【python简单程序】杂

原文来源于菜鸟教程python3

1、判断是否闰年

import calendar
print(calendar.isleap(2000))

2、生成日历

# 引入日历模块
import calendar
 
# 输入指定年月
yy = int(input("输入年份: "))
mm = int(input("输入月份: "))
 
# 显示日历
print(calendar.month(yy,mm))

3、简易计算器

from math import *
from tkinter import *

def calc():
    text = var.get()
    result = eval(text)
    result = result / 1.0
    result = str(result)
    var.set(result)
text = ''
result = ''
root = Tk()
pi = 3.1415926535897932
root.geometry('360x48')
root.resizable(width=False,height=False)
root.title('Mini Calculator')
var = StringVar()
entry = Entry(root,textvariable=var,width=360)
button = Button(root,text='GET RESULT',command=calc)
entry.pack()
button.pack()
root.mainloop()

4、获取昨天日期

# 引入 datetime 模块

import datetime
def getYesterday(): 
    today=datetime.date.today() 
    oneday=datetime.timedelta(days=1) 
    yesterday=today-oneday  
    return yesterday
 
# 输出
print(getYesterday())
