KeyError issue - unable to find root cause

[simms7400]

So i did print(req) and it's showing an invalid email address. Meaning the value for req is not a valid email address getting passed as 'emailid'. Is there a way to code in exceptions and ignore bad email addresses so the process doesn't bomb out?

hmmm - how do I make req a dictionary? Can someone assist?

Also, how do i show what 'emailid' is?

This doesn't work:

print(req['emailid'])

Thanks!
