题目描述 python版的，刚开始练习 不是很娴熟~希望多多指正！

python 代码

萌新写法

import sys
gird = []

for line in sys.stdin:
    gird.append((line.split()))

n = int((gird.pop(0))[0])
gird = [[int(gird[j][i]) for i in range(len(gird[0]))] for j in range(len(gird))]

row = len(gird)
col = len(gird[0])
dp = [[0]*col for _ in range(row)]
dp[0][0] = gird[0][0]
for i in range(1,row):
    dp[0][i] = dp[0][i-1] + gird[0][i]
for j in range(1,col):
    dp[j][0] = dp[j-1][0] + gird[j][0]
for i in range(1,row):
    for j in range(1,col):
        dp[i][j] = min(dp[i-1][j],dp[i][j-1]) + gird[i][j]
print(dp[-1][-1])
