The example you are looking for is provided on: https://www.python-ldap.org/en/python-ldap-3.3.0/reference/ldif.html. Scroll to the end of the page.

Goes like this:

import sys
from ldif import LDIFParser,LDIFWriter

SKIP_DN = ["uid=foo,ou=People,dc=example,dc=com",
    "uid=bar,ou=People,dc=example,dc=com"]

class MyLDIF(LDIFParser):
    def __init__(self,input,output):
    LDIFParser.__init__(self,input)
    self.writer = LDIFWriter(output)

def handle(self,dn,entry):
    if dn in SKIP_DN:
       return
    self.writer.unparse(dn,entry)

parser = MyLDIF(open("input.ldif", 'rb'), sys.stdout)
parser.parse()
