Basic Python

ทบทวน Python

def setup():
    a = [-1,-2,3,5,8,4,10]
    print(calc_postive_sum(a))


def calc_postive_sum(a):
    sum = 0
    for i in a:
        if(i > 0):
            sum+=i
     
    return sum

setup()

การใช้ Class

class Person:
    def __init__(self,name,age):
        self.name=name
        self.age=age
    def display(self):
        print("Name:",self.name)
        print("Age:",self.age)

def setup():
    person1 = Person("John",20)
    person2 = Person("Jan",19)
    people = [person1,person2]
    for i in people:
        i.display()
setup()
     

built-in data structure

List

• Queue
• append
• popleft (ต้อง import collections.deque )
• Stack
• append
• pop

Sets

def setup():

   a = [5,2,3,5,5,6,8,6,5,2]

   a = remove_duplicate(a)

   print(a)

   

def remove_duplicate(a):

   return list(set(a))

setup()
