'Can Golang multiply strings like Python can?

Python can multiply strings like so:

Python 3.4.3 (default, Mar 26 2015, 22:03:40)
[GCC 4.9.2] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> x = 'my new text is this long'
>>> y = '#' * len(x)
>>> y
'########################'
>>>

Can Golang do the equivalent somehow?

Solution 1:^[1]

Yes, it can, although not with an operator but with a function in the standard library.

It would be very easy with a simple loop, but the standard library provides you a highly optimized version of it: strings.Repeat().

Your example:

x := "my new text is this long"
y := strings.Repeat("#", len(x))
fmt.Println(y)

Try it on the Go Playground.

Notes: len(x) is the "bytes" length (number of bytes) of the string (in UTF-8 encoding, this is how Go stores strings in memory). If you want the number of characters (runes), use utf8.RuneCountInString().

Solution 2:^[2]

Yup. The strings package has a Repeat function.

Solution 3:^[3]

you can use the string package. it has a repeat functionhere
