[Python知识库]Python模拟加载程序 for循环与函数的建立及调用

假设周六日休息，进步值为-0.01，那你需要每天努力多少才能赶上每天努力0.01的人？

# -- coding: utf-8 --
import time

#课上练习
scale = 10
print ("start")
for i in range(scale+1):
    a = '*' * i
    b = '.'*(scale-i)
    c = (i/scale)*100
    print("{:^3.0f}%[{}->{}]".format(c,a,b))
    time.sleep(0.1)
print("end")

def dayUp(df):
    dayup=1
    for i in range(365):
        if i%7 in [6,0]:
            dayup*=(1-0.01)
        else:
            dayup*=(1+df)
    return dayup

dayfactor=0.01
while dayUp(dayfactor)<37.78:
    dayfactor+=0.001
print("你只需要每天努力:{:.3f}".format(dayfactor))

答案是 0.019
