As others have already posted, your code will create a string that is much
longer than you probably want.  If you are wanting 1024 copies of 'str' in a
new string (yes, 'str' is a bad name to use as it eclipses the builtin
type), then perhaps you want something more like:

longString = 1024 * "This is a string"
