Last Updated :

In this article, we are going to see how to find and print the address of the Python variable.
It can be done in these ways:
- Using id() function
- Using addressof() function
- Using hex() function
Method 1: Find and Print Address of Variable using id()
We can get an address using id() function, id() function gives the address of the particular object.
Syntax: id(object)
where, object is the data variables.
Here we are going to find the address of the list, variable, tuple and dictionary.
Python3
a = [ 1 , 2 , 3 , 4 , 5 ]
print ( id (a))
a = 12
print ( id (a))
a = ( 1 , 2 , 3 , 4 , 5 )
print ( id (a))
a = { 'a' : 1 , 'b' : 2 }
print ( id (a))
|
Output:
140234866534752
94264748411744
140234904267376
140234866093264
Method 2: Find and Print Address of Variable using addressof()
we can also get memory addresses using these functions, ctypes is a foreign function library for Python. It provides C-compatible data types and allows calling functions in DLLs or shared libraries.
Syntax:addressof(c_int(object))
where object is the data variables
Example: Python program to get the memory address of a variable.
Python3
from ctypes import c_int, addressof
a = 44
print (addressof(c_int(a)))
|
Output:
140234866278064
Method 3: Find and Print Address of Variable using hex()
Here we will call the hex(address) function, to convert the memory address to hexadecimal representation.
Syntax: hex(id(object))
where,
- hex() is the memory hexadecimal representation to the address
- id is used to get the memory of the object
- object is the data
Example: Python program to get the memory address in hexadecimal representation.
Python3
a = [ 1 , 2 , 3 , 4 , 5 ]
print ( hex ( id (a)))
a = 12
print ( hex ( id (a)))
a = ( 1 , 2 , 3 , 4 , 5 )
print ( hex ( id (a)))
a = { 'a' : 1 , 'b' : 2 }
print ( hex ( id (a)))

Output:
0x7fba9b0ae8c0
0x5572da858b60
0x7fba9f3c4a10
0x7fba9b05b8c0
