如何将python datetime转换为具有可读格式date的字符串？

t = e['updated_parsed']
dt = datetime.datetime(t[0],t[1],t[2],t[3],t[4],t[5],t[6]
print dt
>>>2010-01-28 08:39:49.000003

How do I turn that into a string?:

"January 28, 2010"

The datetime class has a method strftime. The Python docs documents the different formats it accepts:

• Python 2: strftime() Behavior
• Python 3: strftime() Behavior

For this specific example, it would look something like:

my_datetime.strftime("%B %d, %Y")

Here is how you can accomplish the same using python’s general formatting function…

>>>from datetime import datetime
>>>"{:%B %d, %Y}".format(datetime.now())

The formatting characters used here are the same as those used by strftime. Don’t miss the leading : in the format specifier.

Using format() instead of strftime() in most cases can make the code more readable, easier to write and consistent with the way formatted output is generated…

>>>"{} today's date is: {:%B %d, %Y}".format("Andre", datetime.now())

Compare the above with the following strftime() alternative…

>>>"{} today's date is {}".format("Andre", datetime.now().strftime("%B %d, %Y"))

Moreover, the following is not going to work…

>>>datetime.now().strftime("%s %B %d, %Y" % "Andre")
Traceback (most recent call last):
  File "<pyshell#11>", line 1, in <module>
    datetime.now().strftime("%s %B %d, %Y" % "Andre")
TypeError: not enough arguments for format string

And so on…

Using f-strings, in Python 3.6+.

from datetime import datetime

date_string = f'{datetime.now():%Y-%m-%d %H:%M:%S%z}'

very old question, i know. but with the new f-strings (starting from python 3.6) there are fresh options. so here for completeness:

from datetime import datetime

dt = datetime.now()

# str.format
strg = '{:%B %d, %Y}'.format(dt)
print(strg)  # July 22, 2017

# datetime.strftime
strg = dt.strftime('%B %d, %Y')
print(strg)  # July 22, 2017

# f-strings in python >= 3.6
strg = f'{dt:%B %d, %Y}'
print(strg)  # July 22, 2017

strftime() and strptime() Behavior explains what the format specifiers mean.

Read strfrtime from the official docs.

Python datetime object has a method attribute, which prints in readable format.

>>> a = datetime.now()
>>> a.ctime()
'Mon May 21 18:35:18 2018'
>>> 

This is for format the date?

def format_date(day, month, year):
        # {} betekent 'plaats hier stringvoorstelling van volgend argument'
        return "{}/{}/{}".format(day, month, year)
