Access list elements inside of tuples


You can do this to get c, for example:

tup_a[1][2]

This works because the second element of tup_a is tup_a[1]. We write [2] at the end of that to access the third element of tup_a[1]. Remember that elements are numbered starting from 0.

You may find it convenient to have a variable pointing to the list:

my_list = tup_a[1]

This expression also works:

(_, my_list) = tup_a

That's called unpacking a tuple. You can also write it without parentheses:

_, my_list = tup_a

Use the underscore, _, if you're not interested in the first element of the tuple. Or put a variable name there if you want to refer to it later.

tup_a = (2014, ['ant', 'bear', 'cat'])
the_value, my_list = tup_a
print('the value is %d' % the_value)
print('my list is %s' % my_list)

Once you have my_list, you can access the elements without worrying about the tuple. Here's a nice way to iterate over the elements of a list:

for i, element in enumerate(my_list):
    print('element %d of my list is %s' % (i,
element))

Scrape elements inside tag properties - Scrapy
My suggestion is you can use split function to obtain your exact result. For example, hxs.select('//embed[@id='flash-player-embed']/@flashvars').extract()[0].split('url_bigthumb=')[1].split('key')[0].replace('&','').strip().replace('&','').strip() This is the simplest way you can use as of now, but you can wait for the good answers. Thanks

Apply changes to selected elements inside the svg element?
I'm writing this as an answer. It's not complete and almost certainly won't be error-free but it should give you the structure to work with. One question: do you really have lots of separate files with one GSS outline in each one? That's unusual, and it's far simpler if they're in one file. I'd start with consolidating your array gssCode: var gssCode = [ {gss:"S12000005",reg:"central"},

Block elements only inside flex item?
Flex items are always rendered as blocks because flex layout only makes sense in a block-like layout. There are a few differences between flex items and block-level boxes which are covered in sections 3 and 4 of the spec, one being that flex items cannot float either, again because this would disrupt the flex layout (and conversely, neither can outside floats intrude into a flex layout). You can
