Python 3.63、Vigenere cypher打印超出范围

Python 3.63, Vigenere cypher prints more than the range

第一个问题!在提问之前,我试着四处寻找答案,但除了完全不同的代码,我找不到其他任何东西……:\ 我的代码如下:

import sys

if len(sys.argv) != 2:
    print("usage: python vigenere.py key")
    exit(1)

key = (sys.argv[1])
s = input("plaintext: ")
j = 0
for i in range(len(s)):
    # so that j wraps around
    j = j % len(key)
    for j in range(len(key)):
        # check for every j in key if it is upper, or lowercase
        if ord(key[j]) >= ord("A") and ord(key[j]) <= ord("Z"):
            j -= 65
        elif ord(key[j]) >= ord("a") and ord(key[j]) <= ord("z"):
            j -= 97
        # for every capital letter, print out the encyphered letter
        if ord(s[i]) >= ord("A") and ord(s[i]) <= ord("Z"):
            print("1{}".format(chr((ord(s[i]) + j - 65) % 26 + 65), end=''))

        # same for every non capital
        elif ord(s[i]) >= ord("a") and ord(s[i]) <= ord("z"):
            print("2{}".format(chr((ord(s[i]) + j - 97) % 26 + 97), end=''))

        # if it is not capital, print it out
        else:
            print("3{}".format(s[i]), end='')

它是一个vigenere cypher,它需要一个密钥,和一个明文,并用密钥对明文进行加密。当我 运行:

>python vigenere.py abc

plaintext: abc

I get:

2h

2i

2j

2i

2j

2k

2j

2k

2l

(我把 1、2 和 3 放在那里,这样我就可以看到资本和非资本是否有效。)

所以我的问题是,换行符从哪里来?我在每次打印后加上 =end''。 另外,我看不到它如何在范围内打印。我尝试寻找解决方案,但其中包含的代码与我的完全不同。任何人都对我的问题有提示,

移动括号,在您的代码中 end='' 用于 format 函数:

print("1{}".format(chr((ord(s[i]) + j - 65) % 26 + 65), end=''))

print("1{}".format(chr((ord(s[i]) + j - 65) % 26 + 65)), end='')

并在第二个后缩进 for http://rextester.com/VOVSP83705

import sys


key = "key"
s = "abc"

j = 0
for i in range(len(s)):    
    # so that j wraps around
    j = j % len(key)
    for j in range(len(key)):
        # check for every j in key if it is upper, or lowercase
        if ord(key[j]) >= ord("A") and ord(key[j]) <= ord("Z"):
            j -= 65
        elif ord(key[j]) >= ord("a") and ord(key[j]) <= ord("z"):
            j -= 97
    # for every capital letter, print out the encyphered letter
    if ord(s[i]) >= ord("A") and ord(s[i]) <= ord("Z"):
        print("{}".format(chr((ord(s[i]) + j - 65) % 26 + 65)), end='')            

    # same for every non capital
    elif ord(s[i]) >= ord("a") and ord(s[i]) <= ord("z"):
       print("{}".format(chr((ord(s[i]) + j - 97) % 26 + 97)), end='')

    # if it is not capital, print it out
    else:
        print("{}".format(s[i]), end='')
