Write a Python Program to swap the values of two variables.

def swap(x,y):
    x,y=y,x
    print("swaping x=",x,"and y is ",y)

    
a=int(input("Enter number 1=>"))
b=int(input("Enter number 2=>"))
ch=int(input("press 1 for without UDF and press 2 for with UDF"))
if ch==1:
    print("Swaping without UDF")
    a,b=b,a
    print("swaping a=",a,"and b is ",b)
elif ch==2:
    print("Swaping with UDF")
    swap(a,b)
else:
    print("Invalid choice")
