help 如何把所有劳动节的具体日期输出

import pandas as pd
import time
dates = pd.Series(pd.date_range('1920','2021'))
lst = [time.strptime(str(d), "%Y-%m-%d %X").tm_wday for d in list(dates) if '-05-01' in str(d)]
print(lst)
weeks = ['星期日','星期一','星期二','星期三','星期四','星期五','星期六']
weekinfo = {weeks[i]:lst.count(i) for i in range(7)}
print(weekinfo)

怎么样才能输出1920-5-1 1921-5-1 1923-5-1 2021-5-1这样的效果，用什么命令

"%Y-%#m-%#d %X" 格式符中加2个#号

import datetime as dt
for i in range(2020,2030):
    t = dt.date(i, 5, 1)
    print(format(t, '%Y-%#m-%#d'))
