Python list [Sequence type]

[sequence type]

 

1. list type

days = [] <= 빈 list 생성

days = ["Mon", "Tue", "Wed", "Thu", "Fri"] <= 리스트에 데이터 선언

 

<list 내의 값 확인>

 

print("Mon" in days) => True

print("Men" in days) => False

 

print(days[2]) => Wed

 

<list length 확인>

print(len(days)) => 5

 

<list 값 추가>

 

print(len(days)) =>5

days.append("Sat")

print(len(days)) =>6

 

<list 값 역변환 그리고 삭제>

 

print(days) => ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'] 

 

days.reverse() : list 역변환

print(days) => ['Sat', 'Fri', 'Thu', 'Wed', 'Tue', 'Mon'] 

 

del days[2] : list index 요소 delete

print(days) => ['Sat', 'Fri', 'Wed', 'Tue', 'Mon'] 

 

days.remove("Tue") : list value remove

print(days) => ['Sat', 'Fri', 'Wed', 'Mon']

 

days.clear() : list remove all items

print(days) => []
