localeTitle: Python Idobject
|
||
---
|
||
`id()` - встроенная функция в Python 3, которая возвращает _идентификатор_ объекта. _Идентификатор_ является уникальным целым для этого объекта в течение его жизни. Это также адрес объекта в памяти.
|
||
|
||
## аргументация
|
||
|
||
#### объект
|
||
|
||
Аргументом `object` обычно может быть `int` , `float` , `str` , `list` , `dict` , `tuple` и т. Д.
|
||
|
||
## Образец кода
|
||
```
|
||
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
|
||
```
