Question

     charkey = input('\nWhat is the eight character key that was used in encryption?\n')
    for i in charkey:
      c = (ord(i))
      print('Asc2num',c) 

    Output: 
     What is the eight character key that was used in encryption?
    (*&^%$
    Asc2num 40
    Asc2num 42
    Asc2num 38
    Asc2num 94
    Asc2num 37
    Asc2num 36

我现在需要将这些数字加在一起，我已经尝试了总和（c），但它不起作用。

Answer 1

尝试使用额外的变量

charkey = input('\nWhat is the eight character key that was used in encryption?\n')
res = 0
for i in charkey:
  c = (ord(i))
  res += c

print(res)

也是较短的版本：

print(sum((ord(x) for x in charkey)))

Answer 2

sum（）将列表或任何可迭代对象作为参数。

<强>演示：

例外：

In [105]: sum(1)
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-105-5771d20eddf7> in <module>()
----> 1 sum(1)

TypeError: 'int' object is not iterable

有效：

In [106]: sum([1,2,3,4,5])
Out[106]: 15

为添加创建变量：

<强>演示：

In [108]: add = 0

In [109]: for i in range(5):
   .....:     add = add + i
   .....:     

In [110]: add
Out[110]: 10

Answer 3

我试过你的问题。这是一个解决方案

让

 c=[]

 for i in charkey:
      c.append(ord(i))
 sum(c)


>>> charkey = raw_input('\nWhat is the eight character key that was used in encryption?\n')

What is the eight character key that was used in encryption?
!@#$%^&*
>>> c
[33, 64, 35, 36, 37, 94, 38, 42]
>>> sum(c)
379

如何添加for循环下的数字？
