请问这道python咋整😭

import random

x = []
y = []
z = []
for i in range(10):
    a1 = random.randint(10, 100)
    a2 = random.randint(10, 100)
    a3 = random.randint(10, 100)
    x.append(a1)
    y.append(a2)
    z.append(a3)
print("=====原始数据===")
print(x)
print(y)
print(z)
print("=====最大的数===")
num = x + y + z
print(max(num))
print("=====不重複的数===")
b = {}
d=[]
for i in num:
    if num.count(i) == 1:
        b[i] = num.count(i)
for key, value in b.items():
    d.append(key)
print(d)
print("=====不重複的数個數===")
print(len(d))
