Variables, Expressions and Statements: Values,
Variables and keywords; Operators and Operands in Python: (Arithmetic,
relational and logical operators), operator precedence, Expressions and
Statements (Assignment statement); Taking input (using raw_input() and
input()) and displaying output (print statement); Putting Comments.
Functions: Importing
Modules (entire module or selected objects), invoking built in
functions, functions from math module (for example, ceil, floor, fabs,
exp, log, log10, pow, sqrt, cos, sin, tan, degrees, radians), using
random() and randint() functions of random module to generate random
numbers, composition.
Defining functions,
invoking functions, passing parameters (default parameter values,
keyword arguments), scope of variables, void functions and functions
