Assume the days of the week are numbered 0,1,2,3,4,5,6 from Sunday to Saturday.(using python)

Question

Assume the days of the week are numbered 0,1,2,3,4,5,6 from Sunday to Saturday. Write a
function which is given the day number, and it returns the day name (a string). in python

Answer 1

This could be done a little simpler with a list:

def day_name(day_number):

return ['Sunday', 'Monday', 'Tuesday', ..., 'Saturday'][day_number]

And of course this doesn't take error handling into account.

Answer 2

The simplest way to do this is to use a dictionary.  You could also use a set of if statements, but the code would be more verbose. e.g.:

 

dayDict = {0:'Sunday', 1:'Monday', ... , 6:'Saturday'}

def dayName (dayNumber):

   global dayDict

   return dayDict[dayNumber]

 

Of course, this doesn't take error handling into consideration.  Consider how to handle an argument with a value < 0 or > 6.  You might want to print an error message, raise an exception, etc.  The "pythonic" way is usually to raise an exception in this case.
