Like Windows command prompt is not.  I tried:

C:\Users\Terry>python -c "for i in range(5):\n\tprint('hello world')"
   File "<string>", line 1
     for i in range(5):\n  print('hello world')
                                              ^
SyntaxError: unexpected character after line continuation character

-c does not preprocess the code string before executing.  I may propose 
that it do so.  However, Python is still pretty awesome.

C:\Users\Terry>python -c "exec('''for i in range(5):\n  print('hello 
world')''')"
hello world
hello world
hello world
hello world
hello world

One can even combine -i (interactive) with -c (code).

C:\Users\Terry> python -i -c "exec('''a=[]\nfor i in 
(1,2,3):\n\ta.append(i)''')"
 >>> a
[1, 2, 3]
 >>>
