Python calendar module | itermonthdates() method

Calendar module allows to output calendars like program, and provides additional useful functions related to the calendar. Functions and classes defined in Calendar module use an idealized calendar, the current Gregorian calendar extended indefinitely in both directions. 
itermonthdates() method returns an iterator for the month (1–12) in the year. This iterator will return all days for the month and all days before the start of the month or after end of the month that are required to get a complete week.
 

Syntax: itermonthdates(year, month)

Parameter: 
year: year of the calendar
month: month of the calendar
