如何在python中进行for循环输出？

Question

输出本身正在工作，但我如何使用for循环外部格式化输出或将其写入变量或数组？

...
for item in soup.findAll('span', {"itemprop":"actor"}):
    print item.text
...

输出示例：

Sylvester Stallone
Arnold Schwarzenegger

但输出应该类似于：

Actors: Sylvester Stallone, Arnold Schwarzenegger

Answer 1

actor_list = soup.findAll('span', {"itemprop":"actor"})
print "Actors: {0}".format(", ".join(actor_list))

Answer 2

你可以做的一件事是......

actors = [item.text for item in soup.findAll('span', {"itemprop":"actor"})]
print "Actors: %s" % (", ".join(actors))

Answer 3

不将其保存到变量：

print "Actors: ",
...
for item in soup.findAll('span', {"itemprop":"actor"}):
    print item.text, ",",
...
