How is an if else statement constructed in Python?
What is its purpose? - ....ANSWER...provides a way to
control what code executes based on the result of a
test expression
if <TestExpression>:
<block>
else:
<block>
How are compound mathematical expressions
evaluated in Python? - ....ANSWER...First perform
calculations within parentheses.
Next work left to right and perform all multiplication
and division.
,Finally, work left to right and perform all addition
and subtraction
What is the function of parentheses, (), in
programming expressions? - ....ANSWER...When we
are working with an expression, they group items
within that expressions. Items within parentheses
are evaluated first. For example:
(5 + 3) * 8 = 64 because we do the addition first, then
multiplication
5 + 3 * 8 = 29 because we do the multiplication first,
then the addition.
We also use parentheses in procedures to define the
inputs to that procedure, which is a very different
idea than when working within an expression..
< - ....ANSWER...less than
> - ....ANSWER...greater than
<= - ....ANSWER...less than or equal to
,>= - ....ANSWER...greater than or equal to
== - ....ANSWER...comparisons equality
How does the OR operator evaluate two operands? -
....ANSWER...If <Expression1> has a True value, the
result is True and <Expression2> is not evaluated (so
even if it would produce an error it does not matter).
If <Expression1> has a False value, the result of the
or is the value of <Expression2>.
How does the AND operator evaluate two operands?
- ....ANSWER...If <Expression1> has a False value, the
result is False and <Expression2> is not evaluated
(so even if it would produce an error it does not
matter). If <Expression1> has a True value, the result
of the and is the value of <Expression2>.
How are elements in a list indexed? -
....ANSWER...List elements are assigned an index
number starting with 0.
What is mutation? Do lists support mutation? -
....ANSWER...This is the ability to change the value of
something. Lists support mutation, allowing you to
, change the overall length as well as individual
elements within the list.
How is a for loop constructed in Python? What is its
purpose? - ....ANSWER...A for loop provides a way to
execute a block once for each element of a list. The
syntax is this:
for <Name> in <List>:
<Block>
How do you select a sub-sequence of a list with
Python? - ....ANSWER...You specify the index position
to begin the selection and the index position by
which to stop the selection. For example, the
following code would print red and yellow because
they are at position 0 and 1.The value of 2 tells us to
stop the selection at position 2, but not to include it.
myColors = ["red","yellow","blue","orange","green"]
print myColors[0:2]
What does the pop method do to a list in Python? -
....ANSWER...By default it removes the last element
from a list. It can also be used with an index number
