printing strings with format

[leodavinci1990]

Case 1: If I execute the following:

print('{} {}'.format('one', 'two'))

the output in the IDLE shell will be

one two

Case 2: But I execute the following in IDLE:

>>> x = '{} {}'.format('one', 'two')
>>> x

the output will be

'one two'

Why is the output without strings in the first case and with quotes in the second? I understand that there is an implicit print following the primary prompt, i.e. >>>
So why is the output different.

Case 3: Also, in the following:
After defining x, if the

>>>print(x)

The output is:

one two

Is it simply that the implicit Python print after >>> not format outputted strings without quotes?
