Child

Great

This block of code allows a program to decide on a course of action based on whether a certain condition is true or false?

If Block

The Python ____________ executes lines of code in a Python program by converting the code into machine language a computer understands.

Integrated Development Environment (IDLE)

With the code below. What is the output if the user enters in a numeric 5 for input? weight = 0.0 shippingCost = 0.0 weight = float(input('Enter the weight of the package: ')) if weight > 10: shippingCost = 4.75 elif weight > 6: shippingCost = 4.00 elif weight > 2: shippingCost = 3.00 else: shippingCost = 1.50 print ('Shipping charge: $', format(shippingCost, '.2f'))

Shipping charge

What is the output of the output of the following code? num1 = 5 if (num1 >= 2): print(num1) else: num2 = 8 print(num2) print(num2)

Syntax Error

Consider the following 2 sets of code: Example (a): a = 1 b = 1 if (a == 1) and (b == 1): print("Hi") Example (b): a = 1 b = 1 if (a == 1): if(b == 1): print("Hi")

The two sets of code are equivalent

What is the output of the following code: x = 3 y = 3 if x > y: z = x + y else: z = y - x

There is no output

There needs to be a semicolin at the end of each "if" clause and "else" clause

An "if" block of code does not need the "else" portion of the code to be valid syntax but, if used there can only be one "else" portion?

True

Based on the following code what Boolean value is returned from the conditional expression that follows (based on x = 5): (x > 10) or (x >= 5) and (x <= 6)

True

What is the Boolean output of the following code: str1="GAry" str2="gAil" NOT(str1 > str2)

True

A Boolean ______ variable is a variable that signals when some condition exists in a program. When this variable is set to False it signals the condition does not exist and when set to True it signals the condition does exist.

flag

After the execution of the following statement, the variable sold will reference the numeric literal value as (n) ________ data type.sold = int(256.752)

if (a==b):

Which is the correct format of an IF statement (assuming the "temp" variable has been declared and assign a value)?

if (temp < 40): print("A little cold isn't it") else: print("Nice weather we're having")

and, not and or are considered _____________?

logical operators

When an "if" statement is the true or false part of another "if statement they are?

nested if statement

In Python the following are considered __________ __________. >, >=, <, <=, == and !=

relationship operators

When using the "and" operator, if the expression on the left side of the "and" operator is false, the expression on the right side will not be checked. Because the compound expression will be false if only one of the subexpressions is false, it would waste CPU time to check the remaining expression. When using the "or" operator, if the expression on the left side of the "or" operator is true, the expression on the right side will not be checked. Again, to not waste CPU time. In our textbook this is defined as ________ evaluation.

short-circuit

Which type of programming error prevents the program from calculating correct output based on the requirements of the program?

syntax

What is the output of the following code? if ("cat" > "Cat") and ("Dog" < "dog"): print("yes") else: print("no")

yes
