如何在Python创建 AGE Calculator Web App PyWebIO？

在本文中，我们将创建一个年龄计算器，它会借助当前日期以年、月和日为单位显示您的年龄。我们将使用 PyWebIO 模块在网络上创建一个简单的交互式界面。这是一个Python模块，主要用于使用Python编程在 Web 上创建简单的交互式界面。可以使用以下命令安装它：

pip install pywebio

分步实施：

第 1 步：导入所有必需的模块。

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

第 2 步：获取当前时间并接受用户的输入。

# Getting Current time.
date = datetime.now().strftime("%d/%m/%Y")  
  
# Taking age from the user
DOB = input("", placeholder = "Your Birth Date(dd/mm/yyyy)")

第三步：检查年龄格式是否正确。

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

第 4 步：将用户的出生日期和当前日期按“/”拆分。然后将所有拆分的部分 Typecast 为整数。交换用户的出生日期和当前日期的月份和年份。

# 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]

步骤5：检查当前年份是否小于用户的DOB 年份。如果当前年份小于通过错误。

if in_date <= date:
        now = datetime.strptime(DOB, "%d/%m/%Y")
      
        # Display output in a pop window
        popup("Your Age",k
              [put_html("
"f"{relativedelta(datetime.now(),now).years} Years
 \
              {relativedelta(datetime.now(),now).months} Months
\
              {relativedelta(datetime.now(),now).days} Days""
"), 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]}.")
