How to parse multiple times in python

How to parse multiple times in python:

Method #1:

s = "(0 ,3) :5.0|(1 ,3) : -5.0"

def get_result(s: str) -> tuple:
    goals = []
    rewards = []
    
    for pair in s.split("|"):
        goal, reward = pair.split(":")

        goals.append(eval(goal.strip()))
        rewards.append(float(reward.strip()))

    return (goals, rewards)

print(get_result(s))

Method #2:

txt = "(0 ,3) :5.0|(1 ,3) : -5.0"
txt = txt.replace(" ", "")

goal_states = []
their_rewards = []
for i in txt.split('|'):  # ['(0,3):5.0', '(1,3):-5.0']
    a, b = i.split(':')
    _, n1, _, n2, _ = a    # `a` is something like '(0,3)'

    n1 = int(n1)
    n2 = int(n2)

    goal_states.append((n1, n2))
    their_rewards.append(int(float(b)))

print(goal_states)
print(their_rewards)
 
OUTPUT:

[(0, 3), (1, 3)]
[5, -5]

Method #3:

import ast
s = "(0 ,3) :5.0|(1 ,3) : -5.0"
s = s.replace("|", ",")
ast.literal_eval(f"{{{s}}}")

OUTPUT:
{(0, 3): 5.0, (1, 3): -5.0}
  
 

Method #4:

string = "(0, 3): 5.0|(1 ,3) : -5-0"
parsed_list1, parsed_list2 = [i.split(":") for i in string.split("|")]
print(parsed_list1)
print(parsed_list2)

OUTPUT:
['(0, 3)', ' 5.0']
['(1 ,3) ', ' -5-0']
  
 

Method #5:

goal_states=[]
their_obstacles=[]
for i in "(0 ,3) :5.0|(1 ,3) : -5.0".split("|"):
   goal_states.append(i.split(":")[])
   their_obstacles.append(i.split(":")[1])
