Monthly Day and Saturday Count
This Python script calculates and displays the number of days and Saturdays for each month of a specified year. It utilizes the 'calendar' module to efficiently determine month ranges and weekly day occurrences.
Python
# main.py
import calendar
def display_month_info(year):
"""
Displays information for each month of a given year, including the total number of days
and the count of Saturdays in that month.
Args:
year (int): The year for which to display month information.
"""
print(f'\nMonth Information for Year: {year}')
print('-------------------------------------')
# Loop through each month from January (1) to December (12)
for month_num in range(1, 13):
# Get the name of the month using calendar.month_name
month_name = calendar.month_name[month_num]
# calendar.monthrange returns a tuple: (weekday of first day, number of days)
# We are interested in the number of days in the month (index 1)
num_days_in_month = calendar.monthrange(year, month_num)[1]
saturday_count = 0
# calendar.monthcalendar returns a list of weeks, where each week is a list of 7 day numbers.
# 0 represents a day not in the month. Days of the week are Monday(0) to Sunday(6).
# Saturday is at index 5 of the week list.
month_calendar_matrix = calendar.monthcalendar(year, month_num)
# Iterate through each week in the month's calendar
for week in month_calendar_matrix:
# Check if the 6th element (Saturday) of the week is a valid day (not 0)
if week[5] != 0:
saturday_count += 1
# Print the collected information for the current month
print(f'{month_name:<10}: Days = {num_days_in_month:2d}, Saturdays = {saturday_count:1d}')
# --- Example Usage ---
if __name__ == '__main__':
# Example 1: Display information for the current year
import datetime
current_year = datetime.datetime.now().year
display_month_info(current_year)
# Example 2: Display information for a specific year (e.g., 2024)
display_month_info(2024)
# Example 3: Display information for a past year (e.g., 2023)
display_month_info(2023)
Prompt: displaying the months of the year with number of days and saturdays
