Vim Jedi Initalize

Question

I was trying initalize jedi-vim. But i am getting "Not an editor command: Plugin 'davidhalter/jedi-vim'" error. I tried Plug , plug , Plugin , plugin but still getting the same error. README of jedi-vim repository says:

Add the following line in your ~/.vimrc    
Plugin 'davidhalter/jedi-vim'

this is .vimrc file:

Plugin 'davidhalter/jedi-vim'
let g:jedi#auto_initialization = 0
let g:jedi#auto_vim_configuration = 0
let g:jedi#use_tabs_not_buffers = 1
let g:jedi#use_splits_not_buffers = "left"
let g:jedi#popup_on_dot = 1
let g:jedi#popup_select_first = 0
let g:jedi#show_call_signatures = "1"
let g:jedi#goto_command = "<leader>d"
let g:jedi#goto_assignments_command = "<leader>g"
let g:jedi#goto_stubs_command = "<leader>s"
let g:jedi#goto_definitions_command = ""
let g:jedi#documentation_command = "K"
let g:jedi#usages_command = "<leader>n"
let g:jedi#completions_command = "<C-Space>"
let g:jedi#rename_command = "<leader>r"
let g:jedi#environment_path = "/usr/bin/python3.9"
let g:jedi#environment_path = "venv"
let g:jedi#completions_enabled = 0

and i have downloaded jedi-vim , if you think you haven't downloaded the jedi-vim.
How can i solve this.
i was tried with pathogen. this is .vimrc

xecute pathogen#infect()
syntax on
filetype plugin indent on


let g:jedi#auto_initialization = 1

And i am getting Omni completion (^O^N^P) Pattern not found error. I saw a question in stack overflow but i couldn't understand

Plug, plug and Plugin are presumably commands for different Plugin managers that you most likely aren't using.

I might suggest you try using vim-plug as I found it relatively straightforward for a beginner to set up. From vim-plug's README, copy/paste and run the relevant shell command for your operating system and version of vim (If you're using Linux or Mac, it's curl command listed under Unix) and add the following to your .vimrc

" Specify a directory for plugins
" - For Neovim: stdpath('data') . '/plugged'
" - Avoid using standard Vim directory names like 'plugin'
call plug#begin('~/.vim/plugged')

Plug 'davidhalter/jedi-vim'

" Initialize plugin system
call plug#end()

Resource your .vimrc (or just close and open vim again) and run :PlugInstall from vim command mode.
