Python 将dict结构从值更改为键

假设我有以下词典：

my_dict = {'month': [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12], 'year': [2006, 2012, 2003, 2006, 2012, 2018, 2020, 2011, 2000, 2001, 2013, 2013]}

我怎样才能创建一个像这样的新词典

new_dict = {'1': '2006', '2': '2012', ..., '12': '2013'}

转换为字符串值：

months = [str(item) for item in my_dict['month']]
years = [str(item) for item in my_dict['year']]
dict(zip(months, years))

---

如果只是一个技术问题，OP似乎要求将字符串作为输出，而不是int

months = [str(item) for item in my_dict['month']]
years = [str(item) for item in my_dict['year']]
dict(zip(months, years))
