543. To quote the Python 2.x documentation: A prefix of 'b' or 'B' is ignored in Python 2; it indicates that the literal should become a bytes literal in Python 3 (e.g. when code is automatically converted with 2to3). A 'u' or 'b' prefix may be followed by an 'r' prefix. The Python 3 documentation states:In this article, we’ll cover useful Python string methods for manipulating string (str) objects — such as joining, splitting and capitalizing. Each method described …The simplest way to append to a string in python is to use the + (plus) operator. Instead of functioning as a mathematical addition, in Python the + operator is used to concatenate strings together. This means that you can use it to append one string to another. Here’s an example of the + operator in practice:temp1 = re.findall(r'\d+', line2) # find number of digits through regular expression. res2 = list(map(int, temp1)) print(res2) you can search all the integers in the string through digit by using findall expression. In the second step create a list res2 and add the digits found in string to this list. Share. String indexing in Python is zero-based: the first character in the string has index 0, the next has index 1, and so on. The index of the last character will be the length of the string minus one. For example, a schematic diagram of the indices of the string 'foobar' would look like this: String Indices.

What is a Docstring? A docstring is a string literal that occurs as the first statement in a module, function, class, or method definition.

We saw that lists and strings have many common properties, such as indexing and slicing operations. They are two examples of sequence data types (see Sequence Types — list, tuple, range). Since Python is an evolving language, other sequence data types may be added. There is also another standard sequence data type: the tuple.

Python strings are immutable, you change them by making a copy.

You can extract a substring from a string by slicing with indices that get your substring as follows: string [start:stop:step] start - The starting index of the substring. stop - The final index of a substring. step - A number specifying the step of the slicing.
