I am running below program at same time on two command line console, 

import time
var = 10
print("Variable is::-",id(var))
time.sleep(10)
var=var+1
print("Variable is::-",id(var))


console 1 output: 
C:\Users\My Laptop>python d:\p1.py
Variable is::- 1796725056
Variable is::- 1796725072

console 2 output:
C:\Users\My Laptop>python d:\p1.py
Variable is::- 1796725056
Variable is::- 1796725072

how can different console session share same memory location for variable

    Why can't they? They're run sequentially, not parallelly, so the memory of the first run has already been freed up for the second run to be allocated the same. – blhsing Dec 15 '18 at 03:33

    @blhsing OP explicitly said "run in parallel" - also it does not really have any impact on per-process address space. Some reading about [virtual memory](https://stackoverflow.com/questions/510544/virtual-memory) may help OP to figure out what they have concerns about. – Alexei Levenkov Dec 15 '18 at 03:48
  • @blhsing Even though they are running sequentially, first program is still running(due to sleep) when second one is started. So how come they share same memory space. – patilsanketv Dec 22 '18 at 04:25
