This question already has an answer here: Can you make multiple “if” conditions in Python? [duplicate] 6 answers So I am writing some code in python 3.1.5 that requires there be more than one condition for something to happen. Example: def example(arg1, arg2, arg3): if arg1 == 1: if arg2 == 2: if arg3 == 3: print("Example Text") The problem is that when I do this it doesn't print anything if arg2 and arg3 are equal to anything but 0. Help? SSung2710 I would use def example(arg1, arg2, arg3): if arg1 == 1 and arg2 == 2 and arg3 == 3: print("Example Text") The and operator is identical to the

Is there a way to have some of the parameters mandatory based on some condition (for example, if one of the parameters is absent or false) in a PowerShell function? My idea is to be able to call a function in two ways. A concrete example is a function that gets a list from SharePoint - I should be able to call it with relative URL of the list (one and only parameter) OR with a web URL and a list display name (two parameters, both mandatory, but only if list relative URL is not used).

I want to make a new list from another list of words; when a certain condition of the word is met. In this case I want to add all words that have the length of 9 to a new list. I have used : resultReal = [y for y in resultVital if not len(y) < 4] to remove all entries that are under the length of 4. However, I do not want to remove the entries now. I want to create a new list with the words, but keeping them in the old list. Perhaps something like this: if len(word) == 9: newlist.append() Thanks. g.d.d.c Sorry, realized you wanted length, 9, not length 9 or greater. newlist = [word for word in

I'm parsing an XML file via Element Tree in python and and writing the content to a cpp file. The content of children tags will be variant for different tags. For example first event tag has party tag as child but second event tag doesn't have. -->How can I check whether a tag exists or not before parsing? -->Children has value attribute in 1st event tag but not in second. How can I check whether an attribute exists or not before taking it's value. --> Currently my code throws an error for non existing party tag and sets a "None" attribute value for the second children tag. <main> <event>

I'm writing a booking procedure for a mock airline booking database and what I really want to do is something like this: IF EXISTS (SELECT * FROM LeadCustomer WHERE FirstName = 'John' AND Surname = 'Smith') THEN INSERT INTO LeadCustomer (Firstname, Surname, BillingAddress, email) VALUES ('John', 'Smith', '6 Brewery close, Buxton, Norfolk', cmp.testing@example.com'); But Postgres doesn't support IF statements without loading the PL/pgSQL extension. I was wondering if there was a way to do some equivalent of this or if there's just going to have to be some user interaction in this step?
