In this article, we are going to create an AGE Calculator that will show your age in years, months, and days with the help of the current date. We will use the PyWebIO module for creating a simple and interactive interface on the web. This is a python module mostly used to create simple and interactive interfaces on the web using Python programming. It can be installed using the below command:
pip install pywebio
Stepwise Implementation:
Step 1: Import all the required modules.
Python3
# Import the following modules from dateutil.relativedelta import relativedelta from datetime import datetime from time import strptime from pywebio.input import *from pywebio.output import *from pywebio.session import *import time |
Step 2: Getting current time and taking input from the user.
Python3
# Getting Current time. date = datetime.now().strftime("%d/%m/%Y") # Taking age from the user DOB = input("", placeholder = "Your Birth Date(dd/mm/yyyy)") |
Step 3: Checking whether the format of age is correct or not.
Python3
try: # Check whether the input age format # is same as given format val = strptime(DOB, "%d/%m/%Y") except: # If format is different, then through # an error. put_error("Alert! This is not the right format") time.sleep(3) # sleep for 3 seconds continue |
Step 4: Split the Birth Date of the user and the Current Date by ‘/’. And then Typecast all the split parts into the integer. Swap months and years for both the user’s birth date and current date.
Python3
# Split the age by '/' in_date = DOB.split('/') # split the todays date by '/' date = date.split('/') # Typecast all the converted part # into the int. in_date = [int(i) for i in in_date] date = [int(i) for i in date] newdate = [] # Swap days with years in_date[0], in_date[2] = in_date[2], in_date[0] # Swap days with years date[0], date[2] = date[2], date[0] |
Step 5: Check whether or not the current year is smaller than the User’s D.O.B year. If the current year is smaller than through an error.
Python3
if in_date <= date: now = datetime.strptime(DOB, "%d/%m/%Y") # Display output in a pop window popup("Your Age",k [put_html("<h4>"f"{relativedelta(datetime.now(),now).years} Years</br> \ {relativedelta(datetime.now(),now).months} Months</br>\ {relativedelta(datetime.now(),now).days} Days""</h4>"), put_buttons( ['Close'], onclick=lambda _: close_popup())], implicit_close=True) else: # If you input the year greater than current year put_warning( f"No result found, this is {date[0]}, and you can't be in {in_date[0]}.") |
Complete Code:
Python3
# Import the following modules from dateutil.relativedelta import relativedelta from datetime import datetime from time import strptime from pywebio.input import *from pywebio.output import *from pywebio.session import *import time # Run infinite loop while True: clear() # Put a heading Age Calculator put_html("<p align=""left""><h4> AGE CALCULATOR</h4></p> ") # Getting Current time. date = datetime.now().strftime("%d/%m/%Y") # Taking age from the user DOB = input("", placeholder="Your Birth Date(dd/mm/yyyy)") try: # Check whether the input age # format is same as given format val = strptime(DOB, "%d/%m/%Y") except: # If format is different, then through an error. put_error("Alert! This is not the right format") # sleep for 3 seconds time.sleep(3) continue in_date = DOB.split('/') date = date.split('/') # Typecast all the converted part into the int. in_date = [int(i) for i in in_date] date = [int(i) for i in date] # Define an empty list newdate = [] # Swap days with years in_date[0], in_date[2] = in_date[2], in_date[0] # Swap days with years date[0], date[2] = date[2], date[0] if in_date <= date: now = datetime.strptime(DOB, "%d/%m/%Y") # Display output popup("Your Age", [put_html("<h4>"f"{relativedelta(datetime.now(),now).years} Years</br> \ {relativedelta(datetime.now(),now).months} Months</br>\ {relativedelta(datetime.now(),now).days} Days""</h4>"), put_buttons( ['Close'], onclick=lambda _: close_popup())], implicit_close=True) else: # If you input the year greater than current year put_warning( f"No result found, this is {date[0]}, and you can't be in {in_date[0]}.") time.sleep(3) clear() # Give user a choice choice = radio("Do you want to calculate again?", options=['Yes', 'No'], required=True) if choice.lower() == 'yes': continue else: clear() # Show a toast notification toast("Thanks a lot!") exit() |
