The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Appending file contents to a new file

Asked by sara_bellum in Python Scripting Language, Linux, Linux Programming

Tags: ,

I'm just starting out with Python but I'm stuck already and can't proceed unless I understand how this works.  I'm trying to append the contents of two files to a new file.  Each of the two source files has only a few simple lines of text (words separated by spaces) with Unix line returns, but no commas or other delimiters (I will try to work with more complex files later).  

I understand that these strings are read in as lists but cannot find a way to print lists that are read from a file. I tried using "for line in src1:" followed by a print statement but got a syntax error.  My most recent attempt at a script is attached below.  The errors are:  

File "./test.py", line 11, in ?
    print src1.read(output1)
TypeError: an integer is required

File "./test.py", line 12, in ?
    src1.write(output1)
TypeError: argument 1 must be string or read-only character buffer, not list

I don't think I should need to define a method unless I'm trying to strip quotation marks, line returns or white spaces.  Let me know what I'm missing, thanks
