Disable automatic whitespace marking in red

Question

I am experiencing a behavior as depicted in the picture below: vim marks the redundant spacing in red.

I would like to completely remove this behavior. At the moment my .vimrc file reads as:

set nocompatible              " required
filetype off                  " required

" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()

" alternatively, pass a path where Vundle should install plugins
"call vundle#begin('~/some/path/here')



" let Vundle manage Vundle, required
Plugin 'gmarik/Vundle.vim'
Plugin 'dense-analysis/ale'
Plugin 'sheerun/vim-polyglot'
Plugin 'tmsvg/pear-tree'
Plugin 'godlygeek/tabular'
Plugin 'preservim/nerdtree'
Plugin 'arcticicestudio/nord-vim'
Plugin 'morhetz/gruvbox'
" All of your Plugins must be added before the following line"
call vundle#end()            " required
filetype plugin indent on    " required

"Automaticaly open nerdTREE"
autocmd StdinReadPre * let s:std_in=1
autocmd VimEnter * if argc() == 0 && !exists("s:std_in") | NERDTree | endif
nmap <F1> :NERDTreeToggle<CR>

"Python settings"
au BufNewFile, BufRead *.py
    \ set tabstop=4
    \ set softtabstop=4
    \ set shiftwidth=4
    \ set textwidth=79
    \ set expandtab
    \ set autoindent
    \ set fileformat=unix
    \ set encoding=utf-8

colorscheme gruvbox
set background=dark
let g:gruvbox_contrast_dark = 'soft'
nnoremap <C-Left> :tabprevious<CR>
nnoremap <C-Right> :tabnext<CR>    

At some point I had this part of code which I think precisely initialized such behavior:

au BufRead,BufNewFile *.py,*.pyw,*.c,*.h match BadWhitespace /\s\+$/

But since then I have purged vim from my computer with all other info as well, reinstalled it but the problem still is here.

I believe this is caused by an option in the python highlighting used by your vim-polyglot plugin. You can disable this by setting the following variable in your vimrc:

let g:python_highlight_space_errors = 0
