Change type of group of objects

I need to convert a group of variables (result sets from BeautifulSoup) into strings. Is there an elegant way to do this to all of them at once instead of one by one? I was thinking something like this - 

for name in [company_name, company_address, company_logo, company_cat, company_lat, company_phone, company_fax]:
    name = str(name)

I would also like to do a similar thing with re.sub - 

for name in [company_name, company_address, company_logo, company_cat, company_lat, company_phone, company_fax]:
    re.sub('<[^<]+?>', '', name)

Thanks

for name in [company_name, company_address, company_logo, company_cat, company_lat, company_phone, company_fax]:
    name = str(name)

This will not work because you are modifying the list inside the for loop, you can however use a list comprehension for this, which is a one-liner:

list_as_strings = [str(name) for name in [company_name, company_address, company_logo, company_cat, company_lat, company_phone, company_fax]]

Demo

>>> a = [1, 2, 3, 4]

>>> for i in a:
...     i = str(i)
...
>>> a
[1, 2, 3, 4]


>>> b = [str(i) for i in a]
>>> b
['1', '2', '3', '4']

List comprehension should be faster but this solution can be more readable for you.

list1 = [company_name, company_address, company_logo]

list2 = []

for name in list1:
    list2.append( str(name) )

company_name, company_address, company_logo = list2

Now you have strings in previous variables.
