**
+, -, *, /
Python operators that perform mathematical operations.
Python
A modern programming language named after Monty Python
What will the statement 'for num in range(2, 9, 2)' produce
2, 4, 6, 8
int
A Python data type that holds positive and negative whole numbers
float
A Python data type which stores floating-point numbers. Floating-point numbers are stored internally in two parts: a base and an exponent. When printed in the standard format, they look like decimal numbers
block
A group of consecutive statements with the same indentation.
algorithm
A set of specific steps for solving a category of problems
Statement:
A single line of Python code.
for loops
"for x in list_name" ... applies something to every item in a list
True/False: According to the behavior of integer division, when an integer is divided by an integer, the result will be a float.
False
True/False: Python formats all floating-point numbers to two decimal places when outputting using the print statement.
False
modulus operator
%, works on integers (and integer expressions) and gives the remainder when the first number is divided by the second
for num in range(4):
0, 1, 2, 3
If value1 is 2.0 and value2 is 12, what is the output of the following command? print(value1 * value2)
24.0
After the execution of the following statement, the variable price will reference the value _____. price = int(68.549)
68
