Hi there
Im not great at python, but okay.
I have used pip to install the pywhatkit on my RPi 3B+.
When I try to import it and send a simple message, as shown at a few different examples online - I get this error. Can someone help? 
Formatted string literals were introduced in Python 3.6:
https://docs.python.org/3.6/whatsnew/3.6.html#pep-498-formatted-string-literals
Your Python is 3.5, so this is not compatible. Version 4.7 of pywhatkit is the last compatible version with 3.5, pip should have installed that.
Thanks! I will try that,
