Capitalize first letter of all the words in a string in Python

In this tutorial, I am going to capitalize the first letter of all words in a string using different methods. In Python string is Immutable, so when you use any method to manipulate string it will return as a new string.

Method 1

In this method, I will use the .title() function for capitalizing a word’s first letter in a string.

Code

str = 'the one piece is real'
result = str.title()
print(result)

Method 2

In this method, importing string which is a built-in module in Python is necessary. Python string module has some classes and utility functions for string manipulation. Here I will use the string.capwords() which takes a string as a parameter and capitalizes all the word’s first letters in a string.

Code

import string
str = 'the one piece is real'
result = string.capwords(str)
print(result)

Method 3

In this method, I will be using .capitalize() function. At first, I have to use the .split() function which will split the string from spaces and store it into a list. Then using a for loop we will iterate the list and store it in a variable with the .capitalize() function applied which will capitalize the first letter of a word and adding it with a space. It will give an output that capitalizes all the word’s first letters in the string.

Code

s = 'the one piece is real'
result = ""
words = s.split()
for i in words:
    result = result + " " + i.capitalize()

print(result)

Output

The One Piece Is Real
