Replace element of a list in python

Question

I have list and i want to replace all the elements os the list with another elements.
Code:

list1 = ['1','1','3','4','5','2','3','4']                                           
dict1 = {'dict1' : ['1','2','3','4','5'] ,'name':['su5','pra4','sa3','ma2','sri1']}            
for x in range(len(dict1['dict1'])):    
      list1 = [word.replace(dict1['dict1'][x],dict1['name'][x]) for word in list1]   
print(list1)

Actual Output:

['susri1', 'susri1', 'sa3', 'ma2', 'sri1', 'prama2', 'sa3', 'ma2']

Expected Output:

['su5','su5','sa3','ma2','sri1','pra4','sa3','ma2']

What if an element is '12'? Do you want to rename it to su5pra4? — willeM_ Van Onsem

That's a very strange dictionary if you transform the dictionary so you can use it as a direct mapping then this is a relatively easy thing to do, e.g.:

>>> dict2 = dict(zip(dict1['dict1'], dict1['name']))
>>> [dict2[i] for i in list1]
['su5', 'su5', 'sa3', 'ma2', 'sri1', 'pra4', 'sa3', 'ma2']
