capitalize() : First char of the input string is converted to upper case

my_str="welcome to plus2net.com"
print(my_str.capitalize()) # Welcome to plus2net.com

We can't change the first char if it is a number

my_str="345 is the number"
print(my_str.capitalize()) # 345 is the number

capitalize()

Parameters

No parameter is taken by this method.

capitalize(),title() & upper()

capitalize() only changes the first character, while title() capitalizes each word, and upper() converts all characters to uppercase.

text = "hello world"
print(text.capitalize())  # Hello world
print(text.title())       # Hello World
print(text.upper())       # HELLO WORLD

Handling Special Characters:

text = "@welcome"
print(text.capitalize())  # @welcome (special character remains unchanged)

Applying to Multi-sentence Strings:

text = "hello. this is a test."
print(text.capitalize())  # Hello. this is a test.
