| Python Idobject | Objeto Python |
id() es una función incorporada en Python 3, que devuelve la identidad de un objeto. La identidad es un entero único para ese objeto durante su vida útil. Esta es también la dirección del objeto en la memoria.
Argumento
objeto
El argumento object normalmente puede ser un int , float , str , list , dict , tuple , etc.
Ejemplo de código
a = 2
print(id(a)) #=> 140454723286976 (Values returned by id() might be different for different users)
b = 3
print(id(b)) #=> 140454723287008
c = 2
print(id(c)) #=> 140454723286976 (This is same as id(a) since they both contain the same value and hence have same memory address)
print(id(a) == id(b)) #=> False (since a and b have different values stored in them)
print(id(a) == id(c)) #=> True (since a and c have same values stored in them)
d = 1.1
e = 1.1
print(id(d) == id(e)) #=> True (since d and e have same values stored in them)
str1 = 'hello'
str2 = 'hello'
print(id(str1) == id(str2)) #=> True (since str1 and str2 have same values stored in them)
# For complex objects like lists, tuples, dictionaries etc. id() would give a unique integer even if the content of those containers is same.
tup1 = (1,1)
tup2 = (1,1)
print(id(tup1) == id(tup2)) #=> False
