An expression is some line of code that is executed to provide some meaningful result. Expressions can come in with unary, binary or ternary operators with several operands.
Unary expressions use just a single operand. For example, -1 is a unary expression since it only uses the negative (
>>> -1 -1 >>> +1 1
There is no need to use the
+ operand, as it's implicitly mentioned.
Binary expressions include one operator and two operands.
Try doing some math on your Python interpreter.
>>> 2 ** 5 32 >>> 123 % 23 8 >>> 19//2 9 >>> 23/2 11.5
= to assign a value to a variable. To output variable, simply type the variable name into the prompt.
