是什么原因造成“类型错误：不串中转换的所有参数格式”

Question

此代码产生错误：

# -*- coding: utf-8 -*- 
amount = float(input("Enter the purchase price please.")) 
down_payment=amount *0.10 
monthly_rate = (amount - down_payment) *.05 

ending_balance=amount-down_payment 

print("|Ø-6s|Ø-16s|Ø-9s|Ø-8s|Ø-14s|" % ("Month" , "Current Balance" , "Interest" , "Payment" , "Ending Balance")) 
month = 1 
while True: 
    starting_balance = ending_balance 
    interest = starting_balance * 0.01 
    final_amount = (starting_balance+interest) 

    if monthly_rate > final_amount: 
      monthly_rate = final_amount 


    ending_balance = final_amount - monthly_rate 

    print("|Ø-6f|Ø-16f|Ø-9f|Ø-8f|Ø-14f|" % (month , starting_balance , interest , monthly_rate , ending_balance)) 
    month+=1 

    if ending_balance <= 0: 
     break 

错误：

<module> 
    print("|Ø-6s|Ø-16s|Ø-9s|Ø-8s|Ø-14s|" % ("Month" , "Current Balance" , "Interest" , "Payment" , "Ending Balance")) 
TypeError: not all arguments converted during string formatting 

Answer 1

您的格式化使用%代替Ø字符串。

print("|%-6s|%-16s|%-9s|%-8s|%-14s|" % ("Month" , "Current Balance" , "Interest" , "Payment" , "Ending Balance")) 

和

print("|%-6f|%-16f|%-9f|%-8f|%-14f|" % (month , starting_balance , interest , monthly_rate , ending_balance))
