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

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

一些好的答案已经使用了日历，但是设置语言环境的效果还没有被提及。

Calendar根据当前地区设置月份名称，例如在法语中:

import locale
import calendar

locale.setlocale(locale.LC_ALL, 'fr_FR')

assert calendar.month_name[1] == 'janvier'
assert calendar.month_abbr[1] == 'jan'

如果您计划在代码中使用setlocale，请确保阅读文档中的提示和警告以及扩展编写器部分。这里显示的示例不能代表它应该如何使用。特别是这两个部分:

在某些库例程中调用setlocale()通常不是一个好主意，因为它会影响整个程序[…] 扩展模块永远不应该调用setlocale()[…]

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)

如果你只有月份号而没有datetime实例，你可以构建一个小函数来映射number和label，如下所示:

def monthname(m):
    d={1:'En',2:'Fe',3:'Mr',4:'Ab',5:'My',6:'Jn',7:'Jl',8:'Ag',9:'Se',10:'Oc',11:'No',12:'Di'}
    return d[m]

一次打印所有月份:

 import datetime

 monthint = list(range(1,13))

 for X in monthint:
     month = datetime.date(1900, X , 1).strftime('%B')
     print(month)
