Python convert tuple values from unicode to str

Question

What is the best way to convert the values in tuples from unicode to string, when the tuples are in a list, can it be done without looping?

unicodedata.normalize('NKFD', x) can only take unicode, not a tuple. The dataset also includes float values.

EXAMPLE

unicode_tuple_list = [(u'text in unicode', u'more unicode'), (u'more text in unicode', u'even more unicode')]
print type(unicode_tuple_list) # list - keep as list
print type(unicode_tuple_list[0]) # tuple - keep as tuple 
print type(unicode_tuple_list[0][0]) # unicode

How can all these values be made a str?

Answer 1

I'm not sure there is a way to convert this without using a loop/list comprehension.

I would use the map function to accomplish this, see:

unicode_tuple_list = [(u'text in unicode', u'more unicode'), (u'more text in unicode', u'even more unicode')]
string_tuple_list = [tuple(map(str,eachTuple)) for eachTuple in unicode_tuple_list]
print string_tuple_list

• cycle_about: Thank you Michael, this works great except for a part of the dataset with non-ascii characters. Is there a way to use map to also force encode the tuple values to ascii?
• Michael Goodwin: If you don't need to preserve the special characters you could look at this: stackoverflow.com/a/35536228/7108103 if you do need to keep them you can look at this: stackoverflow.com/questions/19527279/…

Answer 2

Unpack the tuples, convert to a string and repack.

Answer 3

tuple(map(str, unicode_tuple_list))
