How can I do this with list comprehension? Or how can I extract every even position element from lis-CodePudding

p = [i.text.strip() for i in soup.select('p.card-text')]
j = []
for i in p:
     if p.index(i)%2 == 0:
          j.append(i)

I am doing this because I only want to extract even position element from my list p.
Is there any other way to do this (to get only even position element from list)?
If not, how can I write the code above using list comprehension? I have extracted even position element using this code. I want to know of any other method I can apply or how to write list comprehension for the above code?

CodePudding user response：

You can try the following by using list comprehension along with enumerate in python

p = [i.text.strip() for index,i in enumerate(soup.select('p.card-text')) if index%2==0]

CodePudding user response：

Um... simply slice:

j = p[::2]

Or if select returns a list (looks like it does), do it earlier to save work:

soup.select('p.card-text')[::2]
