# Write a Python program to Convert Matrix to dictionary 
 # Python3 code to demonstrate working of 
# Convert Matrix to dictionary 
# Using dictionary comprehension + range()
  
# initializing list
test_list = [[5, 6, 7], [8, 3, 2], [8, 2, 1]] 
  
# printing original list
print("The original list is : " + str(test_list))
  
# using dictionary comprehension for iteration
res = {idx + 1 : test_list[idx] for idx in range(len(test_list))}
  
# printing result 
print("The constructed dictionary : " + str(res))
