len()只能得出单维度参数print(p3)#linspace的使用print(np.linspace(5, 15, 8))#从5开始到15,中间要有8个元素,需要注意的是15是包括在内的print(np.linspace(5, 15, 3, retstep=True))#retstep 是打印出步长,'''结果如下:
Quebec, Canada. It was the first widely used Framework. It is a Python library that helps in multi-dimensional arrays for mathematical operations using Numpy or Scipy. Theano can use GPUs for faster computation, it also can automatically build symbolic graphs for computing gradients...

In a boxplot graph, the box represents the data’s interquartile range (IQR), which is the 50 percent of data points above the first quartile and below the third quartile. Each whisker (line) on the side of a boxplot represents the top and bottom 25 percent of data points, where the...
