Convert a list to a list of 2 tuples

I have a list:

list = [1, 2, 3]

I want to get this list and add a tuple so that this list becomes like this

T_list = [(1,x), (2, x), (3,x)]

How should I do it?

Use a simple list comprehension for this:

>>> your_list = [1, 2, 3]
>>> x = 100
>>> your_list_with_tuples = [(k, x) for k in your_list]
>>> your_list_with_tuples

Output



[(1, 100), (2, 100), (3, 100)]

Also, don't name variables list

, dict

etc., because they hide built-in types / functions.

Understanding the list will do the trick:

t_list = [(y,x) for y in original_list]


Besides, the commentator is right. Don't include your lists list

. This is a built-in function. Using this for something else can cause problems on the line.

Here's my attempt, although I'm not an expert.

lis = [1,2,3]
tup = (4, 5, 6)

new_tup = tuple(lis)
new_lis = []
for i in range(0,3):
    data = (new_tup[i],tup[i])
    new_lis.append(data)
print(new_lis)
