300

What will this code print?

flag = False
if not flag:
print ('Line 1 will be printed')
else:
print ('Line 2 will be printed')

Line 1 will be printed

400

What will this code print?

x = 10
y = 15

if x%3==0 and y%3==0:
print ('Line 1 will be printed')

elif x%3==0 or y%3==0:
print ('Line 2 will be printed')

else:
print ('Line 3 will be printed')

Line 2 will be printed

500

What will this code print?

x = 10
y = 15

if x>=y:
print ('Line 1 will be printed')

else:
if x<=y and y!=15:
print ('Line 2 will be printed')

else:
print ('Line 3 will be printed')

Line 3 will be printed

Back to Basics (1)

100

Which mathematical operator is used to raise a number to a power (exponent) in Python?

**

200

What character starts a comment in Python?

#

300

What data type is the variable "amount" assigned?

amount = 430.87

'float'

400

An int data type. Value is 98.

500

If x=10, which print statement will NOT produce a syntax error?

a. print ('I have' x 'pairs of shoes')
b. print('I have,' x ', pairs of shoes)
c. print ('I have', x, 'pairs of shoes')
d. none of the above!

c. print ('I have', x, 'pairs of shoes')

(you need to separate the items with commas!)

Back to Basics too!

100

What value and data type will the variable x be assigned?

x = 11/2

5.5 which is a 'float' (in Python, the / divides full division)

200

What value and data type will the variable y reference?

y = 9//2

4 which is an 'int'

(in Python, the // does integer division and throws away the decimal part)

300

What is the format (syntax) of the input function?

variable = function (question)

Example:
name = input("What is your name? ")

400

What will this print?

x = "10"
y = "5"
print (x + y)

"105"

(since they are strings, they get merged)

500

What will this print?

print( (6-3) * 2 + 7 % 2)
