Python title() function | Why do we use Python String title() function? | (2024)

Python includes a wide range of string handling functions. String handling methods include converting a string to lowercase, uppercase, and so on. Another such method is the title case method. Python title() function is used to convert an input string to a title case i.e. converting the first alphabet of each word to uppercase and the rest into lowercase. Let us understand about Python title() in the article below.

Definition

• The Python title() function is used to change the initial character in each word to Uppercase and the subsequent characters to Lowercase and then returns a new string.
• Python title() method returns a title-cased string by converting the initial letter of each word to a capital letter.

title() Syntax

Python title() function follows the below-mentioned syntax:

 
string.title() 

title() Parameters

This function does not accept any parameter. If any parameter is passed, the function throws an exception.

Return value from title()

The title() string function returns a new string that contains a title-cased version of the input string. In Layman terms, this function capitalizes the first letter of each word in the string.

Note – Python title() function ignore any non-alphabetic characters. It ignores any numbers and special characters in the string.

Example 1: How Python title() works?

Example

 
# Python program to illustrate title()my_str = 'Hello, welcome to the museum'print(my_str.title())my_str = '101 hacks for python'print(my_str.title())my_str = 'I AM an MBA STUdent'print(my_str.title())my_str = '262131 @%&*'print(my_str.title()) 

Output

 
Hello, Welcome To The Museum101 Hacks For PythonI Am An Mba Student262131 @%&* 

Example 2: title() with apostrophes

This function utilizes a straightforward, language-independent definition of a word as groups of consecutive letters. As a result, apostrophes (‘) are treated as a word boundary.

When using apostrophes and numbers in between words, the Python title() method may show unexpected and strange behavior. The initial letter following any number or special character (such as an apostrophe) is changed to an upper-case letter. Look at the below example to understand more:

Example

 
# Python program to illustrate title()my_str = "He's here, isn't he? "print(my_str.title())my_str = 'Pyt0n Progr6mm1ng'print(my_str.title()) 

Output

 
He'S Here, Isn'T He?Pyt0N Progr6Mm1Ng 

We don’t want this to happen most of the time. You may use regex or the string.capwords() to fix this problem.

Example 3: Using Regex or string.capwords() to Title Case String

Example

 
# Using regeximport redef titlecasefunct(s): return re.sub(r"[A-Za-z]+('[A-Za-z]+)?", lambda mo: mo.group(0)[0].upper() + mo.group(0)[1:].lower(), s)txt = "They're Jimmy's friends. Let's give them 10dollars each"print(titlecasefunct(txt))print('')# Using capwords()import strings = "I'll be ca11ing you, won't I?"val = string.capwords(s)print(val) 

Output

 
They're Jimmy's Friends. Let's Give Them 10Dollars EachI'll Be Ca11ing You, Won't I? 

Frequently Asked Questions

Q1. What is title() in Python?

A title-cased string is the one in which every first letter of the word is an uppercase character. Python title() function is used to convert an input string to a title case i.e. converting the first alphabet of each word to uppercase and the rest into lowercase. Python title() function ignore any non-alphabetic characters. It ignores any numbers and special characters in the string.

Q2. How do you add a title in Python?

To add a title to an input string in Python, we implement the title() string class method. Python title() function follows the below-mentioned syntax:

 
string.title() 

The title() string function returns a new string that contains a title-cased version of the input string. In Layman terms, this function capitalizes the first letter of each word in the string.

Example

 
txt = 'i have to reach office by 9:00'print(txt.title())txt = 'HELLO Students, WELcome BAck'print(txt.title())txt = '101hacks with python'print(txt.title()) 

Output

 
I Have To Reach Office By 9:00Hello Students, Welcome Back101Hacks With Python 

Q3. What is the difference between title and capitalize in Python?

Python capitalize() and title() are 2 inbuilt functions used for string handling.

• title() – Python title() method returns a title cased string by converting the initial letter of each word to a capital letter.
• capitalize() – The capitalize() method only capitalizes the first character of the string i.e. it converts only the first letter of the input string into uppercase and others to lowercase.

Example

 
txt = 'i have to reach office by 9:00'print(txt.title())print(txt.capitalize())print('')txt = 'HELLO Students, WELcome BAck'print(txt.title())print(txt.capitalize())print('')txt = '101hacks with python'print(txt.title())print(txt.capitalize()) 

Output

 
I Have To Reach Office By 9:00I have to reach office by 9:00Hello Students, Welcome BackHello students, welcome back101Hacks With Python101hacks with python 

Q4. Difference between istitle() and title() function in Python?

• Python title() – The Python title() function is used to change the initial character in each word to Uppercase and the subsequent characters to Lowercase and then returns a new string.
• Python istitle() – Python istitle() function is used to return value TRUE if the input string is a titlecased string else it returns FALSE. The istitle() method disregards any symbols or digits in a provided string.

Example

 
txt = 'i have to reach office by 9:00'print(txt.title())print(txt.istitle())print('')txt = 'Hello Students, Welcome Back'print(txt.title())print(txt.istitle())print('')txt = '101hacks with python'print(txt.title())print(txt.istitle()) 

Output
