Question

python中，怎么把这个程序中输出的值的个数计算出来，并输出

Answer 1

我省去中间代码了哈，前面加num = []
后面num.append(i,j,k)
最后，print len(num)

Answer 2

for k in range(1,5):
for j in range(1,5):
for i in range(1,5):
if i!=j and i!=k and j!=k:
print (str(k)+str(j)+str(i),end=' ')

Answer 3

count = 0
for i in range(1, 5):
for j in range(1, 5):
for k in range(1, 5):
if (i != k) and (i != j) and (j != k):
print(i, j, k)
count += 1
print(count)
