我想删除URL /电子邮件地址中的所有空格。地址在“普通”字符串中,例如:"Today the weather is fine. Tomorrow, we'll see. More information: www.weather .com or info @weather.com"
我正在寻找一个好的正则表达式(使用Python的re
模块),但是我的版本无法处理所有情况
re.sub(u'(www)([ .])([a-zA-Z\-]+)([ .])([a-z]+)', '\\1.\\3.\\5')
答案 0 :(得分:0)
您的url表达式只需要稍作修改即可。电子邮件的regex表达式也可以从url表达式继承。
>>> #EXPRESSIONS:
>>> url = "(www)+([ .])+([a-zA-Z\-]+)+([ .])+([a-z]+)"
>>> ema = "([a-zA-Z]+)+([ +@]+)+([a-zA-Z\-]+.com)"
>>>
>>> #IMPORTINGS:
>>> import re
>>>
>>> #YOUR DATA:
>>> string = "Today the weather is fine. Tomorrow, we'll see. More information: www.weather .com or info @weather.com"
>>>
>>> #Scraping Data
>>> "".join(re.findall(url,string)[0])
'www.weather.com'
>>> "".join(re.findall(ema,string)[0]).replace(" ","")
'info@weather.com'
>>>
