def AMCount(file_path):
    count_a = 0
    count_m = 0
    with open(file_path, 'r') as file:
        ch = ' '
        while ch:
            ch = file.read(1)
            ch_low = ch.lower()
            if ch_low == 'a':
                count_a += 1
            elif ch_low == 'm':
                count_m += 1

    print("A or a:", count_a)
    print("M or m:", count_m)

AMCount("STORY.TXT")

Output
