Instructions and help about 3 Operators, Functions, Expressions, Conditions

Hi friends and welcome to geeksforgeeks, in this tutorial, we will be learning more about python. We will learn about variables, expressions, conditions and function. So, let’s just move to the GeeksforGeeks IDE to run our scripts. Variables need not be declared first in python. They can be used directly. Variables in python are case sensitive as most of the other programming languages. Let’s look at an example, here we have 2 variables “a” and “A”, “a” = 2 and “A” = 3. Let’s print both of them, so when we run the code, we get the output as 2 and 3 as expected. So, Variables need not be declared first in python. They can be used directly and they are case sensitive. Now, let’s talk about arithmetic expressions. We can perform the expressions directly, we need not do anything special for them. Suppose we first print (a + A), then we print (a*A), then we print (a/A). Now, let’s run this program. We can see that the output is as expected. Now, let’s talk about
