python - 使用字符串替换方法解码莫尔斯电码

Question

    def decodeMorse(morseCode):
x = morseCode.replace(".-", "A")
x2 = x.replace("-...","B")
x = x2.replace("-.-.", "C")
x2 = x.replace("-..", "D")
x = x2.replace(".", "E")
x2 = x.replace("..-.", "F")
x = x2.replace("..-.", "G")
x2 = x.replace("....", "H")
x = x2.replace("..", "I")
x2 = x.replace(".---", "J")
x = x2.replace("-.-", "K")
x2 = x.replace(".-..", "L")
x = x2.replace("--", "M")
x2 = x.replace("-.", "N")
x = x2.replace("---", "O")
x2 = x.replace(".--.", "P")
x = x2.replace("--.-", "Q")
x2 = x.replace(".-.", "R")
x = x2.replace("...", "S")
x2 = x.replace("-", "T")
x = x2.replace("..-", "U")
x2 = x.replace("...-", "V")
x = x2.replace(".--", "W")
x2 = x.replace("-..-", "X")
x = x2.replace("-.--", "Y")
x2 = x.replace("--..", "Z")
x = x2.replace(" ", " ")
print(x)

它替换每个“.”以字母 E 为例，每当我输入“.... . -.--”时，它应该给我“嘿”，但我得到“EEEE E TAT”任何帮助谢谢!

Answer 1

您需要分隔每个字母。与另一个角色。所以 TED 会是“- . -..”，然后使用 split 来分割每个字母或 - 和 . 的字符串。然后替换每个字母。要执行背靠背单词，您需要将其拆分为二维列表。即句子“AC BA CA”-> [['.-','-.-.'],['-...','.-'],['-.-.','.-' ]]那么您将使用此方法，但为外部单元格中的每个项目在字符串中添加一个空格。

def cnvtletter(code):
    if(code==".-"):
        return 'A'
    if(code=="-..."):
        return 'B'
    if(code=="-.-."):
        return 'C'

word= '.-|-.-.|-...'
delimiter='|'
letters=word.split(delimiter)
out=''
for letter in letters:
    out+=cnvtletter(letter)
print out
