Descripción
1. Datos
| List | Tuple | Set | Dictionary |
| List is a non-homogeneous data structure which stores the elements in single row and multiple rows and columns | Tuple is also a non-homogeneous data structure which stores single row and multiple rows and columns | Set data structure is also non-homogeneous data structure but stores in single row | Dictionary is also a non-homogeneous data structure which stores key value pairs |
| List can be represented by [ ] | Tuple can be represented by ( ) | Set can be represented by { } | Dictionary can be represented by { } |
| List allows duplicate elements | Tuple allows duplicate elements | Set will not allow duplicate elements | Set will not allow duplicate elements and dictionary doesn’t allow duplicate keys. |
| List can use nested among all | Tuple can use nested among all | Set can use nested among all | Dictionary can use nested among all |
| Example: [1, 2, 3, 4, 5] | Example: (1, 2, 3, 4, 5) | Example: {1, 2, 3, 4, 5} | Example: {1, 2, 3, 4, 5} |
| List can be created using list() function | Tuple can be created using tuple() function. | Set can be created using set() function | Dictionary can be created using dict() function. |
| List is mutable i.e we can make any changes in list. | Tuple is immutable i.e we can not make any changes in tuple | Set is mutable i.e we can make any changes in set. But elements are not duplicated. | Dictionary is mutable. But Keys are not duplicated. |
| List is ordered | Tuple is ordered | Set is unordered | Dictionary is ordered |
Creating an empty list l=[] | Creating an empty Tuple t=() | Creating a set a=set() b=set(a) | Creating an empty dictionary d={} |
2. Ejemplos
# Python3 program for explaining
# use of list, tuple, set and
# dictionary
# Lists
l = []
# Adding Element into list
l.append(5)
l.append(10)
print("Adding 5 and 10 in list", l)
# Popping Elements from list
l.pop()
print("Popped one element from list", l)
print()
# Set
s = set()
# Adding element into set
s.add(5)
s.add(10)
print("Adding 5 and 10 in set", s)
# Removing element from set
s.remove(5)
print("Removing 5 from set", s)
print()
# Tuple
t = tuple(l)
# Tuples are immutable
print("Tuple", t)
print()
# Dictionary
d = {}
# Adding the key value pair
d[5] = "Five"
d[10] = "Ten"
print("Dictionary", d)
# Removing key-value pair
del d[10]
print("Dictionary", d)
