코드 내성
코드 내성은 클래스, 함수 및 키워드를 검사하여 그것들이 무엇인지, 무엇을 하는지, 무엇을 알고 있는지 파악할 수 있는 능력입니다.
Python은 코드 내성을 위한 여러 함수와 유틸리티를 제공합니다.
help()
dir()
hasattr()
id()
type()
repr()
callable()
issubclass()
isinstance()
__doc__
__name__
가장 중요한 것은 종종 help 함수인데, 다른 함수가 무엇을 하는지 찾는 데 사용할 수 있기 때문입니다.
Exercise--------
주어진 Vehicle 객체의 모든 속성 목록을 출력하십시오.
# Use the help function to see what each function does.
# Delete this when you are done.
help(dir)
help(hasattr)
help(id)
# Define the Vehicle class.
class Vehicle:
name = ""
kind = "car"
color = ""
value = 100.00
def description(self):
desc_str = "%s is a %s %s worth $%.2f." % (self.name, self.color, self.kind, self.value)
return desc_str
# Print a list of all attributes of the Vehicle class.
# Your code goes here
# Define the Vehicle class
class Vehicle:
name = ""
kind = "car"
color = ""
value = 100.00
def description(self):
desc_str = "%s is a %s %s worth $%.2f." % (self.name, self.color, self.kind, self.value)
return desc_str
# Print a list of all attributes of the Vehicle class.
print(dir(Vehicle))
test_output_contains("['__doc__', '__module__', 'color', 'description', 'kind', 'name', 'value']")
test_student_typed("print")
success_msg("Very nice!")
