连接两个不同列表中的字符串 [英] concatenate two strings that are in different lists

问题描述

我需要连接两个不同列表中的字符串，并检查输出字符串是否在字典中。我尝试过的代码是：

I need to concatenate two strings that are in different lists and check if the output string is in a dictionary. The code I've tried is:

x=['casa','lo','pre','computer']
y=['music','sun','ve','sident','house']
dic=['sunday','love','president','house','computer']
text=[]
errors=[]
iter_y=iter(y)
iter_x=iter(x)

for i in iter_x:
    if i in dic:
        text.append(i)
    else:
        try:
            concatenated= i + next(iter_y)
            if concatenated in dic:
                text.append(concatenated)
      except StopIteration:
          continue
        else:
            errors.append(i)
   print (text)

此代码仅返回x和y共同的单词（计算机）。我期望的输出是x = [love，President，computer]，即在输出中串联了love and President的字样。

This code is returning only the word that is common to x and y ('Computer'). My desired output is x=[love, president, computer] That is, with the words love and president concatenated in the output.

推荐答案

使用您的方法，您需要在 y 上重置迭代器每次尝试在 x 中使用新值时。

With your approach, you need to reset the iterator over y each time you try a new value in x.

可能更像这样：

for i in x:
  if i in dic:
    text.append(i)
  else:
    for j in y:
      concatenated = i + j
      if concatenated in dic:
        text.append(concatenated)

y中j的 尝试 y ，否则它每次都会移动，并且永远不会回头。

The for j in y tries all the things in y, otherwise it moves on each time, and never looks back.
