I need to be able to make a list that contains all possible combinations of an inputted list.
For example the list [1,2,3] should return [1 [1,2] [1,3] 2 [2,3] 3 [1,2,3]]
The list doesn’t have to be in any particular order. On this site I’ve found lots of functions using the itertools but those are returning objects when I need just a list.
I imagine there is a simple solution that I am overlooking. Better that than a complicated one, right?
This has always confused me. It seems like this would be nicer:
I’m trying to convert a string to a list of words using python. I want to take something like the following:
I was answering this question, I preferred generator expression here and used this, which I thought would be faster as generator doesn’t need to create the whole list first:
I’m trying to get Python to a read line from a .txt file and write the elements of the first line into a list. The elements in the file were tab- separated so I used split("t") to separate the elements. Because the .txt file has a lot of elements I saved the data found in each line into a separate list.
For example, given the list ['one', 'two', 'one'], the algorithm should return True, whereas given ['one', 'two', 'three'] it should return False.
When should I use a dictionary, list or set?
I have a list:
