了解到一些Python基础语句 那就反手敲一敲！！！
1，关于个税算法
基本算法：
扣除三险一金后月收入 = 工资 - 三险一金
应纳税所得额=扣除三险一金后月收入-扣除标准
个税
基本条件： 扣除标准3500元/月三险一金缴纳 的基准工资上限为7662 ；超过，就按照7662缴纳；
gongzi = int(input('请输入工资:'))
sanxian = 0
if gongzi >=7662:
sanxian= 7662*0.225
else:
snaxian=gongzi*0.225
suode = gongzi - sanxian -3500
shuilu = 0
kouchu = 0
if suode<=0:
print('loser')
else:
if suode<=1500:
shuilu = 0.03
elif suode<=4500:
shuilu =0.1
kouchu =105
elif suode <= 9000:
shuilu = 0.2
kouchu = 555
elif suode <= 35000:
shuilu = 0.25
kouchu = 1005
elif suode <= 55000:
shuilu = 0.3
kouchu = 2755
elif suode <= 80000:
shuilu = 0.35
kouchu = 5505
geshui = suode*shuilu-kouchu
print(geshui)2，数字类型操作
运用所学的if for 条件语句 简单的运用小操作 如：数字之间的加减乘除 及and or 在语句上的运用
# 字符串， 数字， 布尔，列表，字典
# 问题1 怎么判断输入一个整数为整数
num = input('请输入一个整数:')
num = int(num)
if num % 2 == 0:
print('偶数')
else:
print('奇数')
# 怎么判断一个数既是三的倍数也是4的倍数
num = int(input('请输入一个整数'))
if num %12 ==0 :
print('既是三的倍数又是四的倍数')
else:
print('不是三和四的倍数')
# 问题三怎么判断这个数是五的倍数还是六的倍数
num = int(input('请输入一个整数'))
if num %5 == 0:
if num %6 == 0:
print('既是5的倍数有事6的倍数')
else:
print('是五的倍数不是六的倍数')
else:
if num %6 ==0:
print('只是留的倍数')
else:
print('几部是五的倍数又不是六的倍数')
# and和or用于多个条件需要判断的情况下.一两个条件举例
# and: 只要一个条件为假,最终结果为假
# 条件1 真 条件2 真 结果 真
# 假 真 假
# 假 假 假
# or : 只要有一个条件为真,最终结果为真
# 真 真 真
# 真 假 真
# 假 假 假
# 框架， 工具 ，包 ，插件
#从random包中引出随机整数的方法
from random import randint
# 计算机当中的随机数也称之为 ‘伪随机数’
# 计算机找随机数是根据计算机内部的算法来找到的
number =randint(0,3)
print(number)
user_num = input('请输入你要猜的数字')
user_num = int(user_num)
computer_num = randint(0,3)
print(computer_num)
if(user_num == computer_num):
print('you win')
else:
print('you lose')
3.使用条件语句实行石头剪刀布
from random import randint
# 0石头 1剪刀 2布
randint (0,2)
user_num = input('请输入你要猜的数字')
# user_num = int(user_num)
computer_num = randint(0,2)
# print(computer_num)
if user_num.isdigit():
if 0<user_num>=2:
if user_num-computer_num==-1 or user_num-computer_num== 2:
print('you win')
elif user_num - computer_num ==0:
print('deuce')
else :
print('you lose')
else:
print('输入的数值大于有效范围')
else:
print('输入的雷荣格式错误，请输入0-2之间的数')
# 石头剪刀布
from random import randint
user_win = 0
computer_win= 0
deuce = 0
# index代表标号 value代表值
for index,value in enumerate(range(3)):
user_num = int(input('请输入数字'))
computer_num = randint(0,2)
if user_num-computer_num == -1 or user_num-computer_num == 2:
print('第{}局玩家胜'. format(index +1))
user_win +=1
elif user_num-computer_num == 0:
print('第{}局平局'.format(index +1))
deuce += 1
else:
print('第{}局电脑胜'.format(index +1))
computer_win += 1
print('-----------第{}局结束-----------'.format(index +1))
if computer_win == 2:
print('电脑胜')
break
elif user_win == 2:
print('玩家胜')
break
else:
if deuce == 1 and computer_win - user_win ==0 and index ==2:
print('平局')
elif deuce == 3:
print('平局')
elif deuce == 2 and index == 2:
if computer_win - user_win == 1:
print('电脑胜')
else:
print('玩家胜')4. For循环语句
运用for循环做一些简单的小问题
# for(int index = 0 ; index <10 ; index++)
for index in range (10):
print('woshinibaba')
print(index)
for index in range(50,100):
print(index)
for index in range(50,100,5):
print(index)
#1~100的和
sum = 0
for x in range(1,101):
sum = sum + x
print('x=%s'%x)
print(sum)
#问题2：获取1~100之间所有奇数之和与5的倍数之和的差
sum1 = 0
for x in range(1,101,2):
sum1 = sum1 + x
sum2 =0
for x in range(0,101,5):
sum2 = sum2 + x
sum3 = sum1 - sum2
print(sum3)
