如何在列表列表中生成随机数

Question

I'm here to ask help for a program that I don't know how to resolve:

from random import randint
rain=[]

x=randint(0,500)
y=randint(0,500)

r=2
l=[x,y,r]

for k in range(7):
    rain.append(l)
print(rain)

I just want my program to produce random numbers in the rain list but my code produces:

 [[46, 117, 2],
  [46, 117, 2],
  [46, 117, 2],
  [46, 117, 2],
  [46, 117, 2],
  [46, 117, 2],
  [46, 117, 2]]

Answer 1

You can do it this way:

from random import randint

rain = list()

r = 2

for k in range(7):
    x = randint(0, 500)
    y = randint(0, 500)
    rain.append([x, y, r])
print(rain)
