I have the following string:

nginx_conf = '''
server {
 listen 80;
 server_name dev.{project_url};

 location / {
 include /etc/nginx/proxy.conf;

 location /media {
 alias /home/mariano/PycharmProjects/{project_name}/{project_name}/media;
 expires 30d;

 location /static {
 alias /home/mariano/PycharmProjects/{project_name}/{project_name}/static;
 expires 30d;

 error_page 500 502 503 504 /50x.html;
 location = /50x.html {
 root html;

And I want to format like this:

context = {


but since the string have { i can't. Is there a way to solve this?

Are you in full control of the source string? You can escape the braces as explained here:

If you're not in full control (eg if it comes from a user's input), or if you don't like the idea of doubling all your braces, you could switch to percent-formatting, or some other form of interpolation. But the easiest would be to simply escape them.

This isnt a huge issue, but I am wondering. I am running Mac OS X, I tried to configure with --with-valgrind and this is the error that I got:

configure: error: Valgrind support requested but headers not available

Now, I have valgrind installed, so it should work, yes?If someone has any extra info on this, Id appreciate it.

I read the online help about string. It lists string constants, string formatting, template strings and string functions. After reading these, I am still puzzled about how to use the string module.

Could you show me a few example about this module?
