conditional-statements

In the python library networkx I would like to remove the nodes and edges of a graph which have some property. For example, suppose I wanted to remove all nodes and edges where the degree of a node was < 2. Consider the following psuedocode: vdict = g.degree_dict() #dictionary of nodes and their degrees g.remove_from_nodes(v in g s.t. vdict[v] < 2) I have seen some syntax that uses set theory notation but as I am still new to python I do not know how to use it. How do I convert this into working python code? The Graph.remove_nodes_from() method takes a list (container actually) of nodes. So

I have a database with a large number of words but i want to select only those records where the character length is equal to a given number (in example case 3): $query = ("SELECT * FROM $db WHERE conditions AND length = 3"); But this does not work... can someone show me the correct query? Sorry, I wasn't sure which SQL platform you're talking about: In MySQL: $query = ("SELECT * FROM $db WHERE conditions AND LENGTH(col_name) = 3"); in MSSQL $query = ("SELECT * FROM $db WHERE conditions AND LEN(col_name) = 3"); The LENGTH() (MySQL) or LEN() (MSSQL) function will return the length of a string

How do I create a new usermeta field with a drop down selection values? Im want to create a conditional statement for all users with a certain value of the new custom field I want. For example, The new field would be: Approved The drop down values are: Yes and No The conditional statement will recognize all users with the Approved field value of Yes. Then it will post a code. Im working with the wp_get_current_user function(), which does exactly what I need, but I just need a new custom usermeta field. In the example the new usermeta field would be "artwork_approved." Example: wp_get_current

a very easy question: considering an If...Then...Else instruction in VBA, how can I separate multiple instructions after Then ? In other words, should I write something like If condition [ Then ] [ statement1 ] & [statement2] Else [Else statement] (i.e. using "&"), or If condition [ Then ] [ statement1 ] And [statement2] Else [Else statement] (i.e. using "And"), or some other separator/command? Multiple statements are to be separated by a new line: If SkyIsBlue Then StartEngines Pollute ElseIf SkyIsRed Then StopAttack Vent ElseIf SkyIsYellow Then If Sunset Then Sleep ElseIf Sunrise or

I have a responsive website and I need some PHP conditions depending on the windows width (or media queries). Example: if ($window_width > 1400px) { echo 'Your window is wider than 1400px'; } elseif ($window_width > 1000px) AND ($window_width < 1399px) { echo 'Your window is between 1000px and 1399px'; } else { echo 'Your window is narrower than 1000px.'; } Thanks for your help! check this Goolgle Mobile Detect Try to use http://www.php.net/get_browser and check for isMobileDevice field. It might help only, of course, if the path to browscap.ini is set up in php.ini. If not, you can use php

A variable returns MINGW32_NT-5.1 or CYGWIN_NT-5.1. (yea, dot at the end) Need to compare that given var contains NT-5.1 positioned anywhere. Using cygwin and would like to be compatible with pretty much any *nix. The findstring function is what your heart desires: $(findstring find , in ) Searches in for an occurrence of find . If it occurs, the value is find ; otherwise, the value is empty. You can use this function in a conditional to test for the presence of a specific substring in a given string. Thus, the two examples, $(findstring a,a b c) $(findstring a,b c) produce the values "a" and
