Python Eliciting Tuples from Function Argument Types Example Analysis

This article is an example of Python eliciting tuples from function parameter types. Shared for your reference, as follows:

Custom Functions: Special Arguments

def show(name="jack", *info):
  print(name) #jack
  print(info) #(22, 'male')
show("jack",22,"Male.")

it can be seen22, "Male"All grouped into the second argument of the function*info。

We can see that printing thisinfoParameters result in: parenthesis-wrapped form.

Special parameter upgrades for functions

See above for function arguments*xxxIn this form, take a look below at 2*The form of the

def show(name="jack", **info):
  print(name) #jack
  print(info) #{'sex': 'male', 'age': 22}
show("jack",age=22,sex="Male.")

**infoNote that at this point it's 2*The function prints a string that looks like a json structure. The function prints internally to get a string that looks like a json structure.

What the heck are the three parameters? What's the difference?

Let's look at this with Pytone's built-in function type

def show(name="jack",*info1, **info2):
 print(type(name))
 print(type(info1))
 print(type(info2))
show("jack",22,"Male.",age=22,sex="Male.")

Guess: what would be the type of parameter to print these 3?

<class 'str'>
<class 'tuple'>
<class 'dict'>

nameis a string.*info1is a tuple.**info2It's the dictionary.

Tuple

(22, 'Male')

element in the form of a parenthesis wrapped around it.
