在 Python 中的 (x,y) 图形上创建随机点

Question

I need to create random points (Min 12- Max 18 points between) in (X,Y) graphic.

This points had to be between 0-9 x and y. Like this

import random
import matplotlib.pyplot as plt

x=[1,2,3,4,5,6,7,0,8,9]

y=[1,2,3,4,5,6,0,7,8,9]
print(x+y)

random.shuffle(x)

random.shuffle(y)

a=plt.scatter(x,y, color='k', s=100)

random.shuffle(x)

random.shuffle(y)

b=plt.scatter(x,y, color='k', s=100)

plt.show()

Answer 1

try this:

import random

coords = []
amount_of_coords = 12+random.randint(0, 7)
print(amount_of_coords)

for x in range(amount_of_coords):
    coords.append([random.randint(0, 10),random.randint(0, 10)])

print(coords)

for point in coords:
    plt.scatter(point[0],point[1], color='k', s=100)

plt.show()

output:

12
[[1, 1], [3, 7], [3, 1], [4, 0], [0, 7], [2, 1], [1, 0], [2, 8], [3, 4], [4, 6], [3, 7], [1, 4]]

Answer 2

Is this what you're looking for:

import matplotlib.pyplot as plt
from random import randint

amt = randint(12,19)

x = [randint(1,9) for _ in range(amt)]
y = [randint(1,9) for _ in range(amt)]

plt.scatter(x,y)
plt.show()
