从 Python 文件中选择特定单词

Question

I am completly new to python, and I need a specific answer. I need to print only the authors name from a list of reference in a file by using python code.

Answer 1

You can use a brute-horse algorithm to check if each word in the file is the last name of an author.

bookFile = open("someBook.txt", "r"); ### replace with the actual txt file location

fullText = bookFile.read(); ### reads the text in bookFile
words = fullText.split(' '); ## an array of all of the words in the bookFile

bookFile.close();

authorLNList = [ "Rowling", "Tolkien", "Twain", "Martin" ]; ### replace with the actual reference list of authors

for word in words: ### iterates over each word in the book
    if word in authorLNList: ### if the word is the last name of an author
        print( str( word ) );

This only checks for last names of authors, but you can easily check for multi-word strings as well with a bit of editing.
