Python String capitalize() Method

In Python, String capitalize() is an inbuilt function that returns a string copy with only its first character capitalized. If the string contains the first capital letter, the original string would be restored.

The syntax of the method is: str.capitalize()

Key Points :

• Return Type: String
• Parametric Values: Python capitalize() method does not contain any parameters.
• Conversion of the first string character to uppercase only.
• The original string does not change. The new variable name is saved for the modified string.
• If the string is empty, this method does not lead to an error for that string but returns an empty string for the result.
• When the feature uses a numeric string like “786,” the function returns the same value.

Below is the python program to demonstrate the capitalize() function:

# Python program to demonstrate the 
# use of capitalize() function
str = "Hi Technology Motivator";
print (str.capitalize())

When we run above the program, the outcome is as follows:

Output : Hi technology motivator

Python String capitalize() for Multiple Strings

Below is the python program to demonstrate the capitalize() for Multiple Strings.

# Python capitalize method Example
str = "hello, "
str2 = "technology motivator"
print(str.capitalize() + str2.capitalize())

When we run above the program, the outcome is as follows:

Hello, Technology motivator

Python capitalize() with other Object types like Number and None

We get an error when we use capitalize() for objects with different data types like a number or a Zero value. Let’s see the examples as well as the result:

Python capitalize() with Number:

Below is the python program to demonstrate the capitalize() function with a numeric value:

x = 786
print(x.capitalize())

When we run above the program, the outcome is as follows:

Traceback (most recent call last): 
File "main.py", line 2, in <module> 
print(x.capitalize()) 
AttributeError: 'int' object has no attribute 'capitalize'

Below are several other functions that we can use to work with string in Python 3
