python - nested loop math issue python

Question

Maybe I'm not seeing what the problem is because I've been thinking of the question all day long and I've already gotten help (but thought I could get the other part of this myself.) I'm trying to get

Day      Salary     Total Pay
______________________________
1         .01         .01
2         .02         .03
3         .04         .07
4         .08         .15
5         .16         .31
etc

but I'm having a hard time with the total pay part of the math.

for days in range(1, days + 1):
      for days in range(1, days + 1):
          for days in range(1, days +1):
              salary = .01*2**(days-1)
              total_pay = salary*.01*2**(days-1)    

This is what I have so far, but I can't for the life of me get the math to sort out. I can get close with what I have, but not what I need. Everything else works, but that total pay. would greatly appreciate any help with such a simple problem.

Answer 1

一个简单的递归解决方案：

>>> def total_pay(day):
...     if day == 1:
...         return 0.01
...     return 0.01*2**(day-1)+total_pay(day-1)

>>> total_pay(2)
0.03
>>> total_pay(3)
0.07
>>> print("{0:.2f}".format(total_pay(5)))
0.31

Answer 2

total pay是前total_pay一天工资加上当天工资的总和。

total_pay = 0
for days in range(1, days + 1):
    salary = .01*2**(days-1)
    total_pay += salary
