[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).
