Python Programming: Swapping two numbers using Function
def swap(a,b):
a,b=b,a
print("After swapping","a=",a," b=",b)
a=10
b=20
print("Before swapping a=",a," and b=",b)
swap(a,b)
Python Programming: Area of Triangle
#Find the area of triangle import math a= int ( input ( "Enter the length of first side : " )) b= int ( input ( "Enter the length of second side : " )) c= int ( input ( "Enter the lenth of third side : " )) if ((a+b)>c and (c+a)>b and (b+c)>a): s=(a+b+c)/ 2 Area=math.sqrt(s*(s-a)*(s-b)*(s-c)) print ( "Area of the triangle : " , Area) else : print ( "Invalid Triangle" ) Output: Run 1: Enter the length of first side : 2 Enter the length of second side : 2 Enter the lenth of third side : 6 Invalid Triangle Run 2: Enter the length of first side : 6 Enter the length of second side : 4 Enter the lenth of third side : 7 Area of the triangle : 11.976539567003485
