Here I am going to explain how we can swap 3
numbers in Python.
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
c = 12
print("the
value before swaping is",a,b,c)
d = a+b+c
b = a
a = c
c = d-(a+b)
print("the
value after swaping is",a,b,c)
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)
