I am unsure what exactly this line is trying to do, and it won't run.

blen@phxqv:~/dev-blen/chaindev> python blockchain.py File "blockchain.py", line 62 content = f'{index}{hash_of_previous_block}{transactions}{nonce}'.encode()
^ SyntaxError: invalid syntax blen@phxqv:~/dev-blen/chaindev>

Had the same error. Used Python 3.6 and it worked for me.
