[英]string (to binary) to int in python?
I want to make an int from a string in python. 我想从python中的字符串做一个整数。 I thought to translate the string first to binary like this:
我想先将字符串转换为二进制,如下所示:
st = 'string'
binSt = ' '.join(format(ord(x), '08b') for x in st)
returns this: 返回此:
01110011 01110100 01110010 01101001 01101110 01100111
And then I want to translate the binary( in groups of 8) to integers which should to return this: 然后我想将binary(以8为一组)转换为整数,该整数应返回此值:
115 116 114 105 110 103
How can I do this? 我怎样才能做到这一点? Is there maybe a special function in python or something?
python中是否可能有特殊功能?
You can simply do 你可以简单地做
r = [int(numbs, 2) for numbs in binSt.split(' ')]
int(str, baseNumber)
will read the string str
and convert it to int
using baseNumber
int(str, baseNumber)
将读取字符串str
并使用baseNumber
将其转换为int
so int("0xFF", 16) = 255
and int("11", 2) = 3
所以
int("0xFF", 16) = 255
和int("11", 2) = 3
Using the solution for binary to int here: Convert base-2 binary number string to int 在此处使用将二进制数转换为int的解决方案: 将以2为底的二进制数字符串转换为int
binSt = ' '.join([str(int(format(ord(x), '08b'), 2)) for x in st])
And if you just want an array of ints 如果您只想要一个整数数组
int_array = [int(format(ord(x), '08b'), 2) for x in st]
Addressing SpoonMeiser comments. 解决SpoonMeiser的评论。 you can avoid intermediate conversions with ord(x)
您可以避免使用ord(x)进行中间转换
int_array = [ord(x) for x in st]
String to binary and then to decimal : 字符串到二进制然后到十进制:
st = 'string'
binSt = ' '.join(format(ord(x), '08b') for x in st)
binSt
##'01110011 01110100 01110010 01101001 01101110 01100111'
bin=binSt.split()
bin
##['01110011', '01110100', '01110010', '01101001', '01101110', '01100111']
print(map(lambda x: int(x,2), bin))
##[115, 116, 114, 105, 110, 103]
