how to solve "a bytes-like object is required, not 'str'" error

[maiya]

Hi All,

Am getting the following error, while writing a string to process using write method in python 3, and it works very well for python 2.

I have googled it and found encode() and decode. When I encode the string to utf-8 while writing, it executes without an error, however the output returns is not as expected (not as python 2 output).

This is my code snippet

process.stdin.write('exit\n')

getting the following error

File "test5.py", line 8, in <module>
process.stdin.write('exit\n'))
TypeError: a bytes-like object is required, not 'str'

Could any one please suggest/help me out to solve this issue, would be much appreciated. Thank you.

Regards,
Maiya

Hi,

What is wrong when you write

process.stdin.write('exit\n'.encode())

?

Please put the code between the pair of python tags (there's an opening one and a closing one).

You should probably be targeting python3. Is there a reason that you care about how it runs under python2?

I don't see anything in your post that shows the output or how it's different from what you want it to be when encoded.
