Nested loop patterns practice questions Python

There are 7 steps/challenges to this assignment. Complete all steps for full credit.

Submit your code together with program output to the text submission window.

1. Start a new program with the code that follows. Notice how the for loop that uses variable x as a counter encloses a second for loop that uses variable y as a counter. One way to visualize this code is to consider the x loop counting rows while the y loop is counting columns in a grid.

print("x, y")
for x in range(1, 4):  # outer loop
  for y in range(1, 5):  # inner loop
    print(x, ",", y, end="    ")
  print()
print()

# Output
x, y
1 , 1    1 , 2    1 , 3    1 , 4    
2 , 1    2 , 2    2 , 3    2 , 4    
3 , 1    3 , 2    3 , 3    3 , 4        
2. Modify the code above (part 1). Add an additional nested loop structure (see below) to create the output that follows: 

print("x, y")
for x in range(1, 4):  # outer loop
  for y in range(1, 5):  # inner loop
    print(x, ",", y, end="    ")
  print()
print() 

# add additional code here

# Output
x, y
1 , 1    1 , 2    1 , 3    1 , 4    
2 , 1    2 , 2    2 , 3    2 , 4    
3 , 1    3 , 2    3 , 3    3 , 4    

x: 1  y: 1 2 3 4 
x: 2  y: 1 2 3 4 
x: 3  y: 1 2 3 4
