Django How to redirect only example.com to https and *.example.com to http?

I need http://example.com to redirect to https://example.com. Whereas http://www.example.com, http://api.example.com must not redirect i.e, subdomains need not redirect to https.

I can understand the configuration here by looking at it. But don't know to move further. Please help me.
My configuration so far is:

sites-available/default.py

upstream app_server {
server unix:/home/django/gunicorn.socket fail_timeout=0;
}

server {
server_name example.com www.example.com cloud.example.com api.example.com;
listen 80;
return 301 https://example.com$request_uri;
}

server {
server_name example.com www.example.com cloud.example.com api.example.com;

listen 443; # <-

ssl on; # <-
ssl_certificate /etc/ssl/example_cert_chain.crt; # <-
ssl_certificate_key /etc/ssl/example.key; # <-
#listen 80 default_server;
#listen [::]:80 default_server ipv6only=on;

root /usr/share/nginx/html;
index index.html index.htm;

client_max_body_size 4G;
server_name _;

keepalive_timeout 5;

# Your Django project's media files - amend as required
location /media {
alias /home/django/django_project/media;
}

# your Django project's static files - amend as required
location /static {
alias /home/django/django_project/static/;
}

# Proxy the static assests for the Django Admin panel
location /static/admin {
alias /usr/lib/python2.7/dist-packages/django/contrib/admin/static/admin/;
}

location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto https; # <-
proxy_set_header X-Forwarded-Protocol $scheme;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_buffering off;

proxy_pass http://app_server;
}

}

Edit this:

server {
server_name example.com www.example.com cloud.example.com api.example.com;
listen 80;
return 301 https://example.com$request_uri;
}


Into:

server {
server_name example.com www.example.com cloud.example.com api.example.com;
listen 80;
if ($http_host = "example.com") {
rewrite ^ https://example.com$request_uri permanent;
}
}


nginx[28994]: nginx: [emerg] unknown directive "if($http_host" in /etc/nginx/sites-enabled/django:8
