Operators

Info:

Operators are symbols used to perform operatios on values and the variables that hold those valuses.

Basic operators:

• Assignment Operator
  • For example when writing name = 'Garo' , in this case name is an assignment operator. If you type color = 'green' , then the color will be an assignment operator since we are assigning green as a value to it.
• Arithmetic Operator:
  • + : Sum, plus
  • - : Minus
  • • : Multiplication
  • / : Divide
  • // : A division where it rounds the answer done.
    • For example 24 / 5 would give 4.8 as a result. But if you do 24 // 5 then it will round down the result to 4. If you do it as round(24 / 5) then the result would be 5 because it rounds it up.
  • % : Gives the remainder.
    • For example if you do 32 % 5 then it would give the result of 2 as after the division operation, 2 is what remains.
  • ** : The power of.
    • For example 7 ** 2 would give you the result of 49 as the power of 2 of 7 is 49 (7 x 7).
• Boolean Operators:
  • == : Equal to. So if the result is not equal, then it will give False as output. If it is equal, than the output will be True
  • != : NOT equal.
  • > : Greater than
  • < : Less than.
  • >= : Greater than or equal.
  • <= : Less than or equal.
  • not : It is what the name suggests.
    • For example let's say that we have a variable:

      x = True
      y = False
      z = True
      
      not x
      

      And the output of the above program will be False.
  • and : This is an other boolean operator like not. But this adds two conditions. So let's take the example above.

    x and y
    

    This evaluates the first value, and then evaluates the second one ONLY if the first value is True. So the output will be False because y is False.
  • or : So on the example above, it will check if x or y is true. So if one of them is true, it is enough to have a True output.

Using operators with variables:

meaning = 42
meaning += 1

will give you this output.

43

As it means that it should do 42 + 1 and it will save that final value for the variable. So after this, if you do

meaning -= 1

Then the result will be:

42

As it will be doing 43-1 . We can use other operators like that too such as multiplication.

meaning *= 10

This means that it should multiply the value of meaning variable with 10 so the output will be:

420

And if i do:

name /= 7

Then the output will be:

60.0

Concatenate with operators:

You can use the operators to concetanate strings. For example

'Garo ' + 'Atmaca'

will output as:

Garo Atmaca
