如何将其转换为精确的列和行？

Question

很难转换为整齐的列和行。有人可以帮忙吗？

我一直在尝试将列和行设置为0并从那里开始工作，但我无法弄明白。 我只是不知道在哪里插入信息。

n = 5

rate = 0.05

对于范围（0,3）中的n：

principal = 10000

for n in range (0,6):

    principal <= 15000

    simple = principal *  (1 + rate * n)

    compound = principal * (1 + rate)**n

    ratea = rate * 100

    ratea = int(ratea)

    principal = int(principal)

    print((ratea),"% $",principal," $","{:.2f}".format(simple)," $","{:.2f}".format(compound))

    principal = principal + 1000

rate = rate + 0.05

Answer 1

使用string方法format。
