Converting python time stamp to day of year

Question

How can I convert a python timestamp into day of year:

Timestamp('2015-06-01 00:00:00')

I want a number where Jan 1 is 1, Jan 2 is 2... Dec 31 is 365 (for a non-leap year)

Solution 1

You might want to take a look at the function datetime.timetuple() which returns a time.struct_time object with your desired attribute. It has a named tuple interface, so you can access the values by index or attribute name.

import datetime

date = datetime.datetime.strptime("2015-06-01 00:00:00",
                                  "%Y-%m-%d %H:%M:%S")
print date.timetuple().tm_yday
#=> 152

Solution 2

First, you can convert it to a datetime.datetime object like this:

>>> import datetime
>>> format = "%Y-%m-%d %H:%M:%S"
>>> s = "2015-06-01 00:00:00"
>>> dt = datetime.datetime.strptime(s, format)

Now you can use the methods on dt to get what you want,except that dt doesn't have the function you want directly, so you need to convert to a time tuple

>>> tt = dt.timetuple()
>>> tt.tm_yday
152
