Converting '1a2b3c' string to Dictionary

[buran]

from more_itertools import chunked, sliced

spam = '1a2b3c4d'

# without using more_itertools 
print(dict(zip(spam[::2], spam[1::2])))

# using more_itertools
print(dict(chunked(spam, 2)))
print(dict(sliced(spam, 2, strict=True)))

Output:
{'1': 'a', '2': 'b', '3': 'c', '4': 'd'}
{'1': 'a', '2': 'b', '3': 'c', '4': 'd'}
{'1': 'a', '2': 'b', '3': 'c', '4': 'd'}
