The **`isalpha()` method** of the `String` class in Python is a built-in method that checks if a specified argument includes only alphabets (A-Z and/or a-z).

# 
## Syntax
```
string.isalpha()
```
## Parameters

The `isalpha()` method takes no parameters.

## Return type

`isalpha()` method returns `true` if all characters in the string are alphabets. Otherwise, it returns `false`.

The figure below shows the different return types of the `isalpha()` method for different arguments:

```
string = 'Maria'
string.isalpha() #returns true
   
string = 'Maria04'
string.isalpha() #returns false

string = 'Maria Elijah'
string.isalpha() #returns false
```
## Code

The following program shows how to use the `isalpha()` method.

# using isalpha()
  
# Given string
string='_Maria'
print(string.isalpha())

string1 = 'Maria Elijah'
count=0
  
  
# Iterate the string and check for alphabets
# Increment the counter if an alphabet is found
# Finally print the result
for x in string1:
    if (x.isalpha()) == True:
        count+=1
print(f"The string contains {count} alphabet")



## Explanation

The code above first uses the `isalpha()` method on the `string` variable. Next, the code iterates over each character in a string, and uses the `isalpha()` method to check if the current character is an alphabet or not.

What is the String.isalpha() method in Python?

Checks if a string contains only alphabets and returns true if so; otherwise, returns false.
