ConfigParser overwriting the content of config file

Question

I am having a problem when writing to a config file. I have two Python scripts that read and write to the same file. the problem is when I write to it from one script it overwrites the content from the other script.

Here is my code:

authfile = "Users/.ahs" # .ahs is a hidden file
config = ConfigParser.ConfigParser()
tmpfile = open(authfile, "w+")
config.add_section(s)
config.set(s, k, t)
config.write(tmpfile)
tmpfile.close()

Answer 1

w+ truncates the file when it opens, are you sure you didn't mean a or a+ ?
