How to Encode String Base64 on Python 3 

in  Python 2.7 I use below this 

${encode_string}=    Encode String To Bytes    ${username}:${password}    Base64

That is Robot Framework syntax and it is the same when using Python 2.7 or 3.x.

I found the situation when I run the script on Python 2.7  it is a pass but Python 3 it got the error above.

I confirm that it works on python 2.7 but not on python 3.7.
That looks like a bug, you should open on  https://github.com/robotframework/robotframework

Hello,

you can use module codecs to do this.

I have same need. Convert hexa string into string base64.

Here an example:

b64_string = codecs.encode(codecs.decode(my_string_hexa, 'hex'), 'base64').decode()

Python 3 changed string encoding a bit and under the new scheme base64 just doesn't work. There's nothing our Encode String To Bytes keyword could do about it, but it ought to be fairly easy to implement new base64 encode/decode kws utilizing this module:
