Python实例之天天向上

需求1:每天进步1%或者每天退步1%
dayfactor = 0.01
dayup = pow(1+dayfactor,365)
daydown = pow(1-dayfactor,365)
print("向上:{:.2f},向下:{:.2f}".format(dayup,daydown))

需求2:工作日每天进步1%，休息日每天退步1%
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))

需求3:休息日退步1%，工作日要加倍努力到什么程度才能达到每天进步1%的水平。
def dayUP(df):
dayup = 1
for i in range(365):
if i % 7 in [6, 0]:
dayup = dayup * (1 - 0.01)
else:
dayup = dayup * (1 + df)
return dayup
dayfactor = 0.01
while dayUP(dayfactor) < 37.78:
dayfactor += 0.001
print("工作日的努力参数是:{:.3f}".format(dayfactor))
