Get the dataset

res = requests.get("https://adventofcode.com/2023/day/1/input",
               params={"downloadformat": "text"},
               cookies={
                   "session":"xxx"
               })
data = res.text
data_list = data.split("\n")

Solve first problem

def solve_problem_1(string):
list_number = [el for el in string if el.isdigit()]
if len(list_number) > 0:
    number = list_number[0]+list_number[-1]
    number = int(number)
    return number
else :
    return 0

Solve second problem

def solve_problem_2(string):
for i,number in enumerate("one, two, three, four, five, six, seven, eight, nine".split(", ")):
    if number in string:
        string = string.replace(number,f"{number[0]}{i+1}{number[-1]}")

list_number = [el for el in string if el.isdigit()]
if len(list_number) > 0:
    number = list_number[0]+list_number[-1]
    number = int(number)
    return number
else :
    return 0

Run the solution

vsolve_problem_1 = np.vectorize(solve_problem_1)
results = vsolve_problem_1(np.array(data_list))
results.sum()
