input.txt is just a delimited file with text required for my script to process. My subfuncx functions would require entire line and each of these functions have different objectives with each of these variables. Hence the best way is to pass the entire line to each of these subfunctions but that would mean that I will have to write split for every variable I require. Is there any better way to do that?
Functions should do one and preferable one thing only. An indication that a function is doing too much is the amount of passed arguments that it has. Thus said, going along with your design choice of subfuncX, here's an example that might show some way of handling the passing of arguments, and function calls.

Code:
#!/usr/bin/env python

def funct1(a):
    print("funct1 showing argument {}".format(a[0]))


def funct2(a):
    print("funtct2 showing arguments {} and {}".format(a[0], a[1]))


def funct3(a):
    print("funct3 showing arguments {}, {} and {}".format(a[0], a[1], a[2]))


funct_cluster = [ funct1, funct2, funct3 ]

def main(ar):
    for funct in funct_cluster:
        funct(ar)

if __name__ == "__main__":
    with open('input.txt', 'r') as f:
        for line in f:
            arguments = line.rstrip().split('=')
            main(arguments)

PYCENTRAL()															       PYCENTRAL()

NAME

       pycentral - register and build utility for Python packages

SYNOPSIS

       pycentral [-h] [-v] <cmd> [<cmd options>] [<args>]

DESCRIPTION

       pycentral
	provides support for installing python modules independent
	of the current installed Python version and handling
	byte-compilation and -removal tasks in installation scripts.

OPTIONS

       -v, --version
	      Limit the output to the version numbers of the python versions.

       -h, --help
	      Print a help text.

       pycentral has the following sub commands. For fine grained help, call: pycentral <cmd>.

       bccompile
	      Byte compile .py files in a package.

       bcremove
	      Remove the byte compiled .py files.

       list   List all managed files.

       pkginstall
	      Make a package available for all supported runtimes.

       pkgprepare
	      Prepare a package for all supported runtimes.

       pkgremove
	      Remove a package installed for all supported runtimes.

       pkglist
	      List pycentral-managed files of a package for all supported runtimes.

       rtinstall
	      Make installed packages available for this runtime.

       rtremove
	      Remove packages installed for this runtime.

       updatedefault
	      Update the default python version.

       debhelper
	      move files to pycentral locaation, variable substitutions (called by dh_pycentral).

       pycentraldir <package>
	      Show the installation directory used by pycentral for <package>.

       showdefault
	      Show default python version number. Deprecated, use pyversions(1)

       showsupported
	      Show the supported python versions. Deprecated, use pyversions(1)

       showversions
	      Show version numbers of supported python versions.  Deprecated, use pyversions(1) dh_pycentral, should not be called directly).

       version
	      Show the pycentral version.

FILES

       /etc/python/debian_config   is	searched   for	 the   attribute   overwrite-local.    If   set   to   1,   or	True,  existing  files	in
       /usr/lib/pythonX.Y/*-packages are overwritten with symbolic links to the pycentral install area. The default is to abort  the  installation
       of  a  package,	when files already exist. This behaviour may be useful, when python libraries were manually installed into this directory.
       The attribute byte-compile can be set to a comma separated list of the values standard and optimze to indicate how files  should  be  byte-
       compiled.
