Как я могу проверить несколько строк быстро?

Question

Предположим, я брошу hithub, и я вижу некоторый код в python, который я хотел бы запустить на своем ноутбуке. Есть ли способ просто скопировать, вставить его и запустить без создания файла, вставить код и запустить его?

Я попытался запустить ipython на терминале, затем %cpaste и, наконец, вставил код, но он не сработал.

Спасибо!

UPDATE: (больше информации)

Я попытался запустить это:

import scrapy 

class RedditScraper(scrapy.Spider): 
    keyword  = raw_input("Enter the keyword to scrap: ") 
    name  = 'redditscraper' 
    oop_url  = 'https://www.reddit.com/r/'+keyword 
    start_urls = [oop_url] 

    def parse(self, response): 
      for post in response.css('a.title.may-blank::text').extract(): 
       print post + "\n" 

, и я получил это:

Answer 1

%paste работает для меня.

В редакторе я отступ с вкладкой

def foo(x): 
--->return x 

сделать Копируй

In [892]: %paste 
def foo(x): 
     return x 

## -- End pasted text -- 

In [893]: foo(2) 
Out[893]: 2 

Собственно ctrl v пасту, и без %cpaste работ, а также. Что заставляет меня задаться вопросом, происходит ли что-то еще. Ваша вставка из github не сохраняет никаких забавных символов.

ОК, это не вкладка отступа, которая вызывает проблему, является внутренней. Если добавить еще 2 вкладки функции

def foo(x): 
    x = 34
