字數統計Python 3.3程序中的可迭代錯誤

Question

我正在嘗試完成一個簡單的單詞計數程序，該程序可以跟蹤連接文件中的單詞，字符和行數。

   # This program counts the number of lines, words, and characters in a file, entered by the user.
   # The file is test text from a standard lorem ipsum generator.
   import string
   def wc():
      # Sets the count of normal lines, words, and characters to 0 for proper iterative operation.
        lines = 0
        words = 0
        chars = 0
        print("This program will count the number of lines, words, and characters in a file.")
       # Stores a variable as a string for more graceful coding and no errors experienced previously. 
       filename =("test.txt")
       # Opens file and stores it as new variable, and loops through each line once the connection   with file is made.
       with open(filename, 'r') as fileObject:
             for l in fileObject:
                # Splits text file into each individual word for word count.
                words = l.split()

                lines += 1
                words += len(words)
                chars += len(l)
        print("Lines:", lines)
        print("Words:", words)
        print("Characters:", chars)

    wc()

    while 1:
        pass

現在，如果一切順利，則應該打印文件中的行，字母和單詞的總數，但是我得到的只是以下消息：

“單詞+ = len（words）TypeError：'int'對象不可迭代”

怎么了？

解決了！ 新代碼：

    # This program counts the number of lines, words, and characters in a file, entered by the user.
    # The file is test text from a standard lorem ipsum generator.
    import string
    def wc():
        # Sets the count of normal lines, words, and characters to 0 for proper iterative operation.
        lines = 0
        words = 0
        chars = 0
        print("This program will count the number of lines, words, and characters in a file.")
        # Stores a variable as a string for more graceful coding and no errors experienced previously. 
        filename =("test.txt")
        # Opens file and stores it as new variable, and loops through each line once the connection with file is made.
        with open(filename, 'r') as fileObject:
            for l in fileObject:
                # Splits text file into each individual word for word count.
                wordsFind = l.split()

                lines += 1
                words += len(wordsFind)
                chars += len(l)
                 print("Lines:", lines)
                 print("Words:", words)
                 print("Characters:", chars)

    wc()

    while 1:
        pass

看來您正在使用變量名words進行計數，還使用了l.split()的結果。 您需要通過使用不同的變量名稱來區分它們。
