Python script I want run loop when system time 30 second

I want to run the loop only when the actual system time has 30 seconds mark and then onwards every iteration happens after 1 minute.
import pandas as pd
from datetime import datetime
df = pd. read_excel('data.xlsx')
Time30 = now.replace(hour=00, minute=00, second=30)
for i in df.index:
entry = df.loc[i]
now = datetime.now()
current_time = now.strptime('%S')
current_time == Time30
name_input = browser.find_element_by_name('fullname')
password_input = browser.find_element_by_name('password")

How to put in if statement date format for entry in tkinter?

def Verification():
date_format = "%d/%m/%Y"
if (datetime.strptime("1/1/2001", date_format) <= date_ < datetime.strptime("31/1/2008", date_format)):
print('bravo')
date_= datetime.strptime(date_,date_format)
vt=date_
vt =StringVar()
vt.set('')
lb = Label(parent, text = 'birth day: ')
cp = Entry(parent, textvariable=vt)
bt = Button(parent, text ='Verify', command = Verification)
lb.place(x=30, y=90)
cp.place(x=95, y=90)
bt.place(x=220,y=90)

I'm not sure I understand your question, so the following is an answer based on what I think you're asking.
It works like this: When the Verify button is pressed the verification() function will be called which will initially attempt to parse what the user inputted into a datetime instance. If it cannot do that a error message indicating that will appear. If it succeeds then it next checks to see if it's in the required date range. Again, displaying an error message if it isn't.
from datetime import datetime
from tkinter import *
import tkinter.messagebox as messagebox
DATE_FORMAT = "%d/%m/%Y"
MIN_DATE = datetime.strptime('1/1/2001', DATE_FORMAT)
MAX_DATE = datetime.strptime('31/1/2008', DATE_FORMAT)
def verification():
try:
date_= datetime.strptime(vt.get(), DATE_FORMAT)
except ValueError:
messagebox.showerror('Invalid Date', f'"{vt.get()}"')
return
if MIN_DATE <= date_ < MAX_DATE: # Check date range.
messagebox.showinfo('Bravo', "You entered a valid date!")
else:
messagebox.showerror('Out of range', vt.get())
parent = Tk()
parent.geometry('300x200')
vt = StringVar(value='D/M/Y') # Initially show required format.
lb = Label(parent, text='birth day: ')
cp = Entry(parent, textvariable=vt)
bt = Button(parent, text ='Verify', command=verification)
lb.place(x=30, y=90)
cp.place(x=95, y=90)
bt.place(x=220,y=90)
parent.mainloop()

Index Error, countdown calendar not working

Can you help me with my code?
I wanted an if-else statement, that if there is no description for the festival is given, it displays there is no info about that particular festival. But for that, I would have to do if not(event[2]) but for that, it shows

When you evaluate event[2] it attempts to retrieve the 3rd item in the list which isn't there so python raises an exception.
One solution could be by initializing your list with default values:
event = [None for i in range(3)]
This way there is a None value at event[2] which can be evaluated by your if statement.
Another solution could be to simply check whether the list contains less than 3 items:
if len(event) <= 2:
# do something

Tkinter python index

I was making a countdown calendar that checks how many days left, name and info, but it is the condition that changes the colour for if more than 50 days part that doesn't work. Can you guys check it?. It checks how many left for each festival. Also as u can see If I change the date to today of any festival, it shows 1 Day left until. I want to fix that

There are a couple of problems with the date calculations.
Firstly you can obtain the number of days using the days attribute of the timedelta object returned by date1 - date2 in days_between_dates(). That function could be written as:
def days_between_dates(date1, date2):
return (date1 - date2).days
This is more succinct and less error prone, and now it will return an integer that is more useful in other calculations.
This also fixes a bug. When the dates are the same and str(date1 - date2) returns
'0:00:00' which your code fails to parse.
Regarding the greater than 50 condition, there is no such check in your code. There is a > 10 but your test data does not test that condition. You should add a line with a date within 10 days of the current day.
Finally you will need to handle past events for when the event has already happened. Currently the fixed code would display a negative number of days until the event.

if date is weekend - auto rerun the function

So I can generate random days in a given start-end date relationship, but, if the date happens to be a weekend - currently all I can get working is to print to the user 'it is a weekend'. What I would like to do is, if the random day IS a weekend, rerun the function so the user does not have to manually. Basically - only print out weekdays - currently, if the random day is a weekend, it prints a blank space or None value. Only return/print weekdays is the main goal.
Here is the code so far:
from datetime import datetime, timedelta
from random import randrange
def random_date(start, end):
delta = end - start
random_day = randrange(delta.days)
myresult = start + timedelta(days=random_day)
return myresult
d1 = datetime.strptime('9/1/2018', '%m/%d/%Y')
d2 = datetime.strptime('9/30/2018', '%m/%d/%Y')
myresult = random_date(d1, d2)
if myresult.weekday() not in (5, 6):
print myresult.strftime('%m-%d-%Y')
else:
print "hit a weekend"

An option:
def random_weekday(start, end):
date = None
while (not date or date.weekday() in (5, 6)):
days = randrange((end - start).days)
date = start + timedelta(days=days)
return date
start = datetime.strptime('9/1/2018', '%m/%d/%Y')
end = datetime.strptime('9/30/2018', '%m/%d/%Y')
for i in range(20):
print(random_weekday(start, end).strftime('%m-%d-%Y'))

So, you need a while-loop to keep getting dates until you get one that's not a weekend, like this:
from datetime import datetime
from random import randrange
from datetime import timedelta
def random_date(start, end):
delta = end - start
random_day = randrange(delta.days)
myresult = start + timedelta(days=random_day)
return myresult
while True:
d1 = datetime.strptime('9/1/2018', '%m/%d/%Y')
d2 = datetime.strptime('9/30/2018', '%m/%d/%Y')
myresult = random_date(d1, d2)
if myresult.weekday() not in (5,6):
break
print myresult.strftime('%m-%d-%Y')
