List, Tuples, Set and Dictionary
# Empty Lists - Mutable
empty_list = []
empty_list = list()
# Empty Tuples - Immutable
empty_tuple = ()
empty_tuple = tuple()
# Empty Sets - throw away duplicates or membership test
empty_set = set()
# Empty Dict - Key Value pairs
empty_dict = {} # This isn't right! It's a dict
Examples |
| list_1 = ['History', 'Math', 'Physics', 'CompSci'] |
| |
| print(list_1) |
|
Update list |
| list_1[0] = 'Art' |
|
|
| #tuple
tuple_1 = ('History', 'Math', 'Physics', 'CompSci') |
| print(tuple_1) |
| |
| |
| # Sets |
| cs_courses = {'History', 'Math', 'Physics', 'CompSci'} |
|
|
| print(cs_courses) |
|
|
| # Dictionary |
| student = {'name': 'John', 'age': 25, 'courses': ['Math', 'CompSci']}
for key, value in student.items(): print(key, value) |
