Complete Guide to Shodan

[snippsat]

There is some old Python 2 code in there,maybe the book is a little old and not updated.
In Python 3 must do it like this:

except shodan.APIError as e:

Updated with newer string formatting f-string.

import shodan

api = shodan.Shodan('myapikeyhere')
# Wrap the request in a try/ except block to catch errors
try:
    results = api.search('apache')
    print(f"Results found: {results['total']}")
    for result in results['matches']:
        print(f"IP: {result['ip_str']}")
        print(result['data'])
        print('')
except shodan.APIError as error:
    print(f'Error: {error}')
