Install Run error for 0.17.0

[WWWPatMac]

I am getting a SyntaxError when trying to install 0.17.0 - I'm doing the manual Command Prompt install, as my antivirus will not allow me to override the download.

Here is the command prompt message:

C:\manuskript>C:\Python34\python "C:\manuskript\bin\manuskript"
Traceback (most recent call last):
  File "C:\manuskript\bin\manuskript", line 11, in <module>
    from manuskript import main
  File "C:\manuskript\bin\..\manuskript\main.py", line 256
    LOGGER.info(f'{sig} received. Quitting...')
                                             ^
SyntaxError: invalid syntax

Can someone please help?

I also get this error when trying to create the binary myself

I think you might want to install a newer Python version. Your version (Python 3.4) has reached end of life in 2019. So that might be a reason why it gets syntax errors.

@WWWPatMac Just for the record: The code in question is written using Python 3.6+ syntax.

@TheJackiMonster I recommend a Python version check in order to provide the user with first-hand information in such cases.
This is how I do it:

def main():
    #--- Check the Python version.
    major = sys.version_info.major
    minor = sys.version_info.minor
    if  major != 3 or minor < 7:
        raise Exception(
            'Wrong Python version installed: {}.{}. ' \
            'Must be 3.7 or newer.'.format(major, minor)
        )

Edit

It just occurred to me that I myself made the mistake of creating the message as an F-string. It's fixed now.
