[datetime.date(2020, 6, 29), datetime.date(2020, 6, 30), datetime.date(2020, 7, 1), datetime.date(2020, 7, 2), datetime.date(2020, 7, 3), datetime.date(2020, 7, 4), datetime.date(2020, 7, 5)]
[datetime.date(2020, 7, 6), datetime.date(2020, 7, 7), datetime.date(2020, 7, 8), datetime.date(2020, 7, 9), datetime.date(2020, 7, 10), datetime.date(2020, 7, 11), datetime.date(2020, 7, 12)]
[datetime.date(2020, 7, 13), datetime.date(2020, 7, 14), datetime.date(2020, 7, 15), datetime.date(2020, 7, 16), datetime.date(2020, 7, 17), datetime.date(2020, 7, 18), datetime.date(2020, 7, 19)]
[datetime.date(2020, 7, 20), datetime.date(2020, 7, 21), datetime.date(2020, 7, 22), datetime.date(2020, 7, 23), datetime.date(2020, 7, 24), datetime.date(2020, 7, 25), datetime.date(2020, 7, 26)]
[datetime.date(2020, 7, 27), datetime.date(2020, 7, 28), datetime.date(2020, 7, 29), datetime.date(2020, 7, 30), datetime.date(2020, 7, 31), datetime.date(2020, 8, 1), datetime.date(2020, 8, 2)]

By updating the first day of the week we can get different elements of the list.

import calendar
my_cal= calendar.Calendar(firstweekday=3)
for x in my_cal.monthdatescalendar(2020,7):
	print(x)

As we are getting a list as output, we can get total number of weeks in a month and number of days in a week. We are using len() here to get number of elements.

import calendar
my_cal= calendar.Calendar(firstweekday=0)
y=my_cal.monthdatescalendar(2020,7)
print("Number of weeks",len(y))
print("Number of days in week",len(y[0]))

Output

Number of weeks 5
Number of days in week 7

As we are getting a list of date objects for each week , we can display month, year and day like this.

print("Day number of 4th element of first week: day,month,year \n",
      y[0][4].day , y[0][4].month,y[0][4].year)

Output

Day number of 4th element of first week: day,month,year 
 3 7 2020
