生成一个由随机数组成的列表
import random
l = [random.randint(1, 20) for i in range(20)]
l1 = [i % 2 for i in l]
print("此数组为：", l)
print(f"此数组中有{l1.count(0)}个偶数,{l1.count(1)}个奇数。")
import random
l = [random.randint(1, 20) for i in range(20)]
l1 = [i % 2 for i in l]
print("此数组为：", l)
print(f"此数组中有{l1.count(0)}个偶数,{l1.count(1)}个奇数。")
