The question is simple: How do I repeat a string in Python?
I’m used to PHP.
When I want to repeat a string in PHP, I do so:
var $str = 'StackOverflow';
str_repeat($str, 5);
// Imprime: StackOverflowStackOverflowStackOverflowStackOverflowStackOverflow
I tried that:
'StackOverflow'.repeat(5);
But an error is returned:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'str' object has no attribute 'repeat'

This is enough for you?
str = 'StackOverflow'
print ((str[:13] + ' ') * 5)
Behold working in the ideone. And in the repl it.. Also put on the Github for future reference.
To repetition occurs with the multiplication operator. Many criticize operator overload for use with strings, but if you think about it, it makes sense.
It is possible to take a stretch of string using the operator of Slice, that is, he takes a part of the string which is nothing more, roughly, than a array character.

Just multiply the desired string.
a = 'StackOverflow'
print (a * 5)
the return will be:
'StackOverflowStackOverflowStackOverflowStackOverflowStackOverflow'
In that case, the *=5 will change the value directly in a. So I’d have to just do a * 5 if I wanted the value to repeat without changing the original variable?
'StackOverflow' * 5 directly also serves.
@Wallacemaxters, exact. I’ll edit my answer to make it clearer.
I think posting these variations in the answers can enrich the knowledge :), just a tip

o. O! That’s cool! To do this in PHP I would have to use the
substrandstr_replacechained! Python is very simple– Wallace Maxters
I put it in a way that works in Python 3 as well. What I like about the language is that it tries most of the time to actually make the codes smaller, simpler.
