S = "I love Beijing tian'an? "
C = S. _ ITER _ () # Get iterator
# Print (c) # print the iterator address
# Print (C. _ next _ () # print the next one in the iterator
# Print (C. _ next __())
# Print (C. _ next __())
# Print (C. _ next __())
# Print (C. _ next __())
# Print (C. _ next __())
# Print (C. _ next __())

# So the iterator operates print (C. _ next _ () at the most! Big! Good! ! You can output data one by one without writing.


For I in S:
Print (I) # The for traversal is all out at once, which will occupy the memory
