base 64 ( GNU/Linux vs python )

Question

on linux i can use the command "base64" to encode a string or "python -m base64 -e" they had the same output, but inside of python shell, when i use the base64 i had a different output.

#Linux promt

Command : echo 'HelloWorld' | base64

Output  : SGVsbG9Xb3JsZAo=

Command : echo 'HelloWorld' | python -m base64 -e

Output  : SGVsbG9Xb3JsZAo=

--== inside of python ==--

import base64

word = "HelloWorld".encode()
new_word = base64.b64encode(word)
print(word)
print(new_word)

output :

b'HelloWord'
b'SGVsbG9Xb3JsZA=='

what i can do ? And why this is happening ? Thanks all.

Solved :

Why that happens :

because the echo put " \n " on the end of string.

Umm, `word = "DaviMello".encode()`? Shouldn't that be `HelloWorld`? — Aran-Fey, Aug 02 '18 at 16:20
The command you are talking about is not part of Linux. Linux is the kernel only, therefore the most common combination of kernel and tools used by most distributions is called GNU/Linux. `base64` is from the GNU part.

You forgot that echo outputs a newline.

$ echo -n 'HelloWorld' | base64
