def printIt(ar):
for row in range(len(ar)):
for col in range(len(ar[0])):
print(ar[row][col], end=" ")
print("")
N=[]
for r in range(4):
N.append([])
for r in range(len(N)):
value=1
for c in range(5):
N[r].append(value)
value=value + 1
printIt(N)
print("")
newValue=1
for r in range (len(N)):
for c in range(len(N[0])):
N[r][c] = newValue
newValue = newValue + 1
printIt(N)
