Python：如何从数组中的数组中提取项目？

我有两个数组，其中一个是包含数组的数组。

wordsEn = ["why", "because", "go"] 
wordsDe = [["warum"], ["weil", "da"], ["los", "gehen"]]

我的代码是

step = 0
size = 3
while step < size:
    word = input("Enter name of word: ")
    print("your word was " + word)
    if word in wordsEn:
       pos = wordsEn.index(word)
       print(wordsDe[pos])
       step = step + 1
    else:
        print("word not found.")

if i ask it print wordsDe[1] it prints ['weil', 'da']

我如何使其像列表一样打印
