Python中的chr()函数与ord()函数解析

s = input()
t = ""
for c in s:
    if 'a' <= c <= 'z':
        t += chr( ord('a') + ((ord(c)-ord('a')) + 3 )%26 )
    elif 'A' <= c <= 'Z':
        t += chr( ord('A') + ((ord(c)-ord('A')) + 3 )%26 )
    else:
        t += c
print(t)

>>> ord("A")
65
>>> ord("a")
97
>>> ord("8")
56

chr(97)
'a'
>>> chr(65)
'A'

def FORMatStrToInt(target):
    for i in range(len(target)):
        temp=ord(target[i])
        print (temp)
    return
 if __name__=="__main__":
     FormatStrToInt("abcdefghijk")
