How to join two tuples into a string?

I have two tuples, one being stored in the variable n, and the other stored in x. I want to join then together into one, final variable that is a string. How can I do this? I tried this but it did not work: 

final = "".join(n) + "".join(str(x))

I am stringing x because it says it can't add STR and INT together

The shortest answer would be 

add n to tuple the convert
final = “”.join(x+(str(n),))
# or simple concatenation 
final = “”.join(x) + str(n)
# or f-string
final = f”{‘’.join(x)}{n}”

If x and n are both tuples and some values in both tuples are not strings, there are three steps:

  1. join tuples
  2. Convert to strings
  3. Join strings
Final = “”.join([str(item)
                 for item in x+n])

When I print it out, there are a bunch commas and parentheses:

(2, 3, 7) ('a', 'a', 'a', 'a', 'a', 'a')

I’ve updated my answer. It might help recommend a specific solution if a sample x and n values are provided.

It also says:

TypeError: sequence item 0: expected str instance, int found

Am I doing something wrong?
