1. Ultimate Reference to Python String Methods
In Python, the functions that are solely dependent or rely on their parent class are called methods and such kinds of methods are available for strings in Python. Usually, these string methods are built-in in Python programming language and we can use them to work with strings as required. The table below contains all the built-in string methods in Python language and serves as an ultimate and up-to-date guide or reference.
2. Search Ultimate Reference For Python String Methods
Search Python string methods from the below table, which is an ultimate and up-to-date guide or reference, for the developers. Please note that the parameters or arguments of some string methods might be optional, so don't get carried away while writing your Python programs.
2.1. Alphabetical Reference
| Method | Description |
| capitalize() | This string method in Python converts the first letter of a string to uppercase. |
| casefold() | To convert a string to lowercase, we can use this Python method. |
| center() | To center a string in a field of a specified width, we use this Python method. |
| count() | This Python method counts the number of occurrences of a substring in a string. |
| encode() | In order to get an encoded string in bytes, we utilize this Python method. |
| endswith() | We use this method to check if the string ends with the provided suffix and returns True. |
| expandtabs() | Sets the tab size of the string to the required string using this Python method. |
| find() | This Python method is used to find the first occurrence of a substring in a string and returns its index or return -1. |
| format() | To format a string using template-style syntax, we use this Python method. |
| format_map() | This Python method formats a string using a mapping object. |
| index() | This Python method is similar to the find() function but raises an exception if the substring is not found in a string. |
| isalnum() | If all characters in the string are alphanumeric, this Python method returns True. |
| isalpha() | If all characters in the string are in the alphabet, this Python method returns True. |
| isascii() | This Python method returns True if all characters in the string are ASCII characters. |
| isdecimal() | If all characters in the string are decimals, this Python method returns True. |
| isdigit() | This Python method returns True if all characters in the string are digits. |
| isidentifier() | If the string is an identifier, this Python method returns True. |
| islower() | If all characters in the string are lowercase, the Python islower() method returns True. |
| isnumeric() | This Python method returns True if all characters in the string are numeric. |
| isprintable() | This Python method returns True if all characters in the string are printable. |
| isspace() | If all characters in the string are whitespaces, this Python method returns True. |
| istitle() | If the string follows the rules of a title, this Python method returns True. |
| isupper() | This Python method returns True if all characters in the string are upper case. |
| join() | This Python method converts the elements of an iterable into a string. |
| ljust() | To return a left-justified version of the string, we use this Python method. |
| lower() | To convert a string into lowercase, we use this Python method. |
| lstrip() | The leading specified characters are removed using this Python method. |
| maketrans() | To Return a translation table for strings' translations, we use this Python method. |
| partition() | This Python method returns a 3-tuple containing the separator and the part before and after the separator. |
| removeprefix() | This Python method removes the prefix from a string and returns the remaining string. |
| removesuffix() | To remove the suffix from a string, we use this Python method. |
| replace() | To replace a substring with a specified value in a string, we use this Python method. |
| rfind() | It returns -1 if the substring is not found unlike the rindex() Python method, otherwise, it returns the index of the last occurrence of the substring in a string. |
| rindex() | To find the index of the last occurrence of a substring in a string, we use this Python method and it works similarly to the rfind() function but gives an error if the substring is not found. |
| rjust() | To return a right justified version of the string, we use this Python method. |
| rpartition() | This Python method returns a 3-tuple containing the separator, the part before the separator, and the part after it in the string. |
| rsplit() | This Python method returns a list of specified words in a string using a separator. |
| rstrip() | The trailing characters are removed in a string using this Python method. |
| split() | To split the string at the specified separator, and return a list, we use this Python method. |
| splitlines() | To return a list of strings at line breaks, we use this Python method. |
| startswith() | If the string starts with the specified prefix, this Python method returns True. |
| strip() | This Python method removes beginning and trailing characters from a string as specified in the method argument. |
| swapcase() | The lowercase letter becomes uppercase letters and vice versa using this Python method. |
| title() | To convert the first character/letter of each word of the string to uppercase, we use this Python method. |
| translate() | To translate a string using a given translation table, we use this Python method. |
| upper() | This Python method converts a string into upper case. |
| zfill() | This Python method pads a numeric string with zeros(0) on the left to fill a specified width. |
3. Dynamically Get Python String Methods
There are various methods in Python that deal specifically with the strings. To get an up-to-date and ultimate reference list of all the string related methods, use the below script.
Get All String Methods
# Get the list of string methods
string_methods = [
method
for method in dir(str)
if callable(getattr(str, method))
and not method.startswith('__')
]
# Print the list of string methods
print(string_methods)
Note:
Importantly, it is to note that these string methods are totally different from those of built-in Python functions, so make sure to keep this in mind.
