我正在編寫一個(gè)文本編碼器/加密器（全部由我自己），但我不明白如何在字符串中附加和替換字符：-/代碼：import os, sys, randomdig = 0text_encoded = ""text = ""try: if os.path.isfile(sys.argv[1]) == True: with open(sys.argv[1], "r") as text: text = text.readlines()except: passif text == "": print("Write the text to encode") text = input()text = text.split()for _ in range(len(text)): text_encoded = text[dig].replace("qwertyuiopasdfghjklzxcvbnm ", "mnbvcxzlkjhgfdsapoiuytrewq@") dig = dig+1print("Your encoded text is:\n"+text_encoded)這是一些輸出：Write the text to encodelo lolo lol lolYour encoded text is:lol如果你能以任何方式幫助我，謝謝:-)

如果我沒(méi)聽錯(cuò)，你想用 m 替換 q，用 n 替換 w 等等。嘗試以下
import os, sys, random
dig = 0
text_encoded = ""
text = ""
try:
if os.path.isfile(sys.argv[1]) == True:
with open(sys.argv[1], "r") as text:
text = text.readlines()
except:
pass
if text == "":
print("Write the text to encode")
text = input()
mychars=list("qwertyuiopasdfghjklzxcvbnm ")
myencode=list("mnbvcxzlkjhgfdsapoiuytrewq@")
charmap=zip(mychars,myencode)
_map = dict(charmap)
encoded_text = ''.join(_map.get(c) for c in text)
print("Your encoded text is:\n"+encoded_text)
您問(wèn)題中的字符串提到您想用@替換''。如果您不想這樣做，只需從上述兩個(gè)字符串中刪除最后一個(gè)字符。

或者你可以使用str.translate
import os, sys, random
from pathlib import Path
TEXT_MAP = ("qwertyuiopasdfghjklzxcvbnm ", "mnbvcxzlkjhgfdsapoiuytrewq@")
def main():
text = ''
if len(sys.argv) > 1:
fname = sys.argv[1]
p = Path(fname)
if p.is_file():
text = p.read_text().strip()
print(f'Text from {p} is: {text}')
if not text:
text = input("Write the text to encode: ").strip()
trantab = str.maketrans(*TEXT_MAP)
text_encoded = text.translate(trantab)
print("Your encoded text is:\n"+text_encoded)
if __name__ == '__main__':
main()

有兩個(gè)列表而不是字符串，例如 from_ = "abc".split() 和 to_ = "def".split() 在 from_ 中查找您的字符并獲取索引，從 to_ 獲取相同的索引字符并將其拼接到一個(gè)新的句子。
example:
from_ = "abc".split()
to_ = "def".split()
old_msg = "ab ab"
new_msg = ""
for each in old_msg.split():
new_msg = new_msg + to_[from_.index(each)]
