Consider two variable a & b

The core logic:
a = a + b
b = a - b
a = a - b

Program in Python:

a = int(input("Enter First Number "))
b = int(input("Enter Second Number "))

a=a+b
b=a-b
a=a-b

print("Two Numbers After Swapped => a - {} & b - {}".format(a, b))

Hi Arun, it's very simple to learn Python & it is one of the easiest & fastest languages to learn, i.e., in exactly 2 weeks you would be able to code some simple programming questions like Fibonacci, amstrong number, etc. 

Now since you have got some fundamentals, you should start your training driven towards your end goal, if you are going to program micro-controllers for IoT applications learn Python applications with Raspberry or Arduino which would take 3-4 weeks if you can afford 4-5 hours a week. 

If you are planning to apply for Software oriented roles, now you would have focused more on CS fundamentals which is Problem Solving & Algorithmic Analysis with Python, which would take around 5-6 six weeks for you to get a good hold, before given interviews.
