The enclosed text becomes a string literal, which Python usually ignores (except when it is the first statement in the body of a module, class or function; see docstring). Elixir. The above trick used in Python also works in Elixir, but the compiler will throw a warning if it spots this.
COBOL uses the STRING statement to concatenate string variables. MATLAB and Octave use the syntax "[x y]" to concatenate x and y. Visual Basic and Visual Basic .NET can also use the "+" sign but at the risk of ambiguity if a string representing a number and a number are together. Microsoft Excel allows both "&" and the function "=CONCATENATE(X,Y)".
<string>.split(separator[, limit]) splits a string on separator, optionally only up to a limited number of substrings Description Splits the given string by occurrences of the separator (itself a string) and returns a list (or array) of the substrings.

Reducing the range of any index to a single value effectively eliminates that index. This feature can be used, for example, to extract one-dimensional slices (vectors: in 3D, rows, columns, and tubes [1]) or two-dimensional slices (rectangular matrices) from a three-dimensional array. However, since the range can be specified at run-time, type ...
In computer science, interning is re-using objects of equal value on-demand instead of creating new objects. This creational pattern [1] is frequently used for numbers and strings in different programming languages. In many object-oriented languages such as Python, even primitive types such as integer numbers are objects. To avoid the overhead ...
bind can now also be derived with just a formula, then used to feed List values through a pipeline of monadic functions: The List monad can greatly simplify the use of multivalued functions, such as complex roots. [29] (xlist >>= f) = join ∘ (map f) xlist One application for this monadic list is representing nondeterministic computation.
The distinct values are stored in a string intern pool. The single copy of each string is called its intern and is typically looked up by a method of the string class, for example String.intern() [2] in Java. All compile-time constant strings in Java are automatically interned using this method. [3]
