1.	Write a program to illustrate “Pass by refe-rence vs value”
Answer» #!/usr/bin/python # Function definition is here def changeme(mylist): “This changes a passed list into this function” mylist.append([l,2,3,4]); print “Values inside the function: “, mylist return # Now you can call changeme function mylist=[10,20,30]; changeme(mylist); print “Values outside the function: “, mylist It produce following result: Values inside the function: [10, 20,30, [1,2,3,4]] Values outside the function: [10,20, 30, [1,2,3,4]]

Answer»

#!/usr/bin/python # Function definition is here

def changeme(mylist): “This changes a passed list into this function”

mylist.append([l,2,3,4]);

print “Values inside the function: “, mylist

return # Now you can call changeme

function mylist=[10,20,30];

changeme(mylist);

print “Values outside the function: “, mylist

It produce following result:

Values inside the function: [10, 20,30, [1,2,3,4]] Values outside the function: [10,20, 30, [1,2,3,4]]
