What are python built-in functions

Python built-in functions are as follows

Usage and instructions

1. abs(), returns the absolute value of a number.

2. all(), returns True if all elements in the set are true or the set is an empty set.

3. any(), if an element in the collection is true, returns True; an empty collection is False

4. ascii(), returns a string representing the object.

5. bin(), converts the integer into a binary string prefixed with "0b".

6. bool(), returns a Boolean value, either True or False.

7. bytearray(), returns a new byte array.

8. Callable (object) determines whether the object parameter can be called (callable refers to whether the object can be called using the method of () brackets)

9. chr(), return A string representing a character whose Unicode code point is the integer i. The opposite of the ord() function.

10. classmethod, convert the method into a class method.

11. compile, compile the source code into code or AST object. Code objects can be executed by exec() or eval(). source can be a normal string, a byte string, or an AST object.

12. dic(), creates a dictionary

13. divmod(a, b), takes two numbers as parameters and returns a quotient and remainder when using integer division A pair of numbers

14, enumerate (iterable, start = 0)

enumerate means enumeration, enumeration

For an iterable (iterable)/traversable Objects (such as lists, strings), enumerate forms an index sequence, and you can use it to obtain the index and value at the same time

enumerate is mostly used to get the count in a for loop

15, eval , turn a string into a dictionary

16, exec (object [, globals[, locals]]) The exec statement is used to execute Python statements stored in strings or files

17 , filter (function, iterable)

The filter function is used to filter the sequence

filter() applies the incoming function to each element in turn, and then decides based on whether the return value is True or False Keep or discard the element
