[Python] 之旅第6天

實用練習

• 練習1- 用戶給半徑，要有程式能"算出面積"，並"比較"兩個圓的大小
• 公式- 日期相減 日期差的核心觀念/代碼
• 練習2- 給兩個日期 做請假系統，看有沒有超過 limit天數

練習1- 用戶給半徑，要有程式能"算出面積"，並"比較"兩個圓的大小
用 Flask 來與網頁互動
port=5000 指port端口設定為 5000
@app.route('/data') 指之後要去我們寫的file 要輸入以下
http://127.0.0.1:5000/data?
(ps. 在?後就可以開始輸入值囉)

• 以下的代碼能根據用戶給的半徑，有程式能"算出面積"，並"比較"兩個圓的大小

# import main Flask class and request object
 
from flask import Flask, request
 
# create the Flask app
app = Flask(__name__)
 
 
@app.route('/data')
def query_example():
    # if key doesn't exist, returns None
    pi = request.args['pi']
 
    # if key doesn't exist, returns a 400, bad request error
    c1 = request.args['c1']
    c2 = request.args['c2']
 
 
    c1_float = float(c1)
    c2_float = float(c2)
    pi_float = float(pi)
 
    multiply_c1 = c1_float*c1_float*pi_float
    multiply_c2 = c2_float*c2_float*pi_float
 
    if multiply_c1 > multiply_c2:
        bigger = "c1"
   
    elif multiply_c2 > multiply_c1:
        bigger = "c2"
 
    elif multiply_c2 == multiply_c1:
        bigger = "both"
 
 
 
    return '''
              <h1>The pi is: {}</h1>
              <h1>The c1_float  is: {}</h1>
              <h1>The c2_float  is: {}</h1>  
              <h1>The multiply_c1 is: {}</h1>
              <h1>The multiply_c2  is: {}</h1>
              <h1>The bigger one  is: {}</h1>
              '''.format(pi, c1_float,c2_float , multiply_c1, multiply_c2 ,bigger)
             
 
if __name__ == '__main__':
    # run app in debug mode on port 5000
    app.run(debug=True, port=5000)

成果會長這樣喔:

公式- 日期相減 日期差的核心觀念/代碼:

https://blog.csdn.net/Gordennizaicunzai/article/details/78926255

from datetime import date, datetime, time ,timedelta
  
valentine = date(2020, 2, 14)
today = date.today()
romanticlen = today - valentine
 
print(romanticlen)

成果會長這樣喔:

練習2- 給兩個日期 做請假系統，看有沒有超過 limit天數

• 以下是我寫的代碼

import datetime
from datetime import datetime, timedelta
from flask import Flask, request
from datetime import date,  datetime, time ,timedelta
app = Flask(__name__)
 
 
@app.route('/data')
 
def query_example():
   
    try:
        date1 = request.args['date1']
        date2 = request.args['date2']
       
       
        limit = 2
       
       
        date1_in_system = datetime.strptime( date1,  "%Y-%m-%d")
        date2_in_system = datetime.strptime( date2,  "%Y-%m-%d")
   
   
        daysremain = abs((date2_in_system - date1_in_system).days)
 
        status = 0
 
        if daysremain > limit:
            status = "失敗，請超過兩天"
 
        if daysremain <= limit:
            status = "可以請假"
 
   
    except Exception as e:
        return '''          
       
              <h1>捕捉錯誤資訊:  {}</h1>
              '''.format(date1+ str(e))
 
   
   
    return '''          
              <h1>The date1_in_system is: {}</h1>
              <h1>The date2_in_system is: {}</h1>
              <h1>The 請假: {}</h1>
             
              '''.format(date1_in_system, date2_in_system , status)
             
   
if __name__ == '__main__':
    # run app in debug mode on port 5000
    app.run(debug=True, port=5000)
