 我必须评估一个文本文件，其中包含格式不正确的文章，我必须重新格式化。 第一步是删除句子中的所有额外空格。 我决定读入文件，然后将所有行放入一个字符串中，然后将包含句子的行放入单独的列表中。 现在我在决定如何删除列表中的多余空格时遇到困难，并且想知道是否可以使用内置方法删除多余的空格？ 
 
 以下是我列表中一个句子的例子： 
 
["Albuquerque is my     turkey and he's   feathered and    he's      fine, And    he"]
 
 和我到目前为止的代码： 
 
def remove_extra_whitespaces():
    fileList= []
    removeList= []
    infile= open("essay1.txt", 'r')
    for line in infile:
        if (len(line))>0:
            fileList.append(line.strip())

        else:
            fileList.append(line)
    print (len(fileList[4]))
    for k in range(len(fileList)):
        if (len(fileList[k]))>0:
            #" ".join(fileList[k])
            removeList.append(fileList[k])

I have to evaluate a text file that contains a poorly formatted essay that I must reformat. The first step is to remove all extra spaces in the sentences. I decided to read in the file and then put all the lines into a string and then I put the lines that contains sentences into its own separate list. Now I have trouble with deciding how to remove the extra spaces in the list and was wondering if theres a built in method that I can use to remove extra spaces?
 
Here is an example of a sentence in my list:
 
["Albuquerque is my     turkey and he's   feathered and    he's      fine, And    he"]
 
and the code I have so far :
 
def remove_extra_whitespaces():
    fileList= []
    removeList= []
    infile= open("essay1.txt", 'r')
    for line in infile:
        if (len(line))>0:
            fileList.append(line.strip())

        else:
            fileList.append(line)
    print (len(fileList[4]))
    for k in range(len(fileList)):
        if (len(fileList[k]))>0:
            #" ".join(fileList[k])
            removeList.append(fileList[k])
