如何在詞典菜單中選擇單詞？

Question

我正在使用python 2編寫英語詞典。我創建了詞典。 例如，字典鍵中的“家”和“馬”。 如果用戶鍵入“ ho”，則會出現“ home”和“ horse”。 我把這些放在最底線。 但是，當用戶選擇單詞1時，我想在我首先設置的字典中調用鍵和值。 我該怎么做？

myEngDict = {"horse": "The horse (Equus ferus caballus) is one of two extant subspecies of Equus ferus","home": "the place where one lives permanently, especially as a member of a family or household."}

def Words():
    word_List = []
    count = 0
    search_words = raw_input("Please enter a search term: ")
    for i in myEngDict.keys():
        if i.startswith(search_words):
            count+=1
            word_List.append(i)
            print "{}{}{}".format(count,".", i)
        else:
            pass
    choose = input("Which one?")

例如，如果“家”首先出現，則用戶選擇1：

程序顯示：

home: the place where one lives permanently, especially as a member of a family or household.

Answer 1

首先，您應該在最后一行中使用raw_input 。 然后，您需要查找word_List提供的word_List 。

while True:
   try:
       choose = int(raw_input("Which one?"))

       # Keep the key as a separate variable for faster reference
       key = word_List[choose - 1]

       # Use labels with the format function. It's easier to read and understand
       print '{label}: {text}'.format(label=key, text=myEngDict[key])

       # Be sure to have a break or return on success.
       return
   except ValueError: 
       # If someone provides 'cat', it will raise an error.
       # Inform the user and go back to the start.
       print 'Please provide an integer'
   except IndexError:
       # The user has provided a value above the length of word_List or 
       # less than one. Again, inform the user and go back to start.
       print 'You must enter a number between 1 and {c}'.format(c=len(word_List))

Answer 2

通過不更改太多代碼，您可以在choose函數后以相同的標識添加一個打印語句：

print ("%s : %s"%(word_List[choose-1], myEngDict[word_List[choose-1]]))
