如果结果为小数，如何打印浮点数；如果结果没有小数，如何打印整数？

c = input("Enter the total cost of purchase: ")
bank = raw_input("Enter the bank of your credit card (DBS, OCBC, etc.): ")
dbs1 = ((c/float(100))*10)
dbs2 = c-dbs1
ocbc1 = ((c/float(100))*15)
ocbc2 = c-ocbc1
if (c > 200):
    if (bank == 'DBS'):
        print('Please pay $'+str(dbs2))
    elif (bank == 'OCBC'):
        print('Please pay $'+str(ocbc2))
    else:
        print('Please pay $'+str(c))
else:
    print('Please pay $'+str(c))
exit = raw_input("Enter to exit")

回答：

Enter the total cost of purchase: 250
Enter the bank of your credit card (DBS, OCBC, etc.): OCBC
Please pay $212.5
Enter the total cost of purchase: 250
Enter the bank of your credit card (DBS, OCBC, etc.): DBS
Please pay $225.0

您可以尝试使用简单的Python字符串格式化方法：

if int(c) == float(c):
    decimals = 0
else:
    decimals = 2 # Assumes 2 decimal places for money
print('Please pay: ${0:.{1}f}'.format(c, decimals))

如果满足以下条件，将为您提供以下输出c == 1.00：

Please pay: $1

或此输出，如果c == 20.56：

Please pay: $20.56
