how to read ,increment by one and write back value to a network file location

python

Solution

Backslashes escape special Characters, in your case '\f': form-feed and '\b': bell. You have to escape the backslash with another backslash or use the r''-Syntax. Next problem: you don't read the file, you only rename the object. If you would read the object, you would have a string and not a number, and if you would convert the string to a number you couldn't write it because it's not a string. All in all you get this:

with open(r'\\network\files\build_ver.txt','r+') as f:
    value = int(f.read())
    f.seek(0)
    f.write(str(value + 1))
