Python convert tuple to string

I have a tuple of characters like such:

('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e')

How do I convert it to a string so that it is like:

'abcdgxre'

Try this also reduce(add, ('a', 'b', 'c', 'd')) – Moonier

what is add in this exmple @GrijeshChauhan? – Skilful

@Skilful You need to import add function from operator module. Btw "".join better suits here but if you want to add different types of objects you can use add Check this working example – Moonier

@intel3, How can we remove the tuple outside of the dictionary??({'entities': [[44, 58, 'VESSEL'], [123, 139, 'VESSEL'], [146, 163, 'COMP'], [285, 292, 'ADDR'], [438, 449, 'ADDR'], [452, 459, 'ADDR']]},) – Wax

@Wax Those aren't tuples. – Beehive

Answer 1

Use str.join:

>>> tup = ('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e')
>>> ''.join(tup)
'abcdgxre'
>>>
>>> help(str.join)
Help on method_descriptor:

join(...)
    S.join(iterable) -> str

    Return a string which is the concatenation of the strings in the
    iterable.  The separator between elements is S.

Doesn't work if tuple contains numbers. Try tup = (3, None, None, None, None, 1406836313736) – Tritium

For numbers you can try this: ''.join(map(str, tup)) – Hierocracy

For Numbers and None please try ''.join(map(lambda x: str(x or ''), (None, 1, 2, 'apple'))) – Tamar

Answer 2

here is an easy way to use join.

''.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

Answer 3

This works:

''.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

It will produce:

'abcdgxre'

You can also use a delimiter like a comma to produce:

'a,b,c,d,g,x,r,e'

By using:

','.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

Of course it works. It was marked as the accepted answer 5 years before you posted. – Disclamation

Answer 4

If just using str() for a tuple as shown below:

t = ('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e')

print(t, type(t))

s = str(t) # Here

print(s, type(s))

Only the type can be changed from tuple to str without changing the value as shown below:

('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e') <class 'tuple'>
('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e') <class 'str'>
