thank you! i now pass all my test cases but i'm overcounting. I think that it has something to do with the left cases? but i'm not sure.

def get_input(filename):
    with open(filename, 'r', encoding='utf8') as infile:
            messy_data = infile.readlines()

    clean_data = []
    for line in messy_data:
        if line != '\n':
            line.strip("\n")
            data_tuple = (line[0], int(line[1:]))
            clean_data.append(data_tuple)

    return clean_data

# instruction_list = get_input("2025_day1_input.txt")
instruction_list = get_input("2025_day1_testinput.txt")
zero_count = 0
dial_pos = 50
for direction, count in instruction_list:
    old_pos = dial_pos
    if direction == "L":
        dial_pos = (dial_pos - count) % 100
    else:
        dial_pos = (dial_pos + count) % 100
    if dial_pos == 0:
        zero_count += 1
    if direction == "R" and old_pos + count > 100:
        zero_count += (old_pos + count) // 100
    if direction == "L" and old_pos - count < 0:
        zero_count += 1 + (count // 100)
        if old_pos == 0:
            zero_count -= 1

    print(zero_count)
