In This Article You Will Learn About Python String Method Isspace(), istitle(), join(), just(), lower()
Python String Method – Before moving ahead, let’s know a little bit about methods Isdigit(), Isidentifier(), Islower(), Isnumeric() And Isprintable()
isspace() method – It returns True if all the characters in a string are whitespaces, otherwise False.
Syntax - string.isspace() Parameter Values - Parameter values.
Example 1- Check if all character contains whitespace.
x = ' ' y = x.isspace() print(y)
Example 2- Check if all character not found whitespace.
x = 'H' y = x.isspace() print(y)
istitle() method – It returns True if all words in a given string start with a upper-case letter, and the rest of the words are lower-case letters, otherwise False. It ignores symbols and numbers.
Syntax - string.istitle() Parameter Values - No parameters.
Example 1- Check if each word starts with an upper-case letter –
x = 'Hello, Python World' print(x.istitle())
Example 2- Check if each word starts with an upper-case letter –
x = 'PYTHON' z = 'Python' v = 'Hi 568' c = 'Are, @, !' print(x.istitle()) print(z.istitle()) print(v.istitle()) print(c.istitle())
join() method – It returns string by joining all separated string of an element.
Syntax - string.join( iterable ) Parameter Values - iterable - It is required. It contains iterable object which returned all the values in string. Types of iterable - List, Tuple, String, Set and Dictionary.
Example 1- Using join() method with different iterable. In other words, adding string in tuple.
x = ('Hello', 'Python')
y = '**'
z = y.join(x)
print(z)
Example 2- Adding string in list.
x = ['2', '6', '8', '9'] y = '%' z = y.join(x) print(z)
Example 3- Adding string in set.
x = {'6', '8', '2', '9'}
y = '--'
z = y.join(x)
print(z)
Note: Order is random. A set is an unordered collection of items that’s why it will show different output every time.
Example 4- Adding string in dictionary.
x = {'name' : 'Alex', 'add' : 'NYC'}
y = '=='
z = y.join(x)
print(z)
Note: A dictionary as an iterable, returned only the keys not values.
Ijust() method – It returns a left-justified string of a given minimum width.
Syntax - string.ljust(width[, fillchar]) or simply it can be string.ljust( length, character ) Parameter Values - width - If width is less than or equal to length of given string then it returns original string. fillchar - It used to fill remaining space of the width. Parameter Values – length - It is required argument. The length of the returned string. character - It is optional argument. A character to fill the missing space (to the right of the string). Default is taken as " " (space).
Example 1- Left justify string of minimum width.
x = 'python' z = 10 print(x.ljust(z))
Example 2- Left justify string and fill the remaining spaces.
x = 'python' z = 10 y = '<' print(x.Ijust(z, y))
lower() method – It returns given string in lower case. It ignores Symbols and Numbers.
Syntax - string.lower() Parameter Values - No parameter values.
Example – Convert all character of given string in lower-case.
x = 'HELLO! PYTHON' print(x.lower())
