CC3 MIDTERM REVIEWER

Selection Structure

Provides a choice between two alternatives

single alternative selection structure

is a type of decision-making control structure in programming.

Iteration

Most useful and powerful structure and Allows the repetition of instructions or statements in the loop body

for loop

is generally used for traversing and manipulating arrays

while loop

Loops that are dependent on a sentinel value (or indicator) are better coded using a ________

accumulator

is a variable that “sums up” or accumulates values

sentinel value

It is a special type of value that allows a different number of inputs by the user each time.

Break Statement

Force immediate termination of a loop, bypassing the conditional expression and any remaining code in the body of the loop.

else keyword

The ________ in a for loop specifies a block of code to be executed when the loop is finished:

continue statement

cause control to be transferred directly to the conditional expression that controls the loop.

pass statement

is a null operation; nothing happens when it executes.

Exceptions

Events or errors that disrupt the normal flow of execution of a program. 

Checked Exception 

they are subject to the Catch or Specify Requirement. Otherwise, the program code will not compile, are errors that the program can deal with. 

Errors

are generally beyond the control of the program.

Runtime Exception

are not subject to the Catch or Specify Requirement and are, also, unchecked exceptions. These exceptions are the result of programming flaws

try and except block

is used to catch and handle exceptions. Python executes code following the try statement as a “normal” part of the program.

try block

lets you test a block of code for errors. 

Except block

will be executed if the try block raises an error. 

finally block

if specified, will be executed regardless if the try block raises an error or not. 

Raised Keyword 

Use to execute an exception depending on the condition 

Matlab

is not considered a real programming language

SciPy

Numerical integration and optimization.

NumPy

Provides N-dimensional array objects, linear algebra, Fourier transforms.

Jupyter

Changes how programming is done in Python.

Requests library:

Simplifies HTTP operations, supports verbs like GET, POST, PUT, DELETE.

MACHINE LEARNING

Effective and adaptive tool to learn from experience and it originates from Computer Science and Statistics.

Scikit-Learn

Well-known Machine Learning tool built on top of other
Python scientific tools like NumPy, SciPy, and Matplotlib

OBJECT RELATIONAL MAPPING (ORM)

Connects object-oriented programming to relational databases.
