Python built-in Method - ascii()

The ascii() method is a built-in function in Python that returns a string containing a printable representation of an object. The string returned by ascii() contains only ASCII characters, which are the standard characters used in the ASCII character set.

Here is the syntax for ascii() method:

ascii(obj)

where obj is any object that can be represented as a string.

Here are some examples of how to use ascii():

print(ascii('hello'))  # Output: 'hello'
print(ascii('áéíóú'))  # Output: '\xe1\xe9\xed\xf3\xfa'

In the first example, the string 'hello' contains only ASCII characters, so the ascii() method returns the string 'hello'. In the second example, the string 'áéíóú' contains non-ASCII characters, so the ascii() method returns a string containing the corresponding ASCII codes for those characters.

The ascii() method can be useful when you need to ensure that a string contains only ASCII characters, for example when working with legacy systems that do not support non-ASCII characters. However, it is important to note that the ascii() method can be lossy, since it replaces non-ASCII characters with ASCII codes, which may not always be a valid representation of the original string.
