Introduction of Python
Python Built-in Functions
Python provides number of built-in functions, that can be used to perform different type of operations.
Built-in function like abs() , all() , any() , sorted()
, sum() , pow() , round() , divmod()
, chr() , ord() , bin() , hex() , oct()
, max() , min()and len() are widely used for operations.
Built-in Functions
| Function Name | Descriptions |
|---|---|
| abs(x) | Return the absolute value of the argument. |
| all(iterable) | Return True if bool(x) is True for all values x in the iterable. |
| all(iterable) | Return True if bool(x) is True for all values x in the iterable. |
| any(iterable) | Return True if bool (x) is True for any x in the iterable. |
| sorted(iterable, key=None, reverse=False) | Return a new list containing all items from the iterable in ascending order. |
| sum( iterable, start) | Return the sum of a 'start' value (default: 0) plus an iterable of numbers |
| pow(base,exp,mod) | Equivalent to base**exp with 2 arguments or base**exp % mod with 3 arguments |
| round(number,ndigits) | Round a number to a given precision in decimal digits. |
| divmod(x,y) | Return the tuple (x//y, x%y). Invariant: div*y + mod == x. |
| chr(i) | Return a Unicode string of one character with ordinal i; 0 <= i <= 0x10ffff. |
| ord(c) | Return the Unicode code point for a one-character string. |
| bin(number) | Return the binary representation of an integer. |
| hex(number) | Return the hexadecimal representation of an integer. |
| oct(number) | Return the octal representation of an integer. |
| max(iterable, *) | With two or more arguments, return the largest argument. |
| min(iterable, *) | With two or more arguments, return the largest argument. |
| len(obj) | Return the number of items in a container. |
