# string are immutable. Which means at any point in our program we cannot change the 
# string once defined.

# string methods

# Here are some of the most common string methods. 
# A method is like a function, but it runs "on" an object. If the variable s is a string, t
# hen the code s.lower() runs the lower() method on that string object and returns the 
# result(this idea of a method running on an object is one of the basic ideas that make up Object Oriented Programming, OOP). 
# Here are some of the most common string methods:


# s.lower(), s.upper() - - returns the lowercase or uppercase version of the string
# s.strip() - - returns a string with whitespace removed from the start and end
# s.isalpha()/s.isdigit()/s.isspace()... -- tests if all the string chars are in the various character classes
# s.startswith('other'), s.endswith('other') - - tests if the string starts or ends with the given other string
# s.find('other') - - searches for the given other string(not a regular expression) within s, and returns the first index where it begins or -1 if not found
# s.replace('old', 'new') - - returns a string where all occurrences of 'old' have been replaced by 'new'
# s.split('delim') - - returns a list of substrings separated by the given delimiter. The delimiter is not a regular expression, it's just text. 'aaa, bbb, ccc'.split(', ') -> ['aaa', 'bbb', 'ccc']. As a convenient special case s.split()(with no arguments) splits on all whitespace chars.
# s.join(list) - - opposite of split(), joins the elements in the given list together using the string as the delimiter. e.g. '---'.join(['aaa', 'bbb', 'ccc']) -> aaa---bbb---ccc
