import pip command = 'install' parameter = 'selenium' second_param = 'numpy' # You can give as many package names as needed switch = '--upgrade' pip.main([command, parameter, second_param, switch]) Only needed parameters are obligatory, so both pip.main(['freeze']) and pip.main(['freeze'...
When you use python file as module there is no need always check if package is installed but it is still useful for scripts. if __name__ == '__main__': try: import requests except ImportError: print("To use this module you need 'requests' module") t ...

To understand the filter expressions, we should start with Filter Term. This is a simple array of strings, containing at least 3 elements: Filter (Field/Join field/Formula/Summary) Operator (search.Operator) Values (string value(or array of string values), to be used as filter parameter) //...
Simple filter expression is also an array. It contains one or more filter terms, combined with operators - 'AND', 'OR', 'NOT'. (Operators are case insensitive): [ ['mainline', 'is', 'T'], 'and', ['type','anyof',['CustInvc','CustCred']], 'and', 'not', ['amount', 'equalto', '0.00'], 'or'...
Filter expressions cannot include Filter Objects. This is very important. If you decide to form your filters with Filter Expression, you use array of string arrays. The following syntax is wrong: // WRONG!!! var f1 = search.createFilter({ name: 'mainline', operator: searc...

Sending data to your Watch app from your iPhone or from your iPhone to your Watch App after triggering some event is very simple, though the code can look a little complex at first. let message = ["key":"value-to-send"] WCSession.default().sendMessage(message, replyHandler: {...
