Indentation error in python 2.7 shell

Question

Hi when i am copying this complete snippet in python shell it is giving indentation error

import heapq    
dict = {4: 'four', 1 : 'one', 3: 'third', 2: 'two', 5:'five'}
h = []
for value in dict:
    heapq.heappush(h, value)

for i in range(len(h)):
    a = heapq.heappop(h)
    print a,'  ',dict[a]

but if i copy first block

import heapq    
dict = {4: 'four', 1 : 'one', 3: 'third', 2: 'two', 5:'five'}
h = []
for value in dict:
    heapq.heappush(h, value)

hit enter and then copy second block

for i in range(len(h)):
    a = heapq.heappop(h)
    print a,'  ',dict[a]

hit enter and it works fine

please guide where indentation problem is happening.

normally copy and pasting is troublesome in the python shell. consider pasting the code in an editor first and doing any cleanup and then pasting again. — parsethis, Mar 01 '17 at 06:49

I think a tab between two for statement blocks was causing the issue. — commanche, Mar 01 '17 at 07:17

When you paste in the sequence:

for value in dict:
    heapq.heappush(h, value)

for i in range(len(h)):

Auto-indentation results in:

for value in dict:
    heapq.heappush(h, value)

    for i in range(len(h)):

Hence your problem.
