I can't figure out how to use the tk calender ui to print if the year selected is a leap year or no.
from tkinter import*
from tkcalendar import*
root=Tk()
root.title("Code project")
selectedDate = Label(root, text="")
def selectDate():
myDate =my_Cal.get_date()
selectedDate.config(text=myDate)
selectedDate.pack()
my_Cal= Calendar(root, setmode = 'day', date_pattern = 'd/m/yy')
my_Cal.pack()
openCal = Button(root, text="Select Date", command=selectDate)
openCal.pack()
root.mainloop()
this is the code i have now and it outputs this:
i want to know how to print if it is a leap year or not when the button is clicked

Just create a function that parses the myDate variable and extracts the year and then use the rules to calculate if it is a leap year.
For example:
from tkinter import*
from tkcalendar import*
root=Tk()
root.title("Code project")
selectedDate = Label(root, text="")
def selectDate():
myDate =my_Cal.get_date()
if is_leap_year(myDate): # add text to label to tell user if it's a leap year
text = myDate " It is a leap year!"
else:
text = myDate " It isn't a leap year!"
selectedDate.config(text=text)
selectedDate.pack()
def is_leap_year(date): # Check for leap year
year = int(date.split("/")[-1])
if not year % 4:
if not year % 100:
if not year % 400:
return True
return False
return True
return False
my_Cal= Calendar(root, setmode = 'day', date_pattern = 'd/m/yy')
my_Cal.pack()
openCal = Button(root, text="Select Date", command=selectDate)
openCal.pack()
root.mainloop()
CodePudding user response：
A year must fulfill the following criteria for it to be a leap year:
- The year must be evenly divisible by 4;
- If the year can also be evenly divided by 100, it is not a leap year; unless
- The year is also evenly divisible by 400. Then it is a leap year.
