Getting rid of quotes with strings python

Question

I can't come up with idea how to get rid of quotes that come with every string in my list of tuples. Tried different approaches from internet, still nothing works for me. Could somebody please help me?

This is my exaple:

[('Alabama', 'Montgomery', '32.361538', '-86.279118'),
 ('Alaska', 'Juneau', '58.301935', '-134.41974')]

I need:

[(Alabama, Montgomery, 32.361538, -86.279118),
 (Alaska, Juneau, 58.301935, -134.41974)]

May be what I need is just to read a file in different way:

My raw data, separated with tab:

Alabama Montgomery  32.361538   -86.279118
Alaska  Juneau  58.301935   -134.41974

I read file with this command:

with open('city-data.txt') as f:
    mylist = [tuple(i.strip().split('\t')) for i in f]

You can't if you use repr(..) (or str(..) on lists/tuples), since a repr basically aims to produce an expression, that will generate the object in represents again. You can construct a string where the quotes are removed, but only for printing purposes. — willeM_ Van Onsem

You can create a class and override its __repr__ method to fit your formatting needs, as follows:

inList = [('Alabama', 'Montgomery', '32.361538', '-86.279118'), ('Alaska', 'Juneau', '58.301935', '-134.41974')]

class Formatter:

    def __init__(self, word):
        self.word = word

    def __repr__(self):
        return self.word


outList = [tuple(Formatter(elem) for elem in tup) for tup in inList]
print(outList)

Output:

[(Alabama, Montgomery, 32.361538, -86.279118), (Alaska, Juneau, 58.301935, -134.41974)]

If you mean you want that as a python object, that's impossible – the bareword Alabama doesn't mean anything in python unless it's a symbol bound to a value, which is clearly not what you're going for here. You could convert the numeric strings to numbers, though, and end up with

[('Alabama', 'Montgomery', 32.361538, -86.279118),
 ('Alaska', 'Juneau', 58.301935, -134.41974)]

However, I think you probably just want to print the value without quotes, which is simpler:

out = '['
for tup in your_list:
  out += '({},{},{},{}),\n'.format(*tup)
if your_list:
  out = out[:-2]
out += ']'

print out
# [(Alabama,Montgomery,32.361538,-86.279118),                                                                                                      
# (Alaska,Juneau,58.301935,-134.41974)]
