Join a list of tuples with a formatting in an efficient manner

Question

I have the following list of tuples

a = [(5, 2), (2, 4)]

And I need to output the following text

(5,2) (2,4)

I have tried

[",".join(str(i) for i in j) for j in a]

And it provides the following list

['5,3', '2,4']

But haven't found an efficient way of getting the desired output, and it must work for a list of tuples of different sizes.

Answer 1

You can use the str.join method with a generator expression like the following:

' '.join('(%s)' % ','.join(map(str, t)) for t in a)

This returns a string with the following content:

(5,2) (2,4)

Answer 2

If all you need to do is get string output then:

1. Convert to a string
2. Strip the brackets

str(a).strip("[]")

out: '(5,2) (2,4)'
