I'm trying to write a program that sees if two dates match out of a list of 30 dates ranging from 1 to 365
While trying to test the program, I keep encountering the error "'<=' not supported between instances of 'list' and 'int'" and I'm not sure how to proceed.



Here is my program so far:



import random



MaxInList = 30



def createDayNumberList( howMany = MaxInList ):



      dayNumbers = 

      for counter in range( howMany ):

            nextDayNumber = random.randint( 1, 365 )

            dayNumbers.append( nextDayNumber )

      return dayNumbers



def determineDate( dayNumber = 1 ):



      months = [ 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31]

      name = ["Jan", "Feb", "Mar", "Apr", "May", "Jun",

              "Jul", "Aug", "Sep", "Oct", "Nov", "Dec" ] 

      endOfMonth = 0

      daysSoFar = 0

      for month in range( len( months ) ):

            endOfMonth += months[month]

            if dayNumber <= endOfMonth:

                  date = name[month]

                  date += " " + str( dayNumber - daysSoFar )

                  return date

            daysSoFar = endOfMonth

      return "Bad date!"



def main ():



    listsToGenerate = 10

    for n in range( listsToGenerate ):

        determineDate( createDayNumberList () )

        print("")



main ()


Any sort of help/feedback is greatly appreciated!

    createDayNumberList () returns a list, which sets dayNumber to a list. Then you do dayNumber <= endOfMonth.

Issue is in your main() function:



def main ():



    listsToGenerate = 10

    for n in range( listsToGenerate ):

        determineDate( createDayNumberList() ) ## 

        print("")


createDayNumberList() returns a List object. This is passed to determineDate() and then the comparison is made:



if dayNumber <= endOfMonth ,
where dayNumber is a List object and endOfMonth is an INT. Hence, the error.



In my understanding, since your createDayNumberList() always returns just 1 value, you can store it in a variable rather than storing it in a list.



Something like:



def createDayNumberList( howMany = MaxInList ):

    dayNumbers = 

    for counter in range( howMany ):

        nextDayNumber = random.randint( 1, 365 )

        #dayNumbers.append( nextDayNumber )

      return nextDayNumber


Now, this function also returns an int. So, the comparison in determineDate() will always be correct.

Issue is in your main() function:



def main ():



    listsToGenerate = 10

    for n in range( listsToGenerate ):

        determineDate( createDayNumberList() ) ## 

        print("")


createDayNumberList() returns a List object. This is passed to determineDate() and then the comparison is made:



if dayNumber <= endOfMonth ,
where dayNumber is a List object and endOfMonth is an INT. Hence, the error.



In my understanding, since your createDayNumberList() always returns just 1 value, you can store it in a variable rather than storing it in a list.
