STR (string) returns the string representation of the object
List (SEQ)
Tuple (SEQ)

Attribute operation functions

The four built-in functions perform the following operations on the attributes of a namespace: existence, value, value, and deletion. It can be used for modules, classes, and instances.

 
If hasattr has an attribute, 1 is returned; otherwise, 0 is returned.
Getattr
Setattr
Delattr
 

Run Program

Import
Exec code [IN globaldict [, localdict]
Compile (string, filename, kind)
Execfile (filename [, globaldict [, localdict])
Eval (code [, globaldict [, localdict])
