Different lines of input and output in Python

I’m currently trying to solve the max value problem. However, I’m now having a hard time getting many outputs at the same time. I try to use input().splitlines() to do it, but I only get one output. The test case and output need to have many lines just as the box’s examples. If anyone can provide me with some assistance, I would be very much appreciated it.

Example:
Input:
1,2,3
4,5,6
7,8,9

output:
3 
6
9

for line in input().splitlines():

   nums = []
   for num in line.split(','):
       nums.append(int(num))
       print(nums)
   max(nums) 

Answer

input does not handle multiline, you need to loop. You can use iter with a sentinel to repeat the input and break the loop (here empty line).

nums = []
for line in iter(input, ''):
    nums.append(max(map(int, line.split(','))))
print(nums)

example:

1,2,3
4,5,6
7,8,9

[3, 6, 9]

NB. this code does not have any check and works only if you input integers separated by commas
