Built-in functions

Python has many built-in functions that are always available in any part of the program. The print() function that we use to send output to the screen is a built-in function.

Help for any built-in function is available using help(function).

Built-in functions that are commonly used with numbers are:

abs(x)         # returns absolute value of x
pow(x, y)      # returns value of x raised to y 
min(x1, x2,...)# returns smallest argument
max(x1, x2,...)# returns largest argument 
divmod(x, y)   # returns a pair(x // y,x % y)
round(x [,n])  # returns x rounded to n digits after . 
bin(x)         # returns binary equivalent of x
oct(x)         # returns octal equivalent of x
hex(x)         # returns hexadecimal equivalent of x
