How to create a list of tuples in python?

Question

I have a function which accepts a list of tuples. I only have an array of integers and want to convert it into list.

I have this:

[1,2,3]

What I want:

[(1),(2),(3),(4)]

Answer 1

You can create a list of tuples using a list comprehension:

>>> tuples = [(x,) for x in [1, 2, 3]]
>>> print(tuples)
[(1,), (2,), (3,)]

The comma in (x,) is the tuple operator which makes the comprehension create tuples rather than just ints.
