Converting binary to string

Question

I need to convert: 1010100 1101000 1101001 1110011 100000 1101001 1110011 100000 1100001 100000 1110011 1110100 1110010 1101001 1101110 1100111 to string. I've converted string to binary

text2 = 'This is a string'
res = ' '.join(format(ord(i), 'b') for i in text2)
print(res)
#output:
1010100 1101000 1101001 1110011 100000 1101001 1110011 100000 1100001 100000 1110011 1110100 1110010 1101001 1101110 1100111

And now I've problem to converting it back to string, chr gives me some asian characters:

c = ' '.join(chr(int(val)) for val in res.split(' '))
print(c)
#output:
󶦴 􌳈 􌳉 􎿻 𘚠 􌳉 􎿻 𘚠 􌣡 𘚠 􎿻 􏁔 􎿺 􌳉 􌴶 􌥏

Then I try binascii but also not working:

l = res.split()
print(l)
for i in l:
 print (binascii.b2a_uu(bytes(i, 'utf-8')))
 output:
 b"',3 Q,#$P, \n"
 b"',3$P,3 P, \n"
 b"',3$P,3 P,0 \n"
 b"',3$Q,# Q,0 \n"
 b'&,3 P,# P\n'
 b"',3$P,3 P,0 \n"
 b"',3$Q,# Q,0 \n"
 b'&,3 P,# P\n'
 b"',3$P,# P,0 \n"
 b'&,3 P,# P\n'
 b"',3$Q,# Q,0 \n"
 b"',3$Q,#$P, \n"
 b"',3$Q,# Q, \n"
 b"',3$P,3 P,0 \n"
 b"',3$P,3$Q, \n"
 b"',3$P,#$Q,0 \n"

• Scott Hunter: What do you mean by "also not working"?
• Ziggy Witkowski: @ScottHunter You can see the output, it's still not 'This is a string'.

Answer 1

You need to set the base for int:

''.join(chr(int(val, 2)) for val in res.split(' '))

Output:

'This is a string'

• Ziggy Witkowski: What actually is this base "2"? I try to find more info to find out but can't find out.
