Make dictionary from list with python [duplicate]

Question

dict(x[i:i+2] for i in range(0, len(x), 2))

Here are a couple of ways for Python3 using dict comprehensions

>>> x = (1,'a',2,'b',3,'c')
>>> {k:v for k,v in zip(*[iter(x)]*2)}
{1: 'a', 2: 'b', 3: 'c'}
>>> {x[i]:x[i+1] for i in range(0,len(x),2)}
{1: 'a', 2: 'b', 3: 'c'}

dict(zip(*[iter(val_)] * 2))

>>> x=(1,'a',2,'b',3,'c')
>>> dict(zip(x[::2],x[1::2]))
{1: 'a', 2: 'b', 3: 'c'}

x = (1,'a',2,'b',3,'c') 
d = dict(x[n:n+2] for n in xrange(0, len(x), 2))
print d
