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
