7. Keyword arguments
A keyword argument passes a value by parameter name. Write parameter=value in the call:
name="Ada"is a keyword argument;nameis the parameter it fills.- Keyword arguments can be written in any order.
- A positional argument must come before keyword arguments:
describe("Ada", age=36). - You cannot pass the same parameter twice.
Coming from JavaScript? Python has named arguments at the call site (describe(age=36, name="Ada")). JS has no direct equivalent; the closest is passing an options object and destructuring it.
Pass arguments by name
Define describe(name, age) that prints <name> is <age> using an f-string. Call it with both keyword arguments: describe(name="Ada", age=36).

Keyword arguments can change order
Define describe(name, age) as above. Call it with the keywords in reverse order: describe(age=36, name="Ada"). The output is the same because each value is matched by name.
