本博客包含多个使用Python编写的简单游戏，如猜数字、绘制图形、猜拳等，并附带了一个计算个人所得税的小程序。通过这些游戏，读者可以了解Python的基础语法及控制流程。

# 1到100 的随机数，计算机出数，人猜数字
from random import randint

is_correct = False
count = 0
index = randint(1, 100)
print(index)
while not is_correct: # while True 条件恒成立
thy_answer = int(input('请输入数字：'))
if thy_answer == index:
print('恭喜你答对啦！')
is_correct = True # break 跳出循环
elif thy_answer > index:
print('数字偏大！')
is_correct = False
else:
print('数字偏小！')
is_correct = False
if count > 7:
print('你的智商余额不足，请尽快充值！')

count += 1

#1、用turtle模块绘制更复杂的图形
import turtle as tr

"""
# 画太阳花
tr.pencolor('red')
tr.begin_fill()
tr.fillcolor('yellow')
while True:
tr.forward(300)
tr.left(170)
if abs(tr.pos()) < 1:# 画笔是否回到原点
break
tr.end_fill()
tr.hidetr()
tr.mainloop()

"""
# 画几何图形
tr.pencolor('red')
count = 1
tr.left(20)
lenght = 20
while count < 24:
if count % 6 == 0:
lenght += 10
tr.forward(lenght)
for _ in range(5):
tr.right(60)
tr.forward(lenght)
count += 1
tr.hideturtle()

tr.mainloop()

# 2、反转的猜数字（人出数，计算机猜）
from random import randint

is_correct = False
count = 0
index = int(input('请输入数字：'))
answer = 50
while not is_correct: # while True 条件恒成立

if answer == index:
print('恭喜你答对啦！ %d' % answer)
is_correct = True # break 跳出循环
elif answer > index:
print('数字偏大！ %d' % answer)
answer = randint(0,answer)
is_correct = False
else:
print('数字偏小！ %d' % answer)
answer = randint(answer, 100)
is_correct = False

#count += 1
#if count > 7:

# print('你的智商余额不足，请尽快充值！')

#3、人机猜拳（计算机产生随机数表示剪刀石头布）
# 1：剪刀 2：石头 3：布
from random import randint

p_score = 10
c_score = 10
score = 2
while True:
if p_score <= 0:
print('一号选手输了！')
break
if c_score <= 0:
print('二号选手输了！')
break
p_num = int(input('一号选手出拳：'))
c_num = randint(1, 3)
print('二号选手出拳：%d' % c_num)

if p_num == c_num:
pass
elif p_num == 1 and c_num == 2:
p_score -= score
c_score += score
elif p_num == 1 and c_num == 3:
p_score += score
c_score -= score
elif p_num == 2 and c_num == 1:
p_score += score
c_score -= score
elif p_num == 2 and c_num ==3:
p_score -= score
c_score += score
elif p_num == 3 and c_num == 1:
p_score -= score
c_score += score
elif p_num == 3 and c_num == 2:
p_score += score
c_score -= score
print('一号选手的分数：%d, 二号选手的分数：%d' % (p_score, c_score))

4、计算个人所得税
