이제 파이썬 기초문법+심화과정을마치고
Django과정을 시작했다.
배우고 느낀점은 Java -Spring 보다 훨씬 쉽고 직관적이며 다양한기능들이 있다는걸 알수있엇다.
맨처음부터 파이썬을 배웠으면 어땟을까 라는 생각이들기도한다.
다음은
타임어택 첫 수업을했다
총 네문제
1번문제
a = 10
def test1():
b = 20
def test2():
print(a)
print(b)
test1()
test2()
# 실행이 잘 될까요?
# 실행이 되지 않는다면 어떤 에러가 발생할까요?
#8번줄에서 에러가갑니다
#a는 전역변수이고 b는 test1함수에서만 사용할수있는 지역변수이기때문에
#test2에서는 a변수만 사용이가능하고 b함수는 사용이 불가능합니다.
쉬움
# mutable
a={1,2,3,4,5,6,}
b=['asd','sdf','fgd','gew4465']
c={'age ':19,'gender ': 'man'}
print(type(a)) # set
print(type(b)) #list
print(type(c)) #dict
# immutable
a=10
b=10.56
print(type(a)) # int
print(type(b)) #float
2번문자 mutable 과 immutable 의종류
쉬움
3번문제
def get_even_numbers(numbers):
result = [ x for x in numbers if x%2==0]
return result
def get_some_numbers(numbers):
result = []
result = list(filter(lambda x: x%3 ==0 and x%15 !=0,numbers))
result =list(map(lambda x: x*10,result))
return result
def main():
numbers = [x for x in range(1,1001)] # 1 ~ 10000
even_numbers = get_even_numbers(numbers)
some_numbers = get_some_numbers(numbers)
print(even_numbers) # [2, 4, 6, ...]
print(some_numbers) # [30, 60, 90, 120, 180, ...]
main()
각각의 함수에 알맞는 공식 적기
짝수구하는 방법은 쉬웠고
(3의배수 +15의배수아닌수) x10 출력하기
순서가 다르긴했지만 답은 맞았다.
4번문제

예전에못풀었던 문제인데 이번기회에 한번더 복습할수 있는 기회였다
