If A

Kelly Mcclain If In python 3, you can use "one" in d.values() to test if "one" is among the values of your dictionary. in python 2, it's more efficient to use "one" in d.itervalues() instead. note that this triggers a linear scan through the values of the dictionary, short circuiting as soon as it is found, so this is a lot less efficient than checking whether a key is present. This is true; x%1 == 0 should be true for only ints (but it will also be true for floats with only a zero following decimal point). if you know it's going to be an int (eg, if this is a param to a function), then you could just check with modulo. i bet that is faster than math.floor(x) == x. on the not so bright side, this will be true if you pass a float like 1.0 or 5.0, and you will.

If A I'm trying to determine if a string is a subset of another string. for example: chars < "test" value < "es" i want to return true if "value" appears as part. To be pendantic, you should say "regular file", as most unix posix docs refer generically to all types of file system entries a simply "files", e.g., a symbolic link is a type of a file, as is a named pipe, regular file, directory, block special, character special, socket, etc. I was wondering if there is a pythonic way to check if something does not exist. here's how i do it if its true: var = 1 if var: print 'it exists' but when i check if something does not exist. I have a git repository with multiple branches. how can i know which branches are already merged into the main master branch?.

I have this sql: alter table dbo.channelplayerskins drop constraint fk channelplayerskins channels but apparently, on some other databases we use, the constraint has a different name. how do i. I'm not sure what you mean by your last paragraph. you do want to check if one string from a list of strings (the file extensions) is a substring of another string (the url). For example, if passed the following: a = [] how do i check to see if a is empty?. Here's how you check if a map contains a key. val, ok := mymap["foo"] if the key exists if ok { do something } this initializes two variables. val is the value of "foo" from the map if it exists, or a "zero value" if it doesn't (in this case the empty string). ok is a bool that will be set to true if the key existed. if you want, you can shorten this to a one liner. if val, ok := mymap.
