Available module lineinfile - Concatenate quotes and double quotes

I'm trying to add a string containing single quotes and double quotes and I can't seem to do it for an expired hour ...

vars:
  line1: "a=\\\"a'b'c\\\""
  line2: 'a="a\''b\''c"'
tasks:
- name: lineinfile test
  lineinfile: dest=/tmp/tmp line={{item}}
  with_items:
    - "{{line1}}"
    - "{{line2}}"

      

        
        
        
      

    

search string a="a'b'c"

content / tmp / tmp

a="abc"
a=a'b'c

      

        
        
        
      

    

so that's the trick. ideas?
