Built-in Functions in Python (2024)
Note: Some functions have minimal changes compared to Python 2.x. They may directly link to the built-in function explanations in the Python 2.x tutorial, so be sure to pay attention to the details.
The following are Python's built-in functions:

any() | Returns True if any element of the iterable is true. |
ascii() | Returns a readable version of an object, replacing non-ASCII characters with escape sequences. |
bin() | Converts an integer to its binary equivalent. |
bool() | Converts a value to True or False. |
bytearray() | Returns an array of bytes. |
bytes() | Returns an immutable bytes object. |

staticmethod() | Converts a method into a static method. |
str() | Returns a string object. |
sum() | Sums the items of an iterable. |
super() | Returns a proxy object that delegates method calls to a parent or sibling class. |
tuple() | Returns a tuple object. |
type() | Returns the type of an object. |
