Exercise 3 - Answer

Prashant = who_are_you('Prashant', 44,'male')

print(f"Prashant doesn't look like {Prashant['age']}!?")

#A)Prashant doesn't look 44!?

The correct answer is A!

Exercise 4 - Answer

def my_colors(color, colors=[]):
    colors.append(color)
    print(color)

my_colors('red')
my_colors('blue')


#B) red
#   blue

The correct answer is B!

The function doesn’t print the list called ‘colors’ but the variable ‘color’! So the output is ‘red’ and then ‘blue’, instead of a list containing both colors :)

Exercise 5 - Answer

def rython(sentence, start=0, end=2):
    for letter in (sentence[start:end]):
        print(letter)

my_sentence = "Now go and code some Python!"

rython(my_sentence)

#A) N
#   o

The correct answer is A!

The code prints does not include the 3d character. If we wanted to include the 3d character we needed to store the value 3 instead of 2 in the argument ‘end’
