capitalize() Syntax

The syntax of the capitalize() method is:

string.capitalize()

capitalize() Parameter

The capitalize() method doesn't take any parameter.

capitalize() Return Value

The capitalize() method returns:

• a string with the first letter capitalized and all other characters in lowercase.

Example 1: Python capitalize()

sentence = "python is AWesome."

# capitalize the first character 
capitalized_string = sentence.capitalize()

print(capitalized_string)

Output

 Python is awesome.

In the above example, we have used the capitalize() method to convert the first character of the sentence string to uppercase and the other characters to lowercase.

Here, sentence.capitalize() returns "Python is awesome" which is assigned to capitalized_string.

Example 2: capitalize() Doesn't Change the Original String

The capitalize() method returns a new string and doesn't modify the original string. For example:

sentence = "i am learning PYTHON."

# capitalize the first character 
capitalized_string = sentence.capitalize()

# the sentence string is not modified 
print('Before capitalize():', sentence)

print('After capitalize():', capitalized_string)

Output

Before capitalize(): i am learning PYTHON.
After capitalize(): I am learning python.

Here, the capitalize() method doesn't modify the original sentence string.
