WebPython 内置函数 描述 zip () 函数用于将可迭代的对象作为参数,将对象中对应的元素打包成一个个元组,然后返回由这些元组组成的列表。 如果各个迭代器的元素个数不一致,则返回列表长度与最短的对象相同,利用 * 号操作符,可以将元组解压为列表。 zip 方法在 Python 2 和 Python 3 中的不同:在 Python 3.x 中为了减少内存,zip () 返回的是一个对象。 如 … WebFor that, we will assign a color to each # point in the mesh [x_min, m_max]x [y_min, y_max]. if hasattr(clf, "decision_function"): Z = clf.decision_function(np.c_[xx.ravel(), yy.ravel()]) else: Z = clf.predict_proba(np.c_[xx.ravel(), yy.ravel()]) [:, 1] # Put the result into a color plot Z = Z.reshape(xx.shape) ax.contourf(xx, yy, Z, cmap=cm, …
