Say I have a list of names like so:

names = ['Ted Cruz', 'Donald Trump', 'Cruz']

I want to replace the third element, 'Cruz', with its corresponding full name found in the first element. How can I achieve this in a general sense, If I have a very long list of names and can't manually check?

CodePudding user response：

I assume, full names have space between first name and last name, so I do this:

list_of_partial_names = list()
partial_name_to_full_name = dict()
names = ['Ted Cruz', 'Donald Trump', 'Cruz']
for name in names:
   parts_of_name = name.split()
   if len(parts_of_name) == 1:  # it's not a full name
       list_of_partial_names.append(parts_of_name[0])
   else:
       for part in parts_of_name:
           partial_name_to_full_name[part] = name

# To replace all partial names with full name
for index,name in enumerate(names):
    if name in partial_name_to_full_name:
        names[index] = partial_name_to_full_name[name]

print(names)

Output:

['Ted Cruz', 'Donald Trump', 'Ted Cruz']
