'''1.''' Which of the following is a correct way to name a variable and set its value to 5 in python? There may be more than one correct answer.

->'''A.''' my_var = 5

-->(:toggle hide q1a button show="Select":)
(:div id=q1a:)
-->%blue%Correct.%%  This is an acceptable variable name.
(:divend:)

->'''B.''' my var = 5

-->(:toggle hide q1b button show="Select":)
(:div id=q1b:)
-->%red%Incorrect.%%  Variable names cannot contain spaces.
(:divend:)

->'''C.''' myvar = 5

-->(:toggle hide q1c button show="Select":)
(:div id=q1c:)
-->%blue%Correct.%%  This is an acceptable variable name.
(:divend:)

->'''D.''' 5 = my_var

-->(:toggle hide q1a button show="Select":)
(:div id=q1a:)
-->%red%Incorrect.%%  The variable name should be on the left with the assigned value on the right.
(:divend:)

->'''E.''' myvar: = 5

-->(:toggle hide q1b button show="Select":)
(:div id=q1b:)
-->%red%Incorrect.%% ':' Has a purpose in python so it can't be used in a variable name.
(:divend:)

->'''F.''' myvar! = 5

(:div id=q1c:)
-->%blue%Correct.%% '!' Has a purpose in python so it can't be used in a variable name.

'''2.''' What is wrong with this 'if' statement that will keep it from working?

print(x)
(:sourceend:)

->'''A.''' Incorrect symbol used for 'greater than'

-->(:toggle hide q1a button show="Select":)
(:div id=q1a:)
-->%red%Incorrect.%%  It is actually the correct symbol for 'greater than'.
(:divend:)

->'''B.''' Incorrect 'if' statement syntax

-->(:toggle hide q1a button show="Select":)
(:div id=q1a:)
-->%red%Incorrect.%%  You will need to use the multiplication symbol in python as well as a symbol that will make an exponent.
(:divend:)

->'''B.''' y = 5x^4 + 2x^3 + 14x^2 + 3x + 7

-->(:toggle hide q1b button show="Select":)
(:div id=q1b:)
-->%red%Incorrect.%%  You will need to use a multiplication symbol and the correct symbol for creating an exponent.
(:divend:)

-->(:toggle hide q1c button show="Select":)
(:div id=q1c:)
-->%red%Incorrect.%%  The correct symbol for making an exponent is **, not ^.
(:divend:)

->'''D.''' 5 = y = 5*x**4 + 2*x**3 + 14*x**2 + 3*x + 7

-->(:toggle hide q1a button show="Select":)
