The method takes two parameters: width and fillchar. If the width is equal to or less than the length of the string len(s), the original string is returned. This method returns a centered string padded by a given fillchar and width. This method returns a copy of the string with its first character capitalized and the others in lowercase.Įxample 1: > "i Enjoy traveling. Python String Methods that Return a Modified Version of a String str.capitalize() We can create a string version of an object out of a particular object by explicitly calling its _str_() method, as seen in the example below: price = 15.25 print ( dir (price ) ) print ( type (price ) ) print ( type (price. Hhowever, the str constructor converts it to string object.Įvery Python object has the str() dunder method, which computes a string version of that object.Ī simple peek at an object’s properties and methods with the dir() built-in function will show the _str_() method, among others. The variable number was initially an int object. Here’s the output of the above code: 23 is an object of 23 is an object of Number = str (number ) print (number, 'is an object of ', type (number ) ) The str() constructor can take an object as argument and implicitly calls the object’s dunder _str_() to return a string representation of that object: number = 23 print (number, 'is an object of ', type (number ) ) print ( dir (number ) ) The Python str class can be used to create string objects. The str() constructor returns a printable string version of a given object. Strings can also be created through the use of the str constructor from other objects. Here’s a string literal with triple quotes: string_three = """ Here’s a string literal with double quotes: string_two = "String two" Here’s a string literal with single quotes: string_one = 'String one' Triple quotes allows for strings that can span multiple lines without the use of a backslash to escape newline characters. When a single quote is used for a string literal, a double quote can be embedded without any errors, and vice versa. Python string literals can be written with single, double or triple quotes. Written text in Python is created by string objects or string literals. This means that string data types, like other types, are built into the Python interpreter. Strings are one of Python’s built-in types. code(encoding=’utf-8′, errors=’strict’).Python Bytes Methods that Return a String.Python String Methods for Returning a Boolean Value.Python String Methods for Performing Queries on a String.Python String Methods for Joining and Splitting Strings.str.encode(encoding=’utf-8′, errors=’strict’).
Note: unlike Java or other programming languages, Python doesn’t support a character data type. Also note that the old str() class from Python 2 has become the bytes() class in Python 3.Ī Python string looks like this: greeting = "Hello, World!" Python 2 uses the unicode() function to do the same things we’ll discuss here. An “immutable” string is one that, once declared, cannot be modified instead, another string object is created.
Strings are a sequence of immutable unicode characters, enclosed within single, double or triple quotes.
Like every other programming language, Python has its own unique implementation of the string data type. They constitute sequences that, when grouped together, can form words, sentences, and so on. Strings are an integral part of every programming language, and are one of the most-used data types in Python. We’ll also end with a little challenge you should try to assess how much you’ve understood the topic. Each method described in this article will include an explanation with a relevant example. In this article, we’ll cover useful Python string methods for manipulating string ( str) objects - such as joining, splitting and capitalizing.
