python随机生成 100 行2列的数组，第一列作为 x 轴，第二列作为 y 轴，绘 制散点图？

import matplotlib.pyplot as plt
from matplotlib.font_manager import FontProperties
import random
import numpy as np
import array

xlist=[]
ylist=[]
xylist = []
a = [[np.random.randint(1, 100) for j in range(1, 3)] for i in range(1, 101)]
print(a)
for x,y in a:
xlist.append(x)
ylist.append(y)

plt.scatter(xlist,ylist)

font = FontProperties(fname=r"c:\windows\fonts\simsun.ttc", size=15)
plt.xlabel('x轴',fontproperties = font)
plt.ylabel('y轴',fontproperties = font)
plt.show()
