python隨機生成 100 行2列的數組，第壹列作為 x 軸，第二列作為 y 軸，繪 制散點圖？

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軸',fontproperties = font)

plt.ylabel('y軸',fontproperties = font)

plt.show()
