How can I get the next day name in python

I tried this code but it's only giving me the current day name.

How can I get the next day name?

import datetime
d = datetime.datetime.now()

days = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday']
a = days[d.weekday()]

First add one day to your date with timedelta object, then get the name of the day with strftime('%A').

import datetime

next_day = datetime.datetime.now() + datetime.timedelta(days=1)
print(next_day.strftime('%A'))

That's it. There is no need to have extra days list and use the index (d.weekday() + 1), but if you want to do that, you should also use % operator(@Anentropic mentioned here) to prevent IndexError when your day is "Sunday". In that case .weekday() will return 6 and the days[d.weekday() + 1] will raise an exception.

We can use the modulo operator % to wraparound our lookup in the days list:

import datetime
d = datetime.datetime.now()

days = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday']

today_name = days[d.weekday()]

tomorrow_name = days[(d.weekday() + 1) % 7]

import datetime
days = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday']

Just get the next number in the array because the current day get the current:

d = datetime.datetime.now()
# Monday

a = days[d.weekday()+1]
# Tuesday

No need for a hardcoded array, use strftime()

import datetime

tomorrow = datetime.date.today() + datetime.timedelta(days=1)

print(tomorrow.strftime('%A'))
# Wednesday

Try it online!

The first step: calculate tomorrow day. Second step: get the name of tomorrow's day

import datetime
d = datetime.datetime.now()
tomorrow = d + datetime.timedelta(days=1)

days = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday']
a = days[tomorrow.weekday()]

You can add a number of days to a given date to produce a new datetime object for that date:

tomorrow = d +datetime.timedelta(days=1)
print(days[d.weekday()])

You can use strftime:

(d + datetime.timedelta(1)).strftime('%A')
>>> 'Wednesday'
