find_character(string,char) returns integer Description Returns the position of the start of the first occurrence of the character char in string.

Common examples of array slicing are extracting a substring from a string of characters, the "ell" in "hello", extracting a row or column from a two-dimensional array, or extracting a vector from a matrix. Depending on the programming language, an array slice can be made out of non-consecutive elements.
Base 1: the first character is numbered 1, and so on. Any leading or trailing whitespace is removed from the string before searching. If the requested position is negative, this function will search the string counting from the last character. In other words, number = -1 is the same as asking for the last character of the string.
Python supports a wide variety of string operations. Strings in Python are immutable, so a string operation such as a substitution of characters, that in other programming languages might alter the string in place, returns a new string in Python. Performance considerations sometimes push for using special techniques in programs that modify ...
The -character is treated as a literal character if it is the last or the first (after the ^, if present) character within the brackets: [abc-], [-abc], [^-abc]. Backslash escapes are not allowed. The ] character can be included in a bracket expression if it is the first (after the ^, if present) character: []abc], [^]abc]. [^ ]

will match elements such as A[1], A[2], or more generally A[x] where x is any entity. In this case, A is the concrete element, while _ denotes the piece of tree that can be varied. A symbol prepended to _ binds the match to that variable name while a symbol appended to _ restricts the matches to nodes of that
