这就是我要做的:

from datetime import *

months = ["Unknown",
          "January",
          "Febuary",
          "March",
          "April",
          "May",
          "June",
          "July",
          "August",
          "September",
          "October",
          "November",
          "December"]

now = (datetime.now())
year = (now.year)
month = (months[now.month])
print(month)

输出:

>>> September

(这是我写这篇文章的真实日期)

我创建了自己的函数，将数字转换为对应的月份。

def month_name (number):
    if number == 1:
        return "January"
    elif number == 2:
        return "February"
    elif number == 3:
        return "March"
    elif number == 4:
        return "April"
    elif number == 5:
        return "May"
    elif number == 6:
        return "June"
    elif number == 7:
        return "July"
    elif number == 8:
        return "August"
    elif number == 9:
        return "September"
    elif number == 10:
        return "October"
    elif number == 11:
        return "November"
    elif number == 12:
        return "December"

然后我可以调用函数。例如:

print (month_name (12))

输出:

>>> December

datetime -基本日期和时间类型- Python文档

所有strftime格式代码的列表。月份的名称，以及格式化左零填充之类的好东西。阅读整页的内容，比如“天真”参数的规则。以下是清单的简要内容:

%a  Sun, Mon, …, Sat 
%A  Sunday, Monday, …, Saturday 
%w  Weekday as number, where 0 is Sunday 
%d  Day of the month 01, 02, …, 31
%b  Jan, Feb, …, Dec
%B  January, February, …, December
%m  Month number as a zero-padded 01, 02, …, 12
%y  2 digit year zero-padded 00, 01, …, 99
%Y  4 digit Year 1970, 1988, 2001, 2013
%H  Hour (24-hour clock) zero-padded 00, 01, …, 23
%I  Hour (12-hour clock) zero-padded 01, 02, …, 12
%p  AM or PM.
%M  Minute zero-padded 00, 01, …, 59
%S  Second zero-padded 00, 01, …, 59
%f  Microsecond zero-padded 000000, 000001, …, 999999
%z  UTC offset in the form +HHMM or -HHMM   +0000, -0400, +1030
%Z  Time zone name  UTC, EST, CST
%j  Day of the year zero-padded 001, 002, …, 366
%U  Week number of the year zero padded, Days before the first Sunday are week 0
%W  Week number of the year (Monday as first day)
%c  Locale’s date and time representation. Tue Aug 16 21:30:00 1988
%x  Locale’s date representation. 08/16/1988 (en_US)
%X  Locale’s time representation. 21:30:00 
%%  literal '%' character.

如果你只需要知道给定数字(1 - 12)的月份名称，这就不太有用了，因为当前日期并不重要。

calendar.month_name[我]

or

calendar.month_abbr[我]

在这里更有用。

这里有一个例子:

import calendar

for month_idx in range(1, 13):
    print (calendar.month_name[month_idx])
    print (calendar.month_abbr[month_idx])
    print ("")

样例输出:

January
Jan

February
Feb

March
Mar

...

'01'到'Jan'

from datetime import datetime

datetime.strptime('01', "%m").strftime("%b")    

而不是导入或下载一个新的库，你可以使用我的手动功能:

将代码复制到一个新的.py文件并运行它

快速的解释:

更改your_number并输出month_from_number，您将得到月份

    your_number = 10

    def num_to_month(*args, **kwargs):

        num = kwargs.get("num", None)

        if int(num) <= 12 and int(num) > 0:

            list_of_months = {'1': 'January', '2': 'February', '3': 'March',
                              '4': 'April', '5': 'May', '6': 'June', '7': 'July',
                              '8': 'August', '9': 'September', '10': 'October',
                              '11': 'November', '12': 'December'}

            return list_of_months[num]

        else:

            print('num_to_month function error: "num=' + str(num) + '"')

    month_from_num = num_to_month(num=your_number)

    print(month_from_num)

结果将在10月份公布
