How can I repeat a string in Perl?

In python

"a" * 4

results in "aaaa"

Can Perl do this too?

Answer 1

It's the repetition (x) operator.

'a' x 4          # 'aaaa'

The x operator can also create lists of repeated elements.

('a','b') x 4    # 'a','b','a','b','a','b','a','b'

Using parens (or qw()) is mandatory if you want to create a list.

Operators are documented in perlop.
