Intro to Python

Variables & Types

100

What type of value is returned by input()

String

200

What is the value of x

x = 5

x = x + 2

7

300

Convert the string "42" into an integer

int("42")

400

What is the output?

x = 3

y = x * 2

x = 10

print(y)

6

500

How many possible values are there for a Boolean type? 

2

Conditionals

100

which is true? 

6 > 6

6 >= 5

7 < 10

8 == 9

6 >= 5

200

which phrase do you NEVER expect to see before "else"? 

- while

- if

- elif

while

300

Write a condition that checks if age is between 13 and 19 (inclusive).

if age >= 13 and age <= 19:

400

Describe the difference between if and elif

elif will only be checked if the above condition was FALSE. If will be checked every time.

500

Identify the bug:

if score = 100:

    print("Perfect!")

if score == 100:

Loops

100

Name the two types of loops in Python

While and For

200

What does this loop print? 

for i in range(3):

    print(i)

0

1

2

300

How many lines will this code output? 

for x in range(2, 8):

    print("hi")

6

400

What is wrong with this loop?

while count < 10:
    print(count)

count never goes up (infinite loop)

500

Write a loop that prints every number from 5 down to 1.

for i in range(5, 0, -1):

    print(i)

SDLC

100

What does the acronym SDLC stand for?

Software Development Life Cycle

200

Which SDLC phase focuses on how the software will work?

Design

300

What is one method teams use to gather requirements from clients?

Interviews, surveys, meetings, observation, etc.

400

What does the Deployment phase do?

Releases the software to users. Code "Goes Live"

500

Your client says, “This feature isn't what we wanted.” Which SDLC phase likely failed?

Requirements Gathering

Debug this code

100

What do we call the error that we get if we have a typo? For example, spelling it 'pirnt'

Syntax Error

200

Why does this crash?

num = "5"

print(num + 1)

Type error (trying to add the string "5" to the number 1)

300

Why won’t this print 1–5?

i = 1

while i <= 5:

    print(i)

i is never incremented. This results in an infinite loop

400

How many times does this print? 

for i in range(1, 100, -1):

print (i)

0

500
