split（）读取文件中的字符串

Question

名称为sketch1.txt

的文件的内容

Man: Is this the right room for an argument?
Other Man: I've told you once.
Man: No you haven't!
Other Man: Yes I have.
Man: When?
Other Man: Just now.
Man: No you didn't!

代码：

try:
     def read_file( ):
          data = open('C:\\Users\\Adam\\Documents\\eBook\\PythonData\\sketch1.txt', 'r')
     print ("---- read all---")
     for read_lines in data:
          try:
               if read_lines.find(':') != -1:
                    (role, line_said) = read_lines.split(":", 1)
                    print(role +' says ' +line_said)
               else:
                    print(read_lines)
          except:
               pass

except:
     print("data file is missing")

结果： 工作一次，但不是每次我跑

---- read all---
Man says  Is this the right room for an argument?

Other Man says  I've told you once.

Man says  No you haven't!

Other Man says  Yes I have.

错误： 在大多数情况下，我最终只收到一份印刷声明

  ---- read all---

Answer 1

您的示例中似乎缺少一些代码。例如，我不明白为什么你可以循环数据而不在for循环的范围内定义它（它只在read_file函数中定义，从不调用）。此外，代码是不必要的复杂，所以除非有任何特定的方式与拆分，我做如下：

with open('C:\\Users\\Adam\\Documents\\eBook\\PythonData\\sketch1.txt', 'r') as f:
    for line in f:
        print line.replace(':', ' says', 1)

这也将在您完成阅读后关闭文件（由于with语句）。
