var array = [3, 2, 1] Creating a new sorted array As Array conforms to SequenceType, we can generate a new array of the sorted elements using a built in sort method. 2.12.2 In Swift 2, this is done with the sort() method. let sorted = array.sort() // [1, 2, 3] 3.0 As of Swift 3, it has...

py.test is one of several third party testing libraries that are available for Python. It can be installed using pip with pip install pytest The Code to Test Say we are testing an addition function in projectroot/module/code.py: # projectroot/module/code.py def add(a, b): return a + b ...

A failing test will provide helpful output as to what went wrong: # projectroot/tests/test_code.py from module import code def test_add__failing(): assert code.add(10, 11) == 33 Results: $ py.test ================================================== test session starts ===============...

Annotation types are defined with @interface. Parameters are defined similar to methods of a regular interface. @interface MyAnnotation { String param1(); boolean param2(); int[] param3(); // array parameter } Default values @interface MyAnnotation { String param1() defau...

The first argument of re.match() is the regular expression, the second is the string to match: import re pattern = r"123" string = "123zzb" re.match(pattern, string) # Out: <_sre.SRE_Match object; span=(0, 3), match='123'> match = re.match(pattern, string) ma...

pattern = r"(your base)" sentence = "All your base are belong to us." match = re.search(pattern, sentence) match.group(1) # Out: 'your base' match = re.search(r"(belong.*)", sentence) match.group(1) # Out: 'belong to us.' Searching is done anywhere in the ...

Grouping is done with parentheses. Calling group() returns a string formed of the matching parenthesized subgroups. match.group() # Group without argument returns the entire match found # Out: '123' match.group(0) # Specifying 0 gives the same result as specifying no argument # Out: '123' Arg...

Special characters (like the character class brackets [ and ] below) are not matched literally: match = re.search(r'[b]', 'a[b]c') match.group() # Out: 'b' By escaping the special characters, they can be matched literally: match = re.search(r'\[b\]', 'a[b]c') match.group() # Out: '[b]' T...

Replacements can be made on strings using re.sub. Replacing strings re.sub(r"t[0-9][0-9]", "foo", "my name t13 is t44 what t99 ever t44") # Out: 'my name foo is foo what foo ever foo' Using group references Replacements with a small number of groups can be made a...

MATLAB allows for several methods to index (access) elements of matrices and arrays: Subscript indexing - where you specify the position of the elements you want in each dimension of the matrix separately. Linear indexing - where the matrix is treated as a vector, no matter its dimensions. That ...

re.findall(r"[0-9]{2,3}", "some 1 text 12 is 945 here 4445588899") # Out: ['12', '945', '444', '558', '889'] Note that the r before "[0-9]{2,3}" tells python to interpret the string as-is; as a "raw" string. You could also use re.finditer() which works in...

Given some JSON file "foo.json" like: {"foo": {"bar": {"baz": 1}}} we can call the module directly from the command line (passing the filename as an argument) to pretty-print it: $ python -m json.tool foo.json { "foo": { "bar...
