新Python项目：替换式密码
2022 Update：警示后人：不查自带函数的后果很严重！ 额...发现可以把文字转码后+1/-1来实现
最近我才学定义函数，写了一个替换式密码小程序。
1.替换式密码.py
这个程序是可以被调用的，一共有两个函数，分别是jiami"(加密）jiemi（解密）。jiami调用时传入两个参数，第一个是明文，第二个是移位值，传回密文。jiemi调用时也传入两个参数，第一个是密文，第二个是移位值，传回明文。
# 文件名：替换式密码.py
# 包括两个函数
def jiami(ming, yi):
mi = ""
ming_old_list = list(ming)
ming = ""
for y in range(0, yi):
for i in ming_old_list:
if i == "a":
mi += "b"
elif i == "A":
mi += "B"
