I am having some issue while creating VM from ansible – CentOS

I am using Ansible version2. 2.9.9 and Python version 3.6.9; and I have installed requests modules too but every time I run my code I ger error of Mo Module name requests, I have changed the ansible_pythin_interpreter to python 3 as well but it didn’t heled me. Please go through my code and help me here.

Traceback (most recent call last):
  File "/tmp/ansible_vmware_guest_payload_evshxlga/ansible_vmware_guest_payload.zip/ansible/module_utils/vmware.py", line 24, in <module>
    import requests
ImportError: No module named 'requests'

    "msg": "Failed to import the required Python library (requests) on Python /user/bin/python. Please read the module documentation and install it in the appropriate location. If the required library is installed, but Ansible is using the wrong Python interpreter, please consult the documentation on ansible_python_interpreter"

I have uploaded my code as well
