(tuple_list))
print(tuple_list)


before:

[(0, 0), (0, 1), (0, 3), (1, 0), (1, 1), (1, 2), (2, 1), (2, 2), (2, 3), (3, 0), (3, 2), (3, 3)]

After:
[(0, 1), (1, 2), (0, 0), (3, 3), (2, 3), (2, 2), (0, 3), (1, 1)]
