14. Quiz: Strings

Quiz: Fix the Quote

The line of code in the following quiz will cause a SyntaxError, thanks to the misuse of quotation marks. First run it with Test Run to view the error message. Then resolve the problem so that the quote (from Henry Ford ) is correctly assigned to the variable ford_quote .

Start Quiz: 

# TODO: Fix this string!
ford_quote = 'Whether you think you can, or you think you can't--you're right.'

Operators and Strings

We’ve already seen that the type of objects will affect how operators work on them. What will be the output of this code? 

coconut_count = "34"
mango_count = "15"
tropical_fruit_count = coconut_count + mango_count
print(tropical_fruit_count)
SOLUTION: 3415 (and tropical_fruit_count is a string)

Quiz: Write a Server Log Message

In this programming quiz, you’re going to use what you’ve learned about strings to write a logging message for a server.

You’ll be provided with example data for a user, the time of their visit and the site they accessed. You should use the variables provided and the techniques you’ve learned to print a log message like this one (with the username, url, and timestamp replaced with values from the appropriate variables):

Yogesh accessed the site http://petshop.com/pets/reptiles/pythons at 16:20.

Use the Test Run button to see your results as you work on coding this piece by piece.

Start Quiz: 

username = "Kinari"
timestamp = "04:50"
url = "http://petshop.com/pets/mammals/cats"

# TODO: print a log message using the variables above.
# The message should have the same format as this one:
# "Yogesh accessed the site http://petshop.com/pets/reptiles/pythons at 16:20."

Quiz: len()

Use string concatenation and the len() function to find the length of a certain movie star's actual full name. Store that length in the name_length variable. Don't forget that there are spaces in between the different parts of a name!

Start Quiz: 

given_name = "William"
middle_names = "Bradley"
family_name = "Pitt"

name_length = #todo: calculate how long this name is

# Now we check to make sure that the name fits within the driving license character limit
# Nothing you need to do here
driving_license_character_limit = 28
print(name_length <= driving_license_character_limit)

len and Integers

We've just used the len function to find the length of strings. What does the len function return when we give it the integer 835 instead of a string?

SOLUTION: Error
