試試這個：

for el in days: 
    print '{:.2f}'.format(el)

This documentation更詳細地描述了字符串格式。

如果您正在使用Python版本是爲這個太舊（< 2.7，我認爲），嘗試：

print '{0:.2f}'.format(el)

如果您正在使用Python版本是太老了（< 2.6 ，我認爲），嘗試：

print "%.2f"%el

它沒有工作我得到了一個錯誤 –

你使用的是什麼版本的Python？你得到了什麼錯誤？你是如何解決這個錯誤的（或者你是如何試圖解決的）？ –

另外，您可以使用currency formatting

>>> import locale 
>>> locale.setlocale(locale.LC_ALL, '') 
'English_United States.1252' 
>>> locale.currency(188518982.18) 
'$188518982.18' 
>>> locale.currency(188518982.18, grouping=True) 
'$188,518,982.18'

我做的是同樣的問題，更多的只是一點點簡單地通過定義浮點格式爲0.01入手：

def main(): 
    num_input = int(input('How many days do you have? ')) 
    # Accumulate the total 
    total = 0.01 
    for day_num in range(num_input): 
     if day_num == 0: 
      print("Day: ", day_num, end=' ') 
      total = total 
      print("the pennies today are:", total) 
      day_num += day_num 
     else:  
      print("Day: ", day_num + 1, end=' ') 
      total += 2 * total 
      print("the pennies today are:", total)   
main()

輸出：多少天你有？ 5
天：今天0便士是：0.01
天：2便士今天是：0.03
天：3個便士今天是：0.09
天：4個便士今天是：0.27
天：5今天的便士是：0.81

Redid這個C＃示例。只需使用Visual Studio的默認控制檯應用程序設置即可開始。

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 

namespace HW_1_Penny_Doubling 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      double total = 0.01; 
      Console.WriteLine("How many completed days will you be working?"); 
      int days = int.Parse(Console.ReadLine()); 

      if(days <= 200) 
      { 
       for(int i = 1; i <= days; i++) 
       { 
        if (days == 0) 
        { 
         Console.WriteLine("At zero days, you won't even make a penny"); 
        } 
        else 
        { 
         Console.WriteLine("Day: " + i); 
         total = total + (2 * total); // Take the total and add double that to the original amount 
         Console.WriteLine("Today's total is: " + total); 
        } 
       } 

      } 
      else 
      { 
       Console.WriteLine("The value will be too high, Try a number below 200"); 

      } 
     } 
    } 
}
