Question

我正在编写一个将普通文本翻译成摩尔斯电码的程序，而且我编写了将单个字母翻译成摩尔斯电码的核心程序，我仍然无法弄清楚如何翻译整个单词和文本。

更多澄清：我可以翻译单个字母，但我无法翻译整个单词

以下是代码：

from tkinter import *



#key down function
def click():
    entered_text=textentry.get() #this wil collect the text from the text entry box
    outpout.delete(0.0, END)
    try:
        definition = my_dictionary[entered_text]
    except:
        definition= "sorry an error occured"
    outpout.insert(END, definition)    



#### main
window = Tk()
window.title("THIS IS A SIMPLE TITLE")
window.configure(background="yellow")




#create label
Label (window,text="Enter a text here.", bg="YELLOW", fg="BLACK", font="arial 30 bold italic" ) .grid(row=1, column=0, sticky=W)

#create a text entry box
textentry= Entry(window, width=20, bg="WHITE")
textentry.grid(row=2, column=0, sticky=W)

#add a submit button
Button(window, text="SUBMIT", width=6, command=click) .grid(row=3 ,column=0, sticky=W)

#create another label
Label (window,text="THE ENCRYPTED TEXT IS:", bg="YELLOW", fg="BLACK", font="arial 10 bold" ) .grid(row=4, column=0, sticky=W)

#create a text box
outpout = Text(window, width=75, height=6, wrap=WORD, bg="WHITE")
outpout.grid(row=5, column=0, columnspan=2, sticky=W) 

#the dictionary
my_dictionary = {
    "A" : ".-",
    "B" : "-...",
    "C" : "-.-.",
    "D" : "-..",
    "E" : ".",
    "F" : "..-.",
    "G" : "--.",
    "H" : "....",
    "I" : "..",
    "J" : ".---",
    "K" : "-.-",
    "L" : ".-..",
    "M" : "--",
    "N" : "-.",
    "O" : "---",
    "P" : ".--.",
    "Q" : "--.-",
    "R" : ".-.",
    "S" : "...",
    "T" : "-",
    "U" : "..-",
    "V" : "...-",
    "W" : ".--",
    "X" : "-..-",
    "Y" : "-.--",
    "Z" : "--..",
    " " : "/"
    }
#run the main loop
window.mainloop()

Answer 1

你只需要迭代整个句子，使用你的字典来翻译和积累结果，例如列表理解：

sentence = "Hello World"
[my_dictionary[s] for s in sentence.upper()]
# Out: ['....', '.', '.-..', '.-..', '---', '/', '.--', '---', '.-.', '.-..', '-..']

如果您需要一个字符串作为结果，您可以加入列表，其中包含单个翻译和join以及您选择的分隔符，例如＆＃34; |＆＃34;这里：

"|".join([my_dictionary[s] for s in sentence.upper()])
# Out: '....|.|.-..|.-..|---|/|.--|---|.-.|.-..|-..'

我认为问题在于您尝试将整个文本用作字典的关键字。因此，如果文本“A”输入到文本输入中，那么它的作用是“A”是my_dictionary中的键。如果在文本框中输入文本“AS”，则会失败，因为my_dictionary中没有关键字“AS”。

因此，您要做的是循环输入字符串中的每个字符，并将该字母的莫尔斯值添加到您的定义字符串中。您还需要确保该字母为大写（除非保证输入为大写）。这是使用以下示例中的字符串.upper()方法完成的。像下面这样的东西应该做你想要的。

definition = str()  # Create a blank string to add the Morse code to

# Go through each letter and add the Morse definition of the letter to definition
for letter in entered_text:
    definition += my_dict[letter.upper()]  # The upper makes sure the letter is a capital so that there will be a match in my_dict

如何用词典将整个单词翻译成莫尔斯码？
