我正在用 Python 编写一个非常粗糙的 Caesar Cipher,它可以很好地处理简单的消息,但是当我输入完整的字母表时,我在第 16 行出现错误,说存在索引错误:字符串索引超出范围。谁能帮我找出问题所在?这是我的代码:
abc = "ABCDEFGHIJKLMNOPQRTUVWXYZ"
m = str(input("Message: "))
m = m + "~"
m_t = m.index("~")
o = int(input("Offset: "))
e_m = "Encrypted Message: "
for loop_counter in range(m_t):
c = m[loop_counter]
if c in abc:
p = abc.index(c)
p = p + o
if 25 < p:
p = p - 26
elif 0 > p:
p = p + 26
n_c = abc[p]
e_m = e_m + n_c
else:
e_m = e_m + c
print(e_m)
