7.Strings Indexing & Slicing

Slicing Strings:

You can return a range of characters by using the slice syntax.

Specify the start index and the end index, separated by a colon, to return a part of the string.

** Get the characters from position 2 to position 5 (not included):**

b = "Hello, World!"
print(b[2:5])
Output : llo

Slice From the Start
By leaving out the start index, the range will start at the first character:

Get the characters from position 2, and all the way to the end:

b = "Hello, World!"
print(b[:5])
Output = Hello

Negative Indexing
Use negative indexes to start the slice from the end of the string:

**Get the characters:

From: "o" in "World!" (position -5)

To, but not included: "d" in "World!" (position -2):**

`b = "Hello, World!"
print(b[-5:-2])

Output =orl`

Python - Modify Strings

The upper() method returns the string in upper case

a = "Hello, World!"
print(a.upper())
Output =HELLO, WORLD!

The **lower() method returns the string in lower case:**

The lower() method returns the string in lower case:

`a = "Hello, World!"
print(a.lower())

Output) =hello, world!`

The strip() method removes any whitespace from the beginning or the end:

`a = " Hello, World! "
print(a.strip())

Output =Hello, World!`

Replace String
Example
The replace() method replaces a string with another string:

`a = "Hello, World!"
print(a.replace("H", "J"))

Output =Jello, World!
`
Split String

The split() method returns a list where the text between the specified separator becomes the list items.

Example:

The split() method splits the string into substrings if it finds instances of the separator:

'a = "Hello, World!"
print(a.split(","))
['Hello', ' World!']
Output =['Hello', ' World!']'

`Indexing :

fruits = ['apple', 'banana', 'cherry']

x = fruits.index("cherry")

print(x)
Output =2`
