Convert unicode to list of tuples

I have Unicode :-

x = [[u'customer', u'=', 1], [u'parent_id', u'=', False], [u'user_id', u'=', 1059]] <type 'unicode'>

print type(x)
<type 'unicode'>

I need to convert this as a list of tuples like [('customer', '=', 1),('parent_id', '=', False)]

Please help me

Python 2:

>>> x = u"[[u'customer', u'=', 1], [u'parent_id', u'=', False], [u'user_id', u'=', 1059]]"
>>> type(x)
<type 'unicode'>
>>> y=[tuple(t) for t in eval(x)]
>>> y
[(u'customer', u'=', 1), (u'parent_id', u'=', False), (u'user_id', u'=', 1059)]
>>> type(y)
<type 'list'>
>>> type(y[0])
<type 'tuple'>
>>>

>>> map(lambda t: tuple(t),eval(x))
[(u'customer', u'=', 1), (u'parent_id', u'=', False), (u'user_id', u'=', 1059)]
>>>

Python 3:

>>> x = u"[[u'customer', u'=', 1], [u'parent_id', u'=', False], [u'user_id', u'=', 1059]]"
>>> type(x)
<class 'str'>
>>> [tuple(t) for t in eval(x)]
[('customer', '=', 1), ('parent_id', '=', False), ('user_id', '=', 1059)]
>>>

I guess you mean:

>>> x = u"[[u'customer', u'=', 1], [u'parent_id', u'=', False], [u'user_id', u'=', 1059]]"
>>> print type(x)
<type 'unicode'>

You can use eval(x) to translate x to a list.

>>> l = eval(x)
>>> print type(l)
<type 'list'>

Does this work for you?

my_uni_list = [[u'customer', u'=', 1], [u'parent_id', u'=', False], [u'user_id', u'=', 1059]]
result = [tuple(x) for x in my_uni_list]

Just iterate if you are using python 3.x and use tuple()

>>> L = [[u'customer', u'=', 1], [u'parent_id', u'=', False], [u'user_id', u'=', 1059]] <type 'unicode'>
>>> [tuple(i) for i in L]
[('customer', '=', 1), ('parent_id', '=', False), ('user_id', '=', 1059)]
