I have a list
list = ['a:b:c:d', 'e:f:g:h', 'i:j:k:l']
What I'm trying to do is make a list of each of it's elements. Something like this:
listelement[0] = list[0].split(':')
print(listelement[0][1])
output: b
I can't seem to figure out how to create something that works similarly to this.

You can try list comprehension to do what you want.
new_list = [element.split(':') for element in list].
Also I would advise against the use of list as a name, since it's a reserved word.

How can I generate all possible sublists of a given length from a list.
list=[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25]
from this, I want to generate a list of length 5 with all possible unique combinations with no dupes within sublists.
sublists= [1,2,3,4,5], [2,4,5,6,7]....
Thanks

You can do it using itertools.combinations
import itertools
l=[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25]
list(itertools.combinations(l, 5))
Also, don't use built-in such as list to name your variables.

list = [(123,"a"),(125,"b")]
variable = (123,"c")
Is it possible to search for the first element of the variable in the list like this?
if variable[0] in list[0]:
