4.5 Other String Operations

In the previous sections, we saw some basic and common operations that were used to deal with strings. This included:

• Indexing Strings
• Slicing Strings
• Formatting Strings

In this section, we'll see some other operations that can be performed on a string.

Multiplication (the * operator)

Characters of a string can be multiplied using the * operator. As such, the characters of string are repeated the number of times it was multiplied with.

CodeOutput

string = 'abc'

print(string * 3)

abcabcabc

It is worth noting that a new string is created on multiplication and old string remains as is.

CodeOutput

string = 'abc'
new_string = string * 3

print(string)
print(new_string)

abc
abcabcabc

len() function

The built-in len() function is used to return the length of any sequence. Since string is a sequence of characters too, it can return the number of characters in the string.

CodeOutput

string = 'Hello Python'
length = len(string)
print(f'This string has {length} characters.')

This string has 11 characters.

Note

Keep in mind that "space" is also considered a character.
