Question

Assume we have dictionary that translates strings into numbers.

How to reverse it into list ?
Let assume, we can fill not mapped numbers with empty string ''.

Here example how it works:

>>> dic_into_list({'x':0, 'z':2, 'w':3})
['x', '', 'z', 'w']

Answer 1

d = {'x':0, 'z':2, 'w':3}
lst = [""] * (max(d.values()) + 1)
for k, v in d.items():
    lst[v] = k
print(lst)

prints

['x', '', 'z', 'w']
