Changing values in list: Python

Question

I\'m making a function to modify the elements in a list, but it doesn\'t change all the way through... My function is:

def modifyValues(l):
    for x in l:
          


        

Answer 1

You should dictionary instead to change item in the list.

>>> def modifyValues(l):
...     d = {'a': 1, 'b': 2, 'c': 3}
...     modifyl = [k for i in l for k in d  if d[k] == i]
...     print(modifyl)
... 
>>> modifyValues([1, 2, 3, 2, 3, 1, 2, 2])
['a', 'b', 'c', 'b', 'c', 'a', 'b', 'b']
>>>

You can also use the ascii_lowercase constant from string

>>> from string import ascii_lowercase
>>> def modifyValues(l):
...     modifyl = [v for i in l for k, v in enumerate(ascii_lowercase, 1)  if i == k]
...     print(modifyl)
... 
>>> modifyValues([1, 2, 3, 2, 3, 1, 2, 2])
['a', 'b', 'c', 'b', 'c', 'a', 'b', 'b']
