web.py How to export dollar signs in a template _python

Because web.py has defined the "$" symbol bit delimiter in the template, special handling is required in the template if the dollar sign is to be used.

If I want to output the "$name" string in the template:

Copy Code code as follows:

$name

Error

$name is considered a variable instead of being treated as an HTML string. If you want to output the "$name" string You must write this:

Copy Code code as follows:

$ $name

Save to run the correct output.
Especially when mixing with jquery, be aware of it. Such as:

Copy Code code as follows:

$ ("id"). html ("cloud-dwelling community");

To be modified into:

Copy Code code as follows:

$$ ("id"). html ("cloud-dwelling community");

So that you can use it.
Because Python is a server-side language, JS is the client language. Server-side language finally put:

Copy Code code as follows:

$$ ("id"). html ("cloud-dwelling community");

Translate into:

Copy Code code as follows:

$ ("id"). html ("cloud-dwelling community");

Then throw it to the client instead of jquery and use the double dollar sign "$$" ("id"), and don't get the idea wrong.
