Several methods of iterative output (index, value) in Python, pythonvalue

The requirements are as follows: index and value of the iterative output sequence ).

1. Create a test list:

>>> Lst = [1, 2, 3, 4, 5]

2. the implementation method is as follows:

# Method 1: range () + len () >>> for I in range (len (lst): print I, lst [I] 0 11 22 33 44 5 # Method 2: enumerate () >>> for index, value in enumerate (lst): print index, value 0 11 22 33 44 5
