String methods

Every string in Python brings a list of functions to work with it. As the functions are contained within the string they are also called methods. They are used by adding the . to the string variable followed by the method name.

Below you find a few of the available methods:

Changing case:

s = 'Manipulating Strings '
s.upper()
s.lower()

Removing whitespace at both ends:

s.strip()

Cutting a string into columns:

s.split(' ')

Searching for substrings:

s.find('ing')

The method returns the start index of the match. The result -1 means that no match has been found.

Replacing substrings:

s.replace('Strings','text')

Removing whitespace at both ends:

s.startswith('Man')
s.endswith('ings')
