Here I am going to explain
how we can swap 2 variable value using 3rd variable.
Step
1: Open
IDLE(Python GUI) in your system.
Step 2 : Type the below code and save the code Eg:- I have saved with swap
name.
a = 8
b = 7
print("the value for 1st variable is",a)
print("the value for 2nd variable is",b)
d = a
a = b
b = d
print("the
value after swaping 1st variable is",a)
print("the value after swaping 2nd variable is",b)
Step 3 : Open command prompt.
Step
4 : Go to the saved script folder.
Step
5 : Write python <Script name>.py for
execution.(Eg.- python swap.py)
