字符转换器

Question

turk = {"Ç":"C","ç":"c","Ğ":"G","ğ":"g","İ":"I","ı":"i",
        "Ö":"O","ö":"o","Ş":"S","ş":"s","Ü":"U","ü":"u"}

eng = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz \t1234567890"

space = " "

word = input("Enter a word")


def turkChar (word):
    newword = ""
    for c in word:
        if c in eng:
            newword = newword + c
        elif c in turk:
            newword = newword + turk[c]
        else:
            newword = newword + space
    return newword
       

我写了这个简单的代码，将土耳其语字符转换成英语。我添加了一个空格变量来创建一个空格，但若用户想要创建更多的空格、制表符甚至数字，该怎么办呢。我怎么做这个

Answer 1

我想你应该有一张从土耳其语到英语的地图。所以A会映射到A，B到B，等等，除了你已经有的突厥语词典。然后可以将空格、制表符和任何其他字符添加到映射中

您的代码成为一个循环，使用get函数进行字典查找

Answer 2

我认为您不应该将空格、制表符和数字字符与eng字符区别对待。我只想像这样扩展你的角色：

eng = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz \t1234567890"

然后，我们可以删除“空间”部分，结果如下：

turk = {"Ç":"C","ç":"c","Ğ":"G","ğ":"g","İ":"I","ı":"i",
        "Ö":"O","ö":"o","Ş":"S","ş":"s","Ü":"U","ü":"u"}

eng = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz \t1234567890"

word = input("Enter a word")

def turkChar(word, turk):
    newword = ""
    for c in word:
        if c in eng:
            newword = newword + c
        elif c in turk:
            newword = newword + turk[c]
    return newword

• 制表符被写为字符串中的\t
• 注意到eng字符串中缺少一个较低的h
• 您将turk定义为参数，但未将eng定义为参数，或者两者都定义，或者两者都不定义
• 如果在eng或turk中找不到字符，则忽略该字符

Answer 3

Python有一个名为^{}的字符串函数，它是为此而设计的，非常有效（比循环/dict查找效率高很多）。您可以使用与现有词典完全相同的词典创建翻译表，您可以使用^{}创建该表，然后将其传递到translate()：

turk = str.maketrans({"Ç":"C","ç":"c","Ğ":"G","ğ":"g","İ":"I","ı":"i",
        "Ö":"O","ö":"o","Ş":"S","ş":"s","Ü":"U","ü":"u"})

s = "Hellö ĞÇ 123"

s.translate(turk)
# 'Hello GC 123'
