Multiplies values on either side of the operator

Front 7

/

(Division)

Back 7

Divides left hand operand by right hand operand

Front 8

%

(Modulus)

Back 8

Divides left hand operand by right hand operand and returns remainder

Front 9

**

(Exponent )

Back 9

Performs exponential (power) calculation on operators

Front 10

//

(Floor Division)

Back 10

The division of operands where the result is the quotient in which the digits after the decimal point are removed.

Front 11

;

(semicolon)

Back 11

A syntax that allows multiple statements on the single line given that neither statement starts a new code block.

Front 12

suites

Back 12

A group of individual statements, which make a single code block

Front 13

Front 14

%s

Back 14

Is a formatter that replaces the value inputted in a string with the variable to the right of the next % sign. This %s specifier converts the object using str()

Front 15

It prevents the print from ending with a newline.

Front 16
