If you want to take n lines of input where each line contains m space separated integers like: 1 2 3 4 5 6 7 8 9 a=[] // declaration for i in range(0,n): //where n is the no. of lines you want a.append([int(j) for j in input().split()]) // for taking m space separated integers as input
Here is what the above code is Doing:
1. a=[] // declaration
2. for i in range(0,n): //where n is the no. of lines you want
3. a.append([int(j) for j in input().split()]) // for taking m space separated integers as input
1. a=[] // declaration
2. for i in range(0,n): //where n is the no. of lines you want
3. a.append([int(j) for j in input().split()]) // for taking m space separated integers as input
1. a=[] // declaration
2. for i in range(0,n): //where n is the no. of lines you want
3. a.append([int(j) for j in input().split()]) // for taking m space separated integers as input
1. a=[] // declaration
2. for i in range(0,n): //where n is the no. of lines you want
3. a.append([int(j) for j in input().split()]) // for taking m space separated integers as input
