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.

list_ a = [1, 2, 3, 4, 5] 

print(id(a))

Output:

140234866534752 

method 2: Find and Print Address of Variable using addressof()

These functions also allow us to obtain memory addresses; ctypes is a Python foreign function library. It offers data types that are compatible with C and permits calling functions found in shared libraries or DLLs.

Syntax:addressof(c_int(object))

where object is the data variables

# import addressof, 

# c_int modules from ctypes module from ctypes import c_int, addressof   

# get memory address of variable 

var= 44print(addressof(c_int(var)))

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

# get id of list in hexadecimal representation 
a = [1, 2, 3, 4, 5] print(hex(id(a)))
