Python：将日期格式 YYYY-mm-dd 转换为带有缩写月份的 dd-MON-yyyy

Question

I have a date that is a string in this format:我有一个日期是这种格式的字符串：

'2021-01-16'

And need to convert it to a string in this format:并且需要将其转换为这种格式的字符串：

'16-JAN-2021'

I am able to get most of it like this:我能够像这样获得大部分内容：

x = datetime.strptime('2021-01-16', '%Y-%m-%d')
x.strftime('%d-%b-%Y')

But the month is not fully capitalized:但是月份没有完全大写：

'16-Jan-2021'

Answer 1

Just use upper() to capitalize the output string:只需使用upper()将 output 字符串大写：

from datetime import datetime

x = datetime.strptime('2021-01-16', '%Y-%m-%d')

print(x.strftime('%d-%b-%Y').upper())
# 16-JAN-2021

Answer 2

You were almost there.你快到了。 Simply use upper().只需使用upper()。

>>> from datetime import datetime
>>> datetime.strptime('2021-01-16', '%Y-%m-%d').strftime('%d-%b-%Y').upper()
'16-JAN-2021'

Answer 3

x.strftime('%d-%b-%Y').upper()

Answer 4

I read answers with upper() function, here is another way using %^b我用upper() function 阅读答案，这是另一种使用%^b的方法

from datetime import datetime
date = datetime.strptime('2011-01-16', '%Y-%m-%d')
formatted_date = date.strftime('%d-%^b-%Y')
print(formatted_date)
