Python String inbuilt Functions

Python String inbuilt Methods

Python has a set of built-in methods that we can use on strings

upper()

The upper() method returns a string where all characters are in upper case. Symbols and Numbers are ignored.

Syntax
string.upper()

n=”hello”
print(n.upper())

output:
HELLO

n=”hello world”
n1=n.upper()
print(n1)

output:
HELLO

n="hello"
print(n.upper())

n="hello world"
n1=n.upper()
print(n1)

Output:

HELLO
HELLO WORLD

lower()

The lower() method returns a string where all characters are in lower case. Symbols and Numbers are ignored.

Syntax
string.lower()

n=”HELLO”
print(n.lower())

output:
hello

n=”HELLO WORLD”
n1=n.lower()
print(n1)

output:
hello world

title()

The title() method returns a string where the first character in every word is upper case. Like a header, or a title.
If the word contains a number or a symbol, the first letter after that will be converted to upper case.

Syntax
string.title()

n=”HELLO HOW ARE YOU”
print(n.title())

Output:
Hello How Are You

n=”HELLO HOW ARE YOU”
n1=n.title()
print(n1)

Output:
Hello How Are You

n="HELLO HOW ARE YOU"
print(n.title())

n="HELLO HOW ARE YOU"
n1=n.title()
print(n1)

n="123 hello"
print(n.title())

n="123hello"
print(n.title())

Output:

Hello How Are You
Hello How Are You
123 Hello
123Hello
