How to remove extra space from output list?

[longmen]

Hi,

I have this input

P (0, 2,+1) (2, 0, -1) (0, 4,+1) (4, 0, -1)

and I would like to have it printed out this way

[(0, 2, 1), (2, 0, -1), (0, 4, 1), (4, 0, -1)]

. However, due to the extra space in the input I ran into this error. Without making any change to the input, I wonder if anyone could advise? Thanks

    algorithm_type_2 = list(eval(user_input_2))
  File "<string>", line 1
    (0,,2,+1),(2,,0,,-1),(0,,4,+1),(4,,0,,-1)
       ^
SyntaxError: invalid syntax

user_input = input().split()
# input_list = user_input.split()
# algorithm_type = 'X'
algorithm_type = user_input.pop(0)

user_input_2 = ','.join(user_input)
algorithm_type_2 = list(eval(user_input_2))
print(user_input_2)
print(algorithm_type_2)
