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

...

如果(像我一样)你在数据框架中有一列月份数字，我会提供这个:

df['monthName'] = df['monthNumer'].apply(lambda x: calendar.month_name[x])

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

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

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)
