输出从5种颜色中随机选2种的所有组合。
是组合不是排列

from itertools import combinations
colors=['red','green','yello','blue','black']
lists=[]
for c in combinations(colors, 2):
    lists.append(c)
print(lists)

colors = ("红","橙","绿","蓝","紫")
for i in range(len(colors)-1):
    for j in range(i+1, len(colors)):
         print([colors[i], colors[j]])
