Hello, guys. First of all I'm very new to Sage, and also this forum, so please be generous to my question..

So, I was wondering given a permutation, say

Permutation([1,2,3,4])

how can I change to a string of the form

'1234'

Thank you for any help.

First, you can get the list of values of P, viewed as strings as follows:

sage: sage: L = [str(i) for i in P]
sage: L
['1', '2', '3', '4']

Then you can join those strings with an empty separator:

sage: ''.join(L)
'1234'

Putting all together (and replacing the list with an iterator (by removing the brackets)) leads to:

sage: ''.join(str(i) for i in P)
'1234'
