Operators

Level: Beginner

Operators are similar to functions in Python but ever so slightly different.

Operators fall into a few different basic groups of operators.

Arithmetic:

• +. The + operator is pretty simple to understand if you know math.

• -. The - operator subtracts.

• *. Multiplication.

• **. Exponent.

• /. Divide.

• %. Percentage.

Assignment:

• <. Less than.

• >. Greater than.

• ==. Is equal.

• =. Equal.

• !=. Not equal to.

• <=. Less than or equal too.

• >=. Greater than or equal too.

Identity:

• is. Is.

• is not. Is not.

• in. Inside of list

These operators can be used in many different sectors of programming and are very important to learn.

a = 1+1 //+ operator
b = 1-1 //- operator
c = a*b //using the previous variables with the multiplication operator
d = 1**2 //1 to the power of two
e = d/d //divides variable d by itself
f = e%d //e percent of d

if e < d: //if e is less than d do something
    //some code
if e > d: //if e is more than d do something
    //some code
if e == e: //if e = e do something
    //some code
g = e //assigns the contents of e to the variable g
if e != e: //if e doesnt equal e do something
    //some code
if e <= e: //if e is less than or equal to e do something
    //some code
if e >= e: //if e is more than or equal to e do something
    //some code
if e in c: //if e as a whole is found in c do something
    //some code
if e is not in e: //if e is not in e do something
    //some code
if e is e: //if e is e do something
    //some code

If you look at the 2nd to last if statement in the code above you will notice that you can mix and match operators to make one long statement.
