Python datetime formatted string conversion-24 hour time issue



I have a need to convert a particular formatted string to another.


Source:
2018-08-10 9:00 PM - 9:40 PM

Target:
2018-08-10 21:00:00



I wrote the following:


def startofappt(strv):
return strv.split(' - ')[0]

def convCalDate(dts, tms):
# 2018-08-08 5:50 PM
from datetime import datetime, date, time
dt = datetime.strptime(str(dts) + ' ' + str(startofappt(tms)), "%Y-%m-%d %H:%M %p")
return str(dt)

import datetime
datetoday = datetime.date.today()
from datetime import datetime, date, time
appointments_set = appointment.objects.filter(docid=11)
for appt in appointments_set:
if appt.date > datetoday:
print("Upcoming: ", appt.date, appt.time, convCalDate(appt.date, appt.time))
else:
print("Other:",appt.date, appt.time, convCalDate(appt.date, appt.time ))



Unfortunately I'm having trouble with 24 hour time.



Output:


Upcoming: 2018-08-10 9:00 PM - 9:40 PM 2018-08-10 09:00:00
Other: 2018-08-07 9:40 PM - 10:20 PM 2018-08-07 09:40:00
Other: 2018-08-07 9:00 PM - 9:40 PM 2018-08-07 09:00:00
Upcoming: 2018-08-08 5:50 PM - 6:10 PM 2018-08-08 05:50:00
Upcoming: 2018-08-08 6:10 PM - 6:30 PM 2018-08-08 06:10:00

Make it easy for us: hard-code appointments_set as the list you expect from filter.

Can you please try reading your date time as 12-hr format date-time and while returning the date return it as


def convCalDate(dts, tms):
from datetime import datetime, date, time
dt = datetime.strptime(str(dts) + ' ' + str(startofappt(tms)), "%Y-%m-%d %I:%M %p")
return str(dt)

print convCalDate("2018-08-10", "9:00 PM - 9:40 PM") #returns 2018-08-10 21:00:00

print convCalDate("2018-08-10", "9:00 AM - 9:40 PM") #returns 2018-08-10 09:00:00



Hope it helps

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

How to determine optimal route across keyboard

Image
Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
