Function Parameters Assigned with Object References

Q

Is it true that all function parameters are assigned with object references in Python?

✍: FYIcenter.com

A

Yes, all function parameters are assigned with object references in Python. You modify referenced data objects to share data with the calling statement.

Here is a good example of modifying the data object referenced by the parameter:

IndentationError: unexpected indent
>>> def load(name,age,user):
...     profile = {"name":name,"age":age}
...     user["profile"] = profile
...
>>> guest = {}
>>> load("Joe",25,guest)
>>> guest
{'profile': {'name': 'Joe', 'age': 25}}

Note that both variables "guest" and "user" are referring to the same data object.

'@...' Function Decorators
What are function decorators in Python? A function decorator is shorthand notation to replace a function with a new version transformed by a wrapper function. A function decorator can be specified using the following syntax: @decorator_wrapper_function def func(): ... Above Python code is actually e... 2018-05-08, ∼2816🔥, 0💬

What Is Wrapper Function
What is a wrapper function in Python? A wrapper function in Python is a function that takes an old function as input parameter and returns a new function. The new function should have the same parameter list and return type. If you call the new function, it will perform the same task as the old func... 2018-02-08, ∼2655🔥, 0💬

Calling Function with Keyword Parameters
How to call a function with keyword parameters instead of positional parameters? By default, you should call a function with a list of data objects as positional parameters matching the parameter list in the function "def" statement. But you can also call a function with name value pairs as keyword ... 2022-10-26, ∼1939🔥, 0💬

Function Parameter Default Expression Executed Only Once
Is it true that the function parameter default expression is only executed once in Python? Yes, the function parameter default expression is only executed once in Python when the "def" statement is interpreted.
