What are strings in python with example?
StringsStrings in python are surrounded by either single quotation marks, or double quotation marks. Show
'hello' is the same as "hello". You can display a string literal with the Assign String to a VariableAssigning a string to a variable is done with the variable name followed by an equal sign and the string: Multiline StringsYou can assign a multiline string to a variable by using three quotes: ExampleYou can use three double quotes: a = """Lorem ipsum dolor sit amet, Try it Yourself » Or three single quotes: Example a = '''Lorem ipsum dolor sit amet, Try it Yourself » Note: in the result, the line breaks are inserted at the same position as in the code. Strings are ArraysLike many other popular programming languages, strings in Python are arrays of bytes representing unicode characters. However, Python does not have a character data type, a single character is simply a string with a length of 1. Square brackets can be used to access elements of the string. ExampleGet the character at position 1 (remember that the first character has the position 0): a = "Hello, World!" Try it Yourself » Looping Through a StringSince strings are arrays, we can loop through the characters in a string, with a ExampleLoop through the letters in the word "banana": for x in "banana": Try it Yourself » Learn more about For Loops in our Python For Loops chapter. String LengthTo get the length of a string, use the ExampleThe a = "Hello, World!" Try it Yourself » Check StringTo check if a certain phrase or character is present in a string, we can use the keyword
ExampleCheck if "free" is present in the following text: txt = "The best things in life are free!" Try it Yourself » Use it in an ExamplePrint only if "free" is present: txt = "The best things in life are free!" Try it Yourself » Learn more about If statements in our Python If...Else chapter. Check if NOTTo check if a certain phrase or character is NOT present in a string, we can use the keyword ExampleCheck if "expensive" is NOT present in the following text: txt = "The best things in life are free!" Try it Yourself » Use it in an Exampleprint only if "expensive" is NOT present: txt = "The best things in life are free!" Try it Yourself » Summary: in this tutorial, you’ll learn about Python string and its basic operations. Introduction to Python stringA string is a series of characters. In Python, anything inside quotes is a string. And you can use either single or double quotes. For example:
If a string contains a single quote, you should place it in double-quotes like this:
And when a string contains double quotes, you can use the single quotes:
To escape the quotes, you use the backslash (
The Python interpreter will treat the backslash character (\) special. If you don’t want it to do so, you can use raw strings by adding the letter
Creating multiline stringsTo span a string multiple lines, you use triple-quotes “””…””” or ”’…”’. For example:
It’ll output the following if you execute the program:
Using variables in Python strings with the f-stringsSometimes, you want to use the values of variables in a string. For example, you may want to use the value of the
To do it, you place the letter
Python
will replace the
The Concatenating Python stringsWhen you place the string literals next to each other, Python automatically concatenates them into one string. For example:
Output:
To concatenate two string variables, you use the operator
Output:
Accessing string elementsSince a string is a sequence of characters, you can access its elements using an index. The first character in the string has an index of zero. The following example shows how to access elements using an index:
How it works:
If you use a negative index, Python returns the character starting from the end of the string. For example:
The following illustrates the indexes of the string
Getting the length of a stringTo get the length of a string, you use the
Output:
Slicing stringsSlicing allows you to get a substring from a string. For example:
Output:
The The syntax for slicing is as follows:
The substring always includes the character at the The Python strings are immutablePython strings are immutable. It means that you cannot change the string. For example, you’ll get an error if you update one or more characters in a string:
Error:
When want to modify a string, you need to create a new one from the existing string. For example:
Output:
Summary
Did you find this tutorial helpful ? What is string with an example?A string is any series of characters that are interpreted literally by a script. For example, "hello world" and "LKJH019283" are both examples of strings. In computer programming, a string is attached to a variable as shown in the example below.
What are string types in Python?1) String. In Python, Strings are arrays of bytes representing Unicode characters. A string is a collection of one or more characters put in a single quote, double-quote or triple quote. In python there is no character data type, a character is a string of length one.
How many types of strings in Python explain with example?Python strings can be created with single quotes, double quotes, or triple quotes. When we use triple quotes, strings can span several lines without using the escape character. In our example we assign three string literals to a , b , and c variables.
Why are strings used in Python?Python strings are "immutable" which means they cannot be changed after they are created (Java strings also use this immutable style). Since strings can't be changed, we construct *new* strings as we go to represent computed values.
