Study Guide for Test 1 (22 Feb 2017)
* The test will be on Wednesday, 22 Feb 2017. The test will be
held during scheduled class times. It will be closed book and
closed notes.
* You are responsible for the material in Liang's book from chapters
1 through 6.
* Questions are of two types - write code or interpret code.
* You will define variables, i.e. write meaningful variable names and
their values.
* You will evaluate expressions given certain input values. This will
involve all the operators that were discussed in class not bitwise
or shift.
* You will write Boolean expressions that evaluate to True given a
set of conditions.
* You will create truth tables for Boolean expressions that will
involve Boolean operators not, and, or, xor. The Boolean expressions
will involve just two Boolean variables (let us say A and B) and your
truth tables will have all possible permutations of A and B.
* There will be questions on conditionals. You will either write
conditional statements given a set of criteria or you will
be given a conditional statements and a set of input values and
you should be able to state what the result or output of those
conditionals will be.
* There will be questions on while and for loops. You should know
the use of sentinel values and boolean flags. You also be familiar
with break and continue within a loop.
* You can be asked to draw patterns using nested loops.
* You are responsible for these built-in functions:
- abs (x)
- bool (x)
- chr (x)
- eval (expr)
- float (x)
- format ()
- input (prompt)
- int (x)
- len ()
- list ()
- max ()
- min ()
- ord (x)
- pow ()
- print ()
- range ()
- round (x, n)
- str (x)
- sum ()
- type (x)
* From the Math library you are responsible for
- ceil ()
- floor ()
- log (x, base)
- pow ()
- sqrt ()
- hypot ()
- math.pi
* From the Random Library you are responsible for
- randint ()
- randrange ()
- random ()
- uniform ()
- choice ()
- shuffle ()
- sample ()
* You will write short functions or use functions that we have
already written in class to solve problems. The user defined
functions that we have developed in class are:
- sum_digits (n)
- rev_num (n)
- is_palindromic (n)
- is_prime (n)
- sum_divisors (n)
* You will have to write a full length program that will involve
user input, computations involving operators and functions,
conditionals, loops, and output.
* Go through all the worked pieces of code in the book and then
do the exercises at the end of each chapter.
* Do the Logic-1 and Logic-2 problems from both the Python and
Java sections in CodingBat.
