What does "|" sign mean in Django?

Question

I often see something like that: something.property|escape

---

something is an object, property is it's string property. escape - i don't know :)
What does this mean? And what min python version it is used in?

EDIT: The question was asked wrongly, it said "What does | mean in Python", so the bitwise or answers are correct, but irrelevant, please do not downvote them

Answer 1

It's a bitwise "or". It means escape if the property doesn't exist/is null.

Answer 2

obj.property|escape is the way to apply the escape filter in a template, which will HTML escape the string representation of that property.

Answer 3

| is the bitwise "or" operator, most commonly used, these days, to combine options (though that isn't particularly "pythonic"). An example:

# Creates a dialog with "Yes" and "No" buttons in a fictional widget set.
result = Widgets.Dialog("Ex-parrot?", Widgets.YES | Widgets.NO)

It is sometimes confused with ||, which is the logical "or" operator in other popular languages, and is often used to provide an alternative or default for a value which may be missing or unset (this is considered "pythonic"). However, the logical "or" operator in python is simply or. Example:

# Uses a default value if one isn't provided on the command line
x = sys.argv[1] or 0

Answer 4

The pipe character indicates that you want to send the results of the left hand side to the filter defined on the right side. The filter will modify the value in some way.

The 'escape' filter is just one of many.

The list of built in filters can be found here: Django Documentation - Built-in filters reference

In a django template the | character definitely does not mean the 'bitwise OR' operator.
