Apr 30, 2013 · Since Python 3.5 (PEP 448 -- Additional Unpacking Generalizations) one can use the following literal syntax to convert a tuple to a list: >>> t = (1,2,3) >>> lst = [*t] >>> lst [1, 2, 3] >>> *lst, # back to tuple (1, 2, 3) A list comprehension can be use to convert a tuple of tuples to a list of lists: >>> level1 = ( ... (1,1,1,1,1,1), ...

Suppose I have a list of tuples and I want to convert to multiple lists. For example, the list of tuples is [(1,2),(3,4),(5,6),] Is there any built-in function in Python that convert it to: [1,3,5],[2,4,6] This can be a simple program. But I am just curious about the existence of such built-in function in Python.

How do I convert [(1,), (2,), (3,)] to [1, 2, 3]

Jun 26, 2014 · How do I convert a tuple inside a list into a list. For example, [(23,5,6,4)]=>[23,5,6,4] This is a very ...

L is a list and we want to convert it to a tuple. L = [1, 2, 3] tuple(L) By invoking tuple, you convert the list (L) into a tuple. As done above. >> (1, 2, 3) you can go ahead and access any item in the tuple using the square brackets. L[0] 1

I am newbie to Python and need to convert a list to dictionary. I know that we can convert a list of tuples to a dictionary. This is the input list: L = [1,term1, 3, term2, x, term3,... z, termN] and I want to convert this list to a list of tuples (or directly to a dictionary) like this: [(1, term1), (3, term2), (x, term3), ...(z, termN)]

Feb 12, 2013 · List comprehensions read more like everyday code - readability is subjective (those used to functional languages will be used to map()), but I'd say the only readable case for map is the simple case where you are using an existing function or type - defining a new function (including lambdas) for a map() is never going to be more readable than a list comprehension.

Jul 8, 2010 · But I feel like there must be a way to do this with a list comprehension. A simple [list(tuple) for tuple in tupleOfTuples] just gives you a list of lists, instead of individual elements. I thought I could perhaps build on this by using the unpacking operator to then unpack the list, like so: [*list(tuple) for tuple in tupleOfTuples] or

Jul 21, 2010 · The spacing here isn't actually as you stipulated; if that's important, this approach won't work as python adds a space after each item in a list/tuple. – Benj Commented Jul 20, 2010 at 17:47

Update for Python 3: In Python 3 map returns an iterator and not a list. This is the fastest from a few options I've tested (timed using the timeit module): [list(t) for t in zip(*lists)]
