Week 3/4: Turtle & Statements

Question 1

Turtle uses the _________ Coordinate
System?

Answer 1

Turtle uses the Cartesian Coordinate
System

Question 2

What are Relational Operators?

Answer 2

= < > ,etc.

Question 3

Week 3 review:
How to change the colors of Python’s turtle.

Answer 3

turtle.pencolor(“green”)
turtle.fillcolor(“purple”)
turtle.color(“pink”)

Question 4

Name the 4 logical operators learned this week and a brief description.

Answer 4

else=The else statement is used to execute a block of code when none of the preceding if or elif conditions are true.
if (&nested if)=code to execute if something is true.
and=testing sets of conditions
elif=short for else if. If no test has been successful yet, an elif tries something else.

Question 5

What does == and != mean?

Answer 5

== is equal
!= is not equal

Question 6

What should a code look like, with if, elif, and else?

Answer 6

If c == d
if x == y:
g = h
elif a == b
g = h
else: e = f
else:
e = f

Question 7

Comments start with # and do not execute, what else can it do?

Answer 7

Test lines of code to help deduce why a code is failing. # can also be added in the middle of a line and will not hinder the outcome.

Question 8

How to form a Decision Structure condition?

Answer 8

create a logical expression that evaluates to either “true” or “false” using comparison operators like “greater than”, “less than”, “equal to”, and logical operators like “AND”, “OR”, and “NOT”, based on the variables or values you want to check in your program.

Question 9

What is 1 test condition and 1 path of the following code?
grade = 85

if grade >= 90:
print(“Excellent”)
elif grade >= 80:
print(“Good”)
elif grade >= 70:
print(“Average”)
else:
print(“Below Average”)

Answer 9

test condition: if grade >=90
path: if grade is 90 or higher, the program prints “Excellent”

Question 10

What is a truth table?
A B A AND B A OR B
False False False False
False True False True
True False False True
True True True True

Answer 10

Table to display truth values of logical expressions based on their inputs. Shows AND & OR

Question 11

What is the order of precedence?

Answer 11

not: Evaluate not True, which results in False.
and: Evaluate False and True, which results in False.
or: Evaluate False or False, which results in False.

Question 12

How to determine an else statement is odd or even?

Answer 12

Modulo (% symbol). Example:
num = 4
if num % 2 == 0:
print(str(num) + “is an even number”)
else:
print(str(num) + “is an odd number”)

Question 13

In Java (an IDE), IF statements use what character?
Hint: Python (an IDE) uses :

Answer 13

Curvy parentheses }

Question 14

What are the steps to Data Munging/Data Wrangling?

Answer 14

1. Sorting
2. Filtration
3. Reduction
4. Access
5. Processing

Question 15

What is Data Munging/Data Wrangling? What might you do during this?

Answer 15

The process of transforming and cleaning raw data into a more usable format. Like removing/correcting errors in the data, filling in missing values, standardizing data formats, combining data from different sources, and filtering out irrelevant information. The goal is to prepare the data for analysis. Python may use the Panda library, which can include a CSV file.

Question 16

What would
.strip()
and
.lower()
do?

Answer 16

.strip()
removes whitespace

.lower()
makes everything lower-case

Question 17

What are the 3 errors?

Answer 17

Syntax error: missing character like a :

Run time error: output works, data type is wrong/missing like converting a float to an integer.

Logic errors: program is running but code isn’t working. Hardest to find.

Question 18

How would you define the variable for:

IF snow >= 5
print(“Yeah! We have a snow day!”)

Answer 18

snow = int(input(“Enter snow accumulation on ground in inches: “)

Question 19

How to say if something is between #s?

Answer 19

IF 3 <= VARIABLE <=12:

Question 20

Concatenate to say each are done with their project:
name1 = “Bob”
name2 = “Sue”

Answer 20

result = name1 + “‘s done and “ + name2 + “‘s done”
print(result)

Question 21

What will show?
my_variable = “ I Am Capitalised”
print(my_variable)
my_stripped = my_variable.strip()
print(my_stripped)
my_lower = my_variable.lower()
print(my_lower)

Answer 21

(Indent)I Am Capitalised
I Am Capitalised
i am capitalised

Question 22

What steps to take in their order.
X > 12 or X <= 5 and Y > 5 and Z < 15 or not(Z == 2)

Answer 22

parenthesis, and, simplify and, or, simplify or

Question 23

If 10 cartons are knocked down, what will the prize be and why?
If cartons > 12 then
Prize = “Teddy Bear”
End if
If cartons > 8 then
Prize = “Baseball Hat”
End if
If cartons > 6 then
Prize = “Jump Rope”
End if
If cartons > 5 then
Prize = “Candy Bar”
Else
Prize = “nothing”
End if

Answer 23

Candy Bar because there are IF statements. If they were ELSE, it would be Baseball Hat.
