1. introduction

adopt Python All kinds of functions and logical relationships can easily solve the problem of large amount of calculation compared with yourself .

2. problem describe

Give any m*n Matrix of size , Find the sum .

3. Algorithm description

First, we need to give the size of the variable specification matrix , Enter the specific value of the matrix through the keyboard and store it in a list , Calculate their sum according to the given matrix specification .

4. Conclusion

In this experiment , We need to use for Loop statement , And it's a cycle plus a cycle . In this experiment , Because there are multiple cycles , Pay attention to the indentation of each line of code , Different indents represent different meanings , The results are different .

Code list 1

m, n = map(int, input().split())
a = []
for i in range(m):
   s = input()
   a.append([int(n) for n in s.split()])
for j in range(m):
   sum = 0
for k in range(n):
       sum += a[j][k]
print(sum)
