python矩阵中的最小元素
只会最开始的输入，然后遍历矩阵不知道怎么写，之后又该怎么定位呢？
nums=[]
for i in range(5):
nums += list(map(int,input().split()))
minnum=min(nums)
x=nums.index(minnum)
row = x//5
col = x-5*row
print(row,col,minnum)
nums=[]
for i in range(5):
nums += list(map(int,input().split()))
minnum=min(nums)
x=nums.index(minnum)
row = x//5
col = x-5*row
print(row,col,minnum)
