String Operations in Python

First string operation to discuss is concatenation. This operation allows us to combine multiple strings together.

1var book = "The Great Gatsby";
2var author = "F. Scott Fitzgerald";
3
4var sentence = book + "was written by " + author;
5
6console.log(sentence); //prints "The Great Gatsby was written by F. Scott Fitzgerald"

Multiplication operator *, allows to create a string which repeats itself multiple times. For example,

1name = "Chris"
2
3print(name*3) #prints "ChrisChrisChris"

Other string operations in Python are all implemented through string methods. Let's see some of the examples below.

• len() method tells us the length of string.
• count() method tells about the number of times a specified value occurs in string.
• upper() method converts all the characters in the string to uppercase.

Example usage of these operations can be found in the code block below.

1var book = "The Great Gatsby";
2var author = "F. Scott Fitzgerald";
3
4console.log(book.length); // prints 16
5console.log(author.indexOf("z")); // prints 12
6console.log(author.indexOf("Scott")); // prints 3
7console.log(author.toLowerCase()); // prints "f. scott fitzgerald"
