寻找PHP的str_split()替换

Question

假设我有一小段代码:

<?php 
$tmp = str_split('hello world!',2);
// $tmp will now be: array('he','ll','o ','wo','rl','d!');
foreach($tmp AS &$a) {
  // some processing
}
unset($tmp);
?>

我怎么能在Python v2.7中做到这一点？

我以为这样做会:

the_string = 'hello world!'
tmp = the_string.split('',2)
for a in tmp:
  # some processing
del tmp

但它返回一个"空分隔符"错误.

有什么想法吗？

Answer 1

for i in range(0, len(the_string), 2):
    print(the_string[i:i+2])
