Pythonで特定の年月の曜日の日数を取得する方法

今回は「Pythonで特定の年月の曜日の日数を取得する方法」について紹介したいと思います。

import datetime
from calendar import monthrange
 
#年月の設定
year = 2023
month = 1
#月末日の取得(youbiにはその年月の1日の曜日が入ります)
youbi, lastDay = monthrange(int(year), int(month))
#日曜日カウント用変数
sundayCount = 0
saturdayCount = 0
fridayCount = 0
thursdayCount = 0
wednsdayCount = 0
tuesdayCount = 0
mondayCount = 0
#ループ処理
for dayNum in range(lastDay):
    #日曜日の場合、カウントアップ
    if datetime.datetime(int(year), int(month), dayNum + 1).weekday() == 6:
        sundayCount += 1
    elif datetime.datetime(int(year), int(month), dayNum + 1).weekday() == 5:
        saturdayCount += 1
    elif datetime.datetime(int(year), int(month), dayNum + 1).weekday() == 4:
        fridayCount += 1
    elif datetime.datetime(int(year), int(month), dayNum + 1).weekday() == 3:
        thursdayCount += 1
    elif datetime.datetime(int(year), int(month), dayNum + 1).weekday() == 2:
        wednsdayCount += 1
    elif datetime.datetime(int(year), int(month), dayNum + 1).weekday() == 1:
        tuesdayCount += 1
    elif datetime.datetime(int(year), int(month), dayNum + 1).weekday() == 0:
        mondayCount += 1
#日曜日の数を表示
print('日曜日',sundayCount)
print('土曜日', saturdayCount)
print('金曜日', fridayCount)
print('木曜日', thursdayCount)
print('水曜日', wednsdayCount)
print('火曜日', tuesdayCount)
print('月曜日', mondayCount)
