removing characters from list elements in python
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I am extracting content with the help of scrapy into an array. Each element has the unwanted characters ": " inside which I would like to remove as efficient as possible.
v = response.xpath('//div[@id="tab"]/text()').extract()
>>> v
['Marke:', 'Modell:']
>>> for i in v : re.sub(r'[^w]', '', i)
...
'Marke'
'Modell'
Now that seems to work, but how can I retain the result?
In my code, v hasn't changed:
>>> v
['Marke:', 'Modell:']
python regex

I think that pulling in regex for this is a little overkill: use the string replace method:
v = ['Marke:', 'Modell:']
v = [str.replace(':', '') for str in v]
print(v)
Output:
['Marke', 'Modell']
