如何使用python将文本中的url提取出来?
使用python，比如有个字符串：
myString = "This is my tweet check it out http://tinyurl.com/blah"
请问，如何才能将 http://tinyurl.com/blah 提取出来?

一般都是使用正则表达式来处理，这里提供两段代码供参考:
import re
myString = "This is my tweet check it out http://tinyurl.com/blah"
print re.search("(?P<url>https?://[^\s]+)", myString).group("url")
或者，查找所有的url
import re
myString = "This is my tweet check it out http://tinyurl.com/blah"
print re.findall('http[s]?://(?:[a-zA-Z]|[0-9]|[$-_@.&+]|[!*\(\),]|(?:%[0-9a-fA-F][0-9a-fA-F]))+', myString)
