Get month name from number

Question

How can I get the month name from the month number   For instance  if I have 3  I want to return march   date tm month     How to get the string march

User · Accepted Answer

Calendar API  From that you can see that calendar month name 3  would return March  and the array index of 0 is the empty string  so there s no need to worry about zero-indexing either

This is not so helpful if you need to just know the month name for a given number  1 - 12   as the current day doesn t matter    calendar month name i    or   calendar month abbr i    are more useful here    Here is an example   import calendar  for month idx in range 1  13       print  calendar month name month idx       print  calendar month abbr month idx       print        Sample output   January Jan  February Feb  March Mar

import datetime mydate   datetime datetime now   mydate strftime   B     Returns  December  Some more info on the Python doc website     EDIT   great comment from  GiriB  You can also use  b which returns the short notation for month name   mydate strftime   b     For the example above  it would return Dec

I created my own function converting numbers to their corresponding month   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    Then I can call the function  For example   print  month name  12     Outputs    gt  gt  gt  December

Some good answers already make use of calendar but the effect of setting the locale hasn t been mentioned yet  Calendar set month names according to the current locale  for exemple in French  import locale import calendar  locale setlocale locale LC ALL   fr FR    assert calendar month name 1      janvier  assert calendar month abbr 1      jan   If you plan on using setlocale in your code  make sure to read the tips and caveats and extension writer sections from the documentation  The example shown here is not representative of how it should be used  In particular  from these two sections   It is generally a bad idea to call setlocale   in some library routine  since as a side effect it affects the entire program       Extension modules should never call setlocale
