【网课笔记】天天向上的力量

Q1：千分之一的力量

#DayDayUpQ1.py
dayup = pow(1.001,365)
daydown = pow(0.999,365)
print("向上：{:.2f},向下：{:.2f}".format(dayup,daydown))

结果：向上：1.44,向下：0.69

Q2：千分之五和百分之一的力量

#DayDayUpQ2.py
dayfactor = 0.005
dayup = pow(1+dayfactor,365)
daydown = pow(1-dayfactor,365)
print("向上：{:.2f},向下：{:.2f}".format(dayup,daydown))

结果：向上：6.17,向下：0.16

#DayDayUpQ2.py
dayfactor = 0.01
dayup = pow(1+dayfactor,365)
daydown = pow(1-dayfactor,365)
print("向上：{:.2f},向下：{:.2f}".format(dayup,daydown))

结果：向上：37.78,向下：0.03

在以上两个代码中使用了变量，使用变量的好处是修改一处即可

Q3：工作日的力量

#DayDayUpQ3.py
dayup = 1.0
dayfactor = 0.01
for i in range(365):
    if i%7 in [6,0]:
        dayup = dayup*(1-dayfactor)
    else:
        dayup = dayup*(1+dayfactor)
print("工作日的力量：{:.2f}".format(dayup))

结果：工作日的力量：4.63
