# 11.26 (Row sorting) Implement the following function to sort the rows in a twodimensional
# list. A new list is returned and the original list is intact.
# def sortRows(m):
# Write a test program that prompts the user to enter a 3*3 matrix of numbers and
# displays a new row-sorted matrix.
def main():
SIZE = 3
print("Enter a 3 by 3 matrix row by row: ")
m = []
for i in range(SIZE):
line = input().split()
m.append([eval(x) for x in line])
print("The row-sorted list is ")
printMatrix(sortRows(m))
def printMatrix(m):
for i in range(len(m)):
for j in range(len(m[i])):
print(m[i][j], end=" ")
print()
def sortRows(m):
result = []
for row in m:
result.append(row)
for row in result:
row.sort()
return result
