list of strings to list of tuples of string

I have a list of strings of the sort

['aaa','bbb','ccc']

I need to convert them into a list of tuples like this,

[('aaa',),('bbb',),('ccc',)]

When I try to apply the tuple function to each element of the list, it splits the string and returns something of the sort

('a','a','a')

Is there a way to work around this issue?

Don't apply tuple function, since it takes the string as sequence, and breaks it's characters apart. You can simply build tuple manually with List Comprehensionlike this:

>>> l = ['aaa','bbb','ccc']
>>> [(elem,) for elem in l]
[('aaa',), ('bbb',), ('ccc',)]

Using list comprehension, and tuple creation via the 'single item tuple creation method' or look here for information about this.

lst = ['aaa','bbb','ccc']
tpl_lst = [(i,) for i in lst]

Yields:

[('aaa',), ('bbb',), ('ccc',)]

>>> l = ['aaa', 'bbb', 'ccc']
>>> print [(i,) for i in l]
[('aaa',), ('bbb',), ('ccc',)]

All you need to do is put each element in its own one-tuple.
