String Methods

In this tutorial, we will learn about different methods that can be used with Strings, like finding the length of a string, counting occurrences of a sub-string in a string, joining elements of an iterable and returning a string, checking if a string ends with the sub-string, etc.

The following table presents all the String methods with the link to their respective tutorial, and description for each method.

String Method NameDescription
capitalize()Returns a new string with the first character in the given string converted to upper case.
casefold()Returns a new string with the given string value converted into lower case.
center()Returns a new string with specified length and the given string is centered in this new string.
count()Returns the number of occurrences of a specified value in a string.
encode()Returns a new string which is created from the given string, encoded using specified encoding standard.
endswith()Returns True if the string ends with the specified value, or False if the string does not end with the specified value.
expandtabs()Sets the tab size for the tab characters in the string.
find()Returns the index of the first occurrence of specified value in given string.
format()Formats specified values in a string.
format_map()Formats specified values in a string.
index()Searches the string for a specified value and returns the position of where it was found.
isalnum()Returns True if all characters in the string are alphanumeric.
isalpha()Returns True if all characters in the string are in the alphabet.
isdecimal()Returns True if all characters in the string are decimals.
isdigit()Returns True if all characters in the string are digits.
isidentifier()Returns True if the string is an identifier.
islower()Returns True if all characters in the string are lower case.
isnumeric()Returns True if all characters in the string are numeric.
isprintable()Returns True if all characters in the string are printable.
isspace()Returns True if all characters in the string are whitespaces.
istitle()Returns True if the string follows the rules of a title.
isupper()Returns True if all characters in the string are upper case.
join()Joins the elements of an iterable to the end of the string.
ljust()Returns a left justified version of the string.
lower()Converts a string into lower case.
lstrip()Returns a left trim version of the string.
maketrans()Returns a translation table to be used in translations.
partition()Returns a tuple where the string is parted into three parts.
replace()Returns a string where a specified value is replaced with a specified value.
rfind()Searches the string for a specified value and returns the last position of where it was found.
rindex()Searches the string for a specified value and returns the last position of where it was found.
rjust()Returns a right justified version of the string.
rpartition()Returns a tuple where the string is parted into three parts.
rsplit()Splits the string at the specified separator, and returns a list.
rstrip()Returns a right trim version of the string.
split()Splits the string at the specified separator, and returns a list.
splitlines()Splits the string at line breaks and returns a list.
startswith()Returns true if the string starts with the specified value.
strip()Returns a trimmed version of the string.
