The challenge
You’re re-designing a blog and the blog’s posts have the following format for showing the date and time a post was made:
Weekday Month Day, time e.g., Friday May 2, 7pm
You’re running out of screen real estate, and on some pages you want to display a shorter format, Weekday Month Day that omits the time.
Write a function, shortenToDate, that takes the Website date/time in its original string format, and returns the shortened format.
Assume shortenToDate’s input will always be a string, e.g. “Friday May 2, 7pm”. Assume shortenToDate’s output will be the shortened string, e.g., “Friday May 2”.
Test cases
Test.describe("Basic tests")
Test.assert_equals(shorten_to_date("Monday February 2, 8pm"), "Monday February 2")
Test.assert_equals(shorten_to_date("Tuesday May 29, 8pm"), "Tuesday May 29")
Test.assert_equals(shorten_to_date("Wed September 1, 3am"), "Wed September 1")
Test.assert_equals(shorten_to_date("Friday May 2, 9am"), "Friday May 2")
Test.assert_equals(shorten_to_date("Tuesday January 29, 10pm"), "Tuesday January 29")
The solution in Python
Option 1:
def shorten_to_date(long_date):
# split by the `,` and return the first section
return long_date.split(",")[0]
Option 2:
def shorten_to_date(long_date):
return long_date[:long_date.index(',')]
Option 3 (using splicing):
def shorten_to_date(long_date):
# get the location of the `,`
num = long_date.find(',')
# return the splice
return long_date[0:num]
