Python & Tweepy - How to compare and change times. - python

I am trying to create a number of constraints for some other code based on twitter handle sets.
I am having issues with the following code because:
TypeError: can't compare datetime.datetime to str
It seems that even though I have changed Last_Post to a datetime object initially, when i compare it to datetime.datetime.today() it is converting to string. Yes, I have checked the to ensure that Last_post is converting properly. Im not really sure what is going on. Help?
for handle in handles:
try:
user = api.get_user(handle)
#print json.dumps(user, indent = 4)
verified = user["verified"]
name = user['name']
language = user['lang']
follower_count = user['followers_count']
try:
last_post = user['status']['created_at']
last_post = datetime.strptime(last_post, '%a %b %d %H:%M:%S +0000 %Y')
except:
last_post = "User has not posted ever"
location = user['location']
location_ch = location_check(location)
if location_ch is not "United States":
location_output.append(False)
else:
location_output.append(True)
new_sum.append(follower_count)
if language is not "en":
lang_output.append(False)
else:
lang_output.append(True)
if datetime.datetime.today() - datetime.timedelta(days=30) > last_post:
recency.append(False)
else:
recency.append(True)

I think you need to convert the twitter date to a timestamp:
import time
ts = time.strftime('%Y-%m-%d %H:%M:%S', time.strptime(tweet['created_at'],'%a %b %d %H:%M:%S +0000 %Y'))

ValueError: time data 'None' does not match format '%Y-%m-%dT%H:%M:%S.%f'

For the node 'TransactionDate' i have a logic before updating it for policy"POL000002NGJ".
The logic i am trying to implement is If existing 'TransactionDate' < than today, then add 5 days with current value and parse it to xml.
Transaction Date Format in XML : 2020-03-23T10:56:15.00
Please Note that, If i parsing the DateTime value like below, It works good But i dont want to hardcode the value... I want to Parse it as a string object to handle for any datetime in format ""%Y-%m-%dT%H:%M:%S.%f""...
# <TransactionDate>
today = datetime.now()
TransactionDate = doc.find('TransactionDate')
Date = '2020-03-24T10:56:15.00'
previous_update = datetime.strptime(Date, "%Y-%m-%dT%H:%M:%S.%f")
if previous_update < today:
today = previous_update - timedelta(days=-5)
TransactionDate = today.strftime("%Y-%m-%dT%H:%M:%S.%f")
Below code while parsing it as a DateTime Object, I have an issue.. I got struck here and referenced other answers in stackoverflow and python forums, But still i got struct up here and unable to resolve the issue...
if any help to fix will be a great helpful. Thanks. Below code using lxml and getting help to support below code will helpful. Because i already completed for other nodes. My understanding is Date variable is calling as None.. But struck here to fix.. Please help..
# <TransactionDate>
today = datetime.now()
TransactionDate = doc.find('TransactionDate')
Date = str(TransactionDate)
previous_update = datetime.strptime(Date, "%Y-%m-%dT%H:%M:%S.%f")
if previous_update < today:
today = previous_update - timedelta(days=-5)
TransactionDate = today.strftime("%Y-%m-%dT%H:%M:%S.%f")
Full Code is Below
from lxml import etree
from datetime import datetime, timedelta
import random, string
doc = etree.parse(r'C:\Users\python.xml')
# <PolicyId> - Random generated policy number
Policy_Random_Choice = 'POL' + ''.join(random.choices(string.digits, k=6)) + 'NGJ'
# <TransactionDate>
today = datetime.now()
TransactionDate = doc.find('TransactionDate')
Date = str(TransactionDate)
previous_update = datetime.strptime(Date, "%Y-%m-%dT%H:%M:%S.%f")
if previous_update < today:
today = previous_update - timedelta(days=-5)
TransactionDate = today.strftime("%Y-%m-%dT%H:%M:%S.%f")
#Parsing the Variables
replacements = [Policy_Random_Choice , TransactionDate ]
targets = doc.xpath('//ROW[PolicyId="POL000002NGJ"]')
for target in targets:
target.xpath('./PolicyId')[0].text = replacements[0]
target.xpath('.//TransactionDate')[0].text = replacements[1]
print(etree.tostring(doc).decode())
Sample XML
<TABLE>
<ROW>
<PolicyId>POL000002NGJ</PolicyId>
<BusinessCoverageCode>COV00002D3X1</BusinessCoverageCode>
<TransactionDate>2020-03-23T10:56:15.00</TransactionDate>
</ROW>
<ROW>
<PolicyId>POL111111NGJ</PolicyId>
<BusinessCoverageCode>COV00002D3X4</BusinessCoverageCode>
<TransactionDate>2020-03-23T10:56:15.00</TransactionDate>
</ROW>
</TABLE>
Maybe the find method is wrong. Try this one
# <TransactionDate>
today = datetime.now()
TransactionDate = doc.xpath('//ROW/TransactionDate') # Change find to xpath
Date = str(TransactionDate[0].text) # Use the first one
previous_update = datetime.strptime(Date, "%Y-%m-%dT%H:%M:%S.%f")

Setting datetime inside QDateTimeEdit widget

I have to set the date and time available as a string in the following format.
"%Y/%m/%d %H:%M:%S"
cur_time = strftime("%H:%M:%S", gmtime())
cur_date = DATA[1]
date_time = cur_date+" "+cur_time
now = QtCore.QDate.fromString(date_time, '%Y/%m/%d %H:%M:%S')
self.dateTimeEdit.setDate(now)
But this is not working.
The format of date and datetime is different from the format of QDate and QDateTime, you should not use% in the Qt format, check the docs for more detail:
Assuming DATA[1] has a format %Y/%m/%d as you try to use, you can use the following code:
cur_time = strftime("%H:%M:%S", gmtime())
cur_date = "2018/11/10"
date_time = cur_date+" "+cur_time
now = QtCore.QDateTime.fromString(date_time, 'yyyy/M/d hh:mm:ss')
self.dateTimeEdit.setDateTime(now)

How to display different date formats in Odoo datetime fields?

Currently the date format on our Odoo CRM looks like 11/20/2017 13:03:41 but I want to display the format to July 3rd 3:00PM and on another place show as 3 Jul 3:00PM
We show this field in the form
<field name="pickup_time"/>
I have searched a lot to find how to change the format, but It's mainly to change in the local settings and it's permanently one setting for everywhere. Which would not solve of what we want, like having two different format for different places.
Along Odoo the default constant date format used is DEFAULT_SERVER_DATETIME_FORMAT. This is defined in the file misc.py
DEFAULT_SERVER_DATE_FORMAT = "%Y-%m-%d"
DEFAULT_SERVER_TIME_FORMAT = "%H:%M:%S"
DEFAULT_SERVER_DATETIME_FORMAT = "%s %s" % (
DEFAULT_SERVER_DATE_FORMAT,
DEFAULT_SERVER_TIME_FORMAT)
So if you declare the field like the following code then that constant is going to be used:
pickup_time = fields.Datetime(
string="Pickup time",
)
So if you want to use another format you can create a computed field with that custom format. You need to use some date functions: strftime (object to string) and strptime (string to object). The formats codes are explained almost at the bottom of this python documentation page
from datetime import datetime
from odoo.tools import DEFAULT_SERVER_DATETIME_FORMAT
[...]
pickup_time_formated = fields.Char( # it is going to be a readonly field
string='Pickup time formated',
compute='_compute_pickup_time_formated'
)
#api.multi
#api.depends('pickup_time')
def _compute_pickup_time_formated(self):
for record in self:
date = record.pickup_time
date_obj = datetime.strptime(date, DEFAULT_SERVER_DATETIME_FORMAT) # to convert it in a date object
v = date_obj.day % 10 # to get the remainder of the operation
if v == 1:
ordinal_suffix = 'st'
elif v == 2:
ordinal_suffix = 'nd'
elif v == 3:
ordinal_suffix = 'rd'
else:
ordinal_suffix = 'th'
# format 'July 3rd 3:00PM'
record.pickup_time_formated = datetime.strftime(date_obj, '%B %d' + ordinal_suffix + ' %I:%M %p')
# format '3 Jul 3:00PM'
# record.pickup_time_formated = datetime.strftime(date_obj, '%d %b %I:%M %p'),
And then you can show the new fields in the xml form:
<field name="pickup_time_formated"/>

My date in being transformed to UTC?

I got this function below which helps me to change a date format from one to another:
def change_time_format(self, date_string, input_format, output_format):
if date_string == None:
return None
try:
date = datetime.datetime.strptime(date_string, input_format)
timestamp = calendar.timegm(date.timetuple())
new_formatted_date = datetime.datetime.fromtimestamp(timestamp).strftime(output_format)
return new_formatted_date
except Exception as E:
print E
return None
And when i'm calling it like this:
dtu.change_time_format('2017-01-01 12:34:56', '%Y-%m-%d %H:%M:%S', '%d%m%Y %H%M%S')
I'm getting the input as:'01012017 153456' which is wrong and needs to be: '01012017 123456', there is a difference of 3 hours for some reason.
I can't find how to fix it, I searched for several ways over the web and I couldn't find nothing.
From here:
return datetime.datetime.strptime(date_string, input_format).strftime(output_format)

Parsing a date that can be in several formats in python

I would like to parse a date that can come in several formats, that I know beforehand. If I could not parse, I return nil. In ruby, I do like this:
DATE_FORMATS = ['%m/%d/%Y %I:%M:%S %p', '%Y/%m/%d %H:%M:%S', '%d/%m/%Y %H:%M', '%m/%d/%Y', '%Y/%m/%d']
def parse_or_nil(date_str)
parsed_date = nil
DATE_FORMATS.each do |f|
parsed_date ||= DateTime.strptime(date_str, f) rescue nil
end
parsed_date
end
This is concise and works. How can I do the same thing in Python?
I would just try dateutil. It can recognize most of the formats:
from dateutil import parser
parser.parse(string)
if you end up using datetime.strptime as suggested #RocketDonkey:
from datetime import datetime
def func(s,flist):
for f in flist:
try:
return datetime.strptime(s,f)
except ValueError:
pass
You can use try/except to catch the ValueError that would occur when trying to use a non-matching format. As #Bakuriu mentions, you can stop the iteration when you find a match to avoid the unnecessary parsing, and then define your behavior when my_date doesn't get defined because not matching formats are found:
You can use try/except to catch the ValueError that would occur when trying to use a non-matching format:
from datetime import datetime
DATE_FORMATS = ['%m/%d/%Y %I:%M:%S %p', '%Y/%m/%d %H:%M:%S', '%d/%m/%Y %H:%M', '%m/%d/%Y', '%Y/%m/%d']
test_date = '2012/1/1 12:32:11'
for date_format in DATE_FORMATS:
try:
my_date = datetime.strptime(test_date, date_format)
except ValueError:
pass
else:
break
else:
my_date = None
print my_date # 2012-01-01 12:32:11
print type(my_date) # <type 'datetime.datetime'>
After your tip, RocketDonkey, and the one from Bakuriu, I could write a shorter version. Any problem with it?
def parse_or_none(date):
for date_format in DATE_FORMATS:
try:
return datetime.strptime(date, date_format)
except ValueError:
pass
return None
Modifying root's answer to handle m/d/y:
from dateutil import parser
parser.parse(string, dayfirst=False)
There's also a yearfirst option, to prefer y/m/d.
