[Tutor] problem with using set

[Prasad, Ramit]

Approach:-
>>> a='hello'
>>> set(a)
set(['h', 'e', 'l', 'o']), so i am thinking somehow if i remove 'l' and i join the string, i will get the desired output.

2.
>>> a='microsoft'
>>> set(a)
set(['c', 'f', 'i', 'm', 'o', 's', 'r', 't'])
>>> print ''.join(set(a))
cfimosrt

When i print "Hello", i get the output as "helo"(in same sequence) but when i write "microsoft" i get this-"cfimosrt". So, it means i can't predict the outcome of set(a)??
=========================================================================

Are you required to use set? If you are not, I think the following will be easier. 
>>> 'hello'.replace( 'l', '' )
'heo'
>>> 'microsoft'.replace( 'o', '' )
'micrsft'

If you require set, you can do:

>>> s = set("microsoft")
>>> s
set(['c', 'f', 'i', 'm', 'o', 's', 'r', 't'])
>>> s.remove('o')
>>> string = []
>>> for letter in 'microsoft':
...     if letter in s:
...         string.append( letter )
...     
>>> ''.join( string )
'micrsft'
