“`python
alphabet = ‘abcdefghijklmnopqrstuvwxyz’
print(alphabet[0:5]) # Output: ‘abcde’
print(alphabet[3:8]) # Output: ‘defgh’
“`

3. Changing Case:
Python provides built-in methods to convert alphabets to lowercase or uppercase. The lower() method converts all characters in a string to lowercase, while the upper() method converts them to uppercase. For example:

“`python
alphabet = ‘abcdefghijklmnopqrstuvwxyz’
print(alphabet.upper()) # Output: ‘ABCDEFGHIJKLMNOPQRSTUVWXYZ’
print(alphabet.lower()) # Output: ‘abcdefghijklmnopqrstuvwxyz’
“`

4. Checking Alphabets:
We can use various methods to check if a character or a string contains alphabets only. The isalpha() method returns True if all characters in a string are alphabets; otherwise, it returns False. For example:

“`python
string = ‘HelloWorld’
print(string.isalpha()) # Output: True

string = ‘Hello World 123’
print(string.isalpha()) # Output: False
“`

5. Joining Alphabets:
The join() method allows us to concatenate alphabets from a sequence into a single string. For example, we can join all lowercase alphabets with a specific delimiter:

“`python
delimiter = ‘-‘
alphabets = ‘abcdefghijklmnopqrstuvwxyz’
joined = delimiter.join(alphabets)
print(joined) # Output: ‘a-b-c-d-e-f-g-h-i-j-k-l-m-n-o-p-q-r-s-t-u-v-w-x-y-z’
“`
