# Variable & Memory Address

number = 13

name = 'Hello there!'

my_list = [3,'apple',67.8]


print('-----------------')
print('Address of number in decimal: ', id(number))
print('Address of number in hexadecimal:  ', hex(id(number)))
print('-----------------')
print('Address of name in decimal: ', id(name))
print('Address of name in hexadecimal:  ', hex(id(name)))
print('-----------------')
print('Address of my_list in decimal: ', id(my_list))
print('Address of my_list in hexadecimal:  ', hex(id(my_list)))

Python Output: Addresses
