How to remove spaces while writing in INI file- Python

I am using a file and i have one section named DIR in which it contain the paths.
EX:

[DIR]
DirTo=D:\Ashish\Jab Tak hai Jaan
DirBackup = D:\Parser\ERICSSON_CSCORE_STANDARD_VMS\Backup
ErrorDir = D:\Parser\ERICSSON_CSCORE_STANDARD_VMS\Error

CombinerDir = D:\Parser\ERICSSON_CSCORE_STANDARD_VMS\Combiner
DirFrom=D:\Parser\ERICSSON_CSCORE_STANDARD_VMS\In
PidFileDIR = D:\Parser\ERICSSON_CSCORE_STANDARD_VMS\Pid
LogDir = D:\Parser\ERICSSON_CSCORE_STANDARD_VMS\Log
TempDir = D:\Parser\ERICSSON_CSCORE_STANDARD_VMS\Temp


Now I want to replace the paths which I have done it but when I replaced its giving me spaces after and before the delimiter in the newly written
.ini
file. For example:
DirTo = D:\Parser\Backup
. How I remove these spaces?

Code:

def changeINIfile():
config=ConfigParser.RawConfigParser(allow_no_value=False)
config.optionxform=lambda option: option
cfgfile=open(r"D:\Parser\ERICSSON_CSCORE_STANDARD_VMS\Windows\opx_PAR_GEN_660_ERICSSON_CSCORE_STANDARD_PM_VMS_MALAYSIA.ini","w")
config.set('DIR','DirTo','D:\Ashish\Jab Tak hai Jaan')
config.optionxform=str
config.write(cfgfile)
cfgfile.close()

Answer

Here is the definition of RawConfigParser.write:

def write(self, fp):
    """Write an .ini-format representation of the configuration state."""
    if self._defaults:
        fp.write("[%s]\n" % DEFAULTSECT)
        for (key, value) in self._defaults.items():
            fp.write("%s = %s\n" % (key, str(value).replace('\n', '\n\t')))
        fp.write("\n")
    for section in self._sections:
        fp.write("[%s]\n" % section)
        for (key, value) in self._sections[section].items():
            if key != "__name__":
                fp.write("%s = %s\n" %
                         (key, str(value).replace('\n', '\n\t')))
        fp.write("\n")

As you can see, the %s = %s\n format is hard-coded into the function. I think your options are:

  1. Use the INI file with whitespace around the equals
  2. Overwrite RawConfigParser's write method with your own
  3. Write the file, read the file, remove the whitespace, and write it again

If you're 100% sure option 1 is unavailable, here's a way to do option 3:

def remove_whitespace_from_assignments():
    separator = "="
    config_path = "config.ini"
    lines = file(config_path).readlines()
    fp = open(config_path, "w")
    for line in lines:
        line = line.strip()
        if not line.startswith("#") and separator in line:
            assignment = line.split(separator, 1)
            assignment = map(str.strip, assignment)
            fp.write("%s%s%s\n" % (assignment[0], separator, assignment[1]))
        else:
            fp.write(line + "\n")
