Cryptography Learning (i) Python implements two simple cryptographic algorithms

string Reverse Output

As the name suggests = =|

#!python3.3

def stringreverse (s): "" "
    @param s:string
    @return: Reversed string
    @example:
    Stringreverse (' abc ')
    output CBA "" "Return
    s[::-1]  #start: end:step

Caesar's password replaces the letter with the following key letter, such as key=3 a-> d b-> e c-> f ...

#!python3.3

def caesarcipher (S, key): "" "
    @param s:text needs encrypt/decrypt
    @param key: Positive if encryption, negative if decryption
    @return: The encrypted or decrypted text   
    ""
    import string< C19/>a = string.ascii_lowercase
    b = string.ascii_uppercase
    key = key%      #key must be within 0-25
    t A = A[key:] + a[:key]
    TB = B[key:] + b[:key]
    table = S.maketrans (a+b, TA+TB) return
    s.translate (table)

As long as it's a replacement password (simply by replacing one letter with another), this site will certainly give you a wonderful answer:)
