货币税和小费浮动并发症

Question

我正在制定一个程序，以查找已征税的金额并将其与小费结合在一起。我正在研究小费和介绍。代码：print "Welcome \nEnter The Amount Of Money For the Transaction"amount = raw_inputprint "Taxed Amount Below\n"taxed = (amount * float((1.065)))print taxed这就是我得到的：>>> runfile('/home/meyer/.spyder2/temp.py', wdir='/home/meyer/.spyder2')Welcome Enter The Amount Of Money For the TransactionTaxed Amount BelowTraceback (most recent call last):  File "<stdin>", line 1, in <module>  File "/usr/lib/python2.7/dist-packages/spyderlib/widgets/externalshell/sitecustomize.py", line 699, in runfile    execfile(filename, namespace)  File "/usr/lib/python2.7/dist-packages/spyderlib/widgets/externalshell/sitecustomize.py", line 81, in execfile    builtins.execfile(filename, *where)  File "/home/meyer/.spyder2/temp.py", line 8, in <module>    taxed = (amount * float((1.065)))TypeError: unsupported operand type(s) for *: 'builtin_function_or_method' and 'float'>>> 我知道我不能乘以这个浮点数，但是我找不到其他方法。甚至MPMath我正在使用python 2.7

您的代码无法正常运行，因为您需要在之后添加参数raw_input，请尝试以下操作：

print "Welcome \nEnter The Amount Of Money For the Transaction"

amount = float(raw_input())

print "Taxed Amount Below\n"

taxed = (amount * float((1.065)))

print taxed
