#在线编程从哪里进去啊，对于python支持例如numpy这样的包吗 ，还是得自己import啊

#如题，如题，找不到入口诶，请问这个在线编程支持诸如python的统计画图吗，比如这段代码

import sys

import numpy as np

import matplotlib.pyplot as plt

def get_data():

    # example data

    mu = 100 # mean of distribution

    sigma = 15 # standard deviation of distribution

    x = mu + sigma * np.random.randn(10000)

    return x

#you can write your code here

#def draw(IMG_PATH):

#get input data

def draw():

    x = get_data()

    print 'data is : '+str(x)

    # the histogram of the data

    plt.hist(x, bins=50, color='g', alpha=0.5)

    #show image

    plt.show()

    print 'i excute it'

   # plt.savefig(IMG_PATH)

#the code should not be changed

"""if __name__ == '__main__':

    if len(sys.argv)==1:

        print 'error'

    else:

         #the path of image to show

        IMG_PATH = sys.argv[1]+'fig.jpg'

        draw(IMG_PATH)"""

draw()
