I am having trouble getting main() to accept dateNumber in the line following
(if year >= 1900 and year <=2099) Python is saying that dateNumber is not defined. I tried making dateNumber global at the beginning of the program and that worked (albeit with a warning from Python), but I know that's the sloppy way to get this program working.
Any help is very much appreciated.
You need to instantiate dateNumber.
if year >= 1900 and year <= 2099:
dateNumber = dateCalculationNorm(year) # Instantiate here.
if dateNumber > 31:
date = "April " + str(dateNumber - 31)
dateOutput(year, date)
else:
date = "March " + str(dateNumber)
dateOutput(year, date)
As it stands, there's nothing like that inside your main() function. There's no need to set it to a global either.

i'm working on making a program in python that uses arrays since it's the new chapter i'm learning. The goal of my program will ask the user for month day and day and I seem to have it almost done except that i have an issue with 2 lines in this whole code. I will write a comment in where i'm getting the errors.

I've tried renaming them but have gotten more errors after switching them from uppercase to lowercase and also adding snake cases.
This is my first question here so please forgive and educate on any formatting errors. I am new to Python and going through automate the boring stuff. Decided to expand the date detection project by using the clipboard and formatting some things also. The problem I have is in any operation taken on the year part of the REGEX.
I have commented out my last attempt to validate the year and gave up and changed the REGEX to only find dates from 1000 to 2999 and skipped code validation of the dates.
I now need to validate leap years but I'm back to having to work with the year variable, but once again no operation has any effect.
Basically the problem is I can extract the year value and display it but I cannot modify it or do checks against it.

In my approach to this project, I considered validating the days, months, and year ranges as part of the regular expression. I then defined functions to check for the leap year, and validate the number of days according to the months.
I found that way simpler and easier to understand and follow. As below:
dateRegex = re.compile(r'([0-3][0-9])/([0-1][0-9])/([1-2][0-9]{3})')
def is_leap_year(year):
year = int(year)
if year % 4 == 0:
if year % 100 == 0:
return year % 400 == 0
else:
return True
else:
return False
def is_valid_date(day, month, year):
if month == '02':
if is_leap_year(year):
return int(day) <= 29
else:
return int(day) <= 28
elif month in ['04', '06', '09', '11']:
return int(day) <= 30
else:
return int(day) <= 31
You can find the rest of my code below.

The problem was the operations before the year operations. The day and month operations were overwriting the year values. Not entirely sure how or why at this point, but moving the year code above the day and month code has started to fix the issue.

In python, I want a function to run at the same time as my normal script. I searched the internet and found threading, however, when I implement it and run the code, the error NameError: name 'datelabelstringvar' is not defined appears. I don't know what is wrong but when I remove threading and assign the function to a button (which I don't want just to be clear, I want it to be automatic), it works fine.

Your code makes several references to a datelabelstringvar variable. However, you never define it. That's what Python is saying.
EDIT:
It doesn't appear that you ever call the calendar function where the variable is defined.
I am trying to program a calendar that checks how many days from now/ ago (past and present) from raw_input. I need a loop that counts the days through the current year and adds it to a variable called: Total_days and this loop has to go through each year until it hits the current date that the code ran on. The end result is that the output gives you the date you entered in a complete sentence: eg. "10/08/1700 was ___ days ago" Basically my teacher explained that the past days has to add up until it hits that certain date using a loop(loops are required. This is an assignment, i cant use any other functions like delta, but loops and datetime stuff is good!) and then for the future it has to say how many days from now until that futuristic date happens using loops. I am very stumped and i need your guys' help.
Heres what i got so far:
import datetime
input_date = raw_input("Enter in full format (mm/dd/yyyy):")
year = input_date[6:10]
yeara = int(year)
montha = int(input_date[1:2])
daya = int(input_date[4:5])
from datetime import datetime
from datetime import date
now = datetime.now()
year = now.year
month = now.month
day = now.day
def isleapYear(year):
if year % 4 == 0:
check = True
if year % 100 == 0:
check = False
if year % 400 == 0:
check = True
total_days = 0
n = 12
moNum = [0,31,28,31,30,31,30,31,31,30,31,30,31]
while n > montha:
if yeara > year:
if year == isleapYear(year):
total_days += 366
elif year != isleapYear(year):
total_days += 365
if montha == month:
break
total_days += int(moNum[n])
if n == 02:
if isleapYear(year) == True:
total_days += 1
n -= 1
ny = 365
h = total_days
if yeara > year:
if year == isleapYear(year):
total_days += 366
elif year != isleapYear(year):
total_days += 365
if yeara>year:
time = "future"
if yeara<year:
time = "past"
if yeara==year:
if montha>month:
time = "future"
if montha<month:
time = past
if montha == month:
if daya>day:
time = "future"
if daya<day:
time = "past"
if daya==day:
time = "present"
print str(h.days) + " days in the " + str(time)
Thanks for helping out! i appreciate your help :)
Must you use a loop? Else, you can build from the following:
refdatestr = "2010/08/23"
refdate = datetime.strptime(refdatestr, "%Y/%m/%d")
now = datetime.now()
difference_days = (now-refdate).days
difference_days is a datetime.timedelta object. If refdate (or refdatestr) was in the future, this would be negative.
Here is an updated code, with everything fixed:
import datetime
input_date = raw_input("Enter in full format (mm/dd/yyyy):")
year = input_date[6:10]
yeara = int(year)
montha = int(input_date[1:2])
daya = int(input_date[4:5])
from datetime import datetime
from datetime import date
now = datetime.now()
year = now.year
month = now.month
day = now.day
def isleapYear(year):
if year % 4 == 0:
check = True
if year % 100 == 0:
check = False
if year % 400 == 0:
check = True
end_date = input_date
start_date = now
delta = date(year,month,day)
delta2 = date(yeara,montha,daya)
h = delta-delta2
if yeara>year:
time = "future"
if yeara<year:
time = "past"
if yeara==year:
if montha>month:
time = "future"
if montha<month:
time = past
if montha == month:
if daya>day:
time = "future"
if daya<day:
time = "past"
if daya==day:
time = "present"
print str(h.days) + " in the " + str(time)
The most important thing that you forgot is that there are functions in datetime that will automatically find the number of days till the input...
Hope this helps!!!

When I used an online python interpreter to run it, the functions worked fine. I just don't know how to run it from the command line and send the output back to the command window. Thanks
In python a file is parsed line by line from top to bottom, so the functions month,year,hour,minute and second are not defined yet for this line:
sys.stdout.write (month(hex) + " " + day(hex) + ", " + year(hex) + " " + hour(hex) + ":" + minute(hex) + ":" + second(hex))
Move these function definitions above this line.
And using a local variable with same name as the function name is not a good idea.
As sys.argv returns a list (with first element being the filename), so you can't apply hex over it. Apply hex on the items of the list, i.e hex( int(sys.argv[1]) )
>>> lis = ['foo.py', '12']
>>> hex( int(lis[1]) ) #use `int()` as hex expects a number
'0xc'
Put the line sys.stdout.write... after your function definitions.
Please, don't use month for both your function and a variable inside this function.
