Python built-in functions and uses

Python has a number of functions built into it that can be called directly

ABS () take absolute value

ABS (-29)

When calling a function, if the number of incoming arguments is incorrect, a typeerror error is reported, and Python will tell you explicitly that abs () has only one parameter, but gives two parameters

If the number of arguments passed in is correct, the type of the single parameter cannot be accepted by the function, the TypeError error is reported, and an error message is given: STR is the wrong parameter type

Max function, Max can accept any number of arguments and return the largest one

Data type conversions

Python's built-in common functions also include data type conversion functions, such as the Int () function to convert other data types to integers
