麻烦老师看看这样写是否ok？

def alphabet_translate(str_a):
    str_a=str_a.lower()
    res=''
    for i in str_a:
        if ord(i)>=97 and ord(i)<123:
            x=ord(i)-96
            res=res+(str(x))+' '
    return res
aaa=input()
print(alphabet_translate(aaa))

def alphabet_position(input_string):
    ll = input_string.upper()
    str1 = ''
    for l in ll:
        num = ord(l) - 64
        if 1 <= num <= 26:
            str1 = str1 + str(num) + ' '
    return str1.strip()


msg = "The sunset sets at twelve o' clock."
assert alphabet_position(msg) == "20 8 5 19 21 14 19 5 20 19 5 20 19 1 20 20 23 5 12 22 5 15 3 12 15 3 11"

题解：

import string

def alphabet_position(input_string):
    alphabet_letters = string.ascii_lowercase
    positions = [str(alphabet_letters.find(x) + 1) for x in input_string .lower() if x in alphabet_letters]
    return ' '.join(positions)

msg = "The sunset sets at twelve o' clock."
assert alphabet_position(msg) == "20 8 5 19 21 14 19 5 20 19 5 20 19 1 20 20 23 5 12 22 5 15 3 12 15 3 11"
