[Python的]类型错误：无法格式化字符串转换期间，所有参数 [英] [Python]TypeError: not all arguments converted during string formatting

问题描述

我有是应该计算海明code为偶校验有7位整数的程序，这里是该程序：

I have a program that's supposed to calculate Hamming Code for even parity with a 7-bit integer, here is the program:

data=list(input("Enter a 7-bit binary integer:"))

if (data[0]+data[1]+data[3]+data[4]+data[6])%2 == 0:
    data.insert(8, "0")
else:
    data.insert(8, "1")

if (data[0]+data[2]+data[3]+data[5]+data[6])%2 == 0:
    data.insert(7, "0")
else:
    data.insert(7, "1")

if (data[1]+data[2]+data[3])%2 == 0:
    data.insert(6, "0")
else:
    data.insert(6, "1")

if (data[4]+data[5]+data[6])%2 == 0:
    data.insert(3, "0")
else:
    data.insert(3, "1")

print("Your 7-bit binary integer with Hamming Code parity bits:",data)

然而，当我运行这个程序，我得到这个错误：

However, when I run this program I get this error:

Traceback (most recent call last):
  File "C:\Python34\hamcode.py", line 3, in <module>
    if (data[0]+data[1]+data[3]+data[4]+data[6])%2 == 0:
TypeError: not all arguments converted during string formatting

我不知道这意味着什么，以及如何解决它，任何答复将大大AP preciated。

I'm not sure what this means and how to fix it, any responses would be greatly appreciated.

谢谢！

推荐答案

类型数据是字符串列表，而不是一个整数列表：

The type of data is a list with strings, not a list of integers:

>>> data=list(input("Enter a 7-bit binary integer:"))
Enter a 7-bit binary integer:123456
>>> data
['1', '2', '3', '4', '5', '6']

因此​​，你试图连接字符串，并如预期你不总结数字：

As such, you're trying to concatenate strings and you're not summing numbers as expected:

if (data[0]+data[1]+data[3]+data[4]+data[6])%2 == 0:

要解决这个问题，你需要的所有字符串第一变成数字：

To fix it, you'll need to change all the strings into numbers first:

data = [int(x) for x in data]

目前，这条线在列表中添加字符串重新走到一起，以一个单一的字符串，你要使用字符串格式化该字符串（以％2 其语法字符串格式化）。操作％是当应用于数模运算符，但它在应用到字符串中的字符串格式化操作符。

At the moment this line is adding the strings in the list back together to a single string and you're trying to use string formatting on that string (with % 2 which the syntax for string formatting). The operator % is the modulo operator when applied to a number but it's the string formatting operator when applied to a string.

在换句话说，你正在做的：

In other words, you're doing:

'123456' % 2

这意味着Python中试图插入 2 成字符串 123456 在适当的位置（这ISN ŧ可能的，因为没有指定为它的地方）。

which means Python is trying to insert that 2 into the string 123456 at the appropriate place (which isn't possible because there is no place designated for it).
