Flow Of Control

Question 1

Answer 1

Not, and, or, ==

2 possible Boolean values, True or False

Question 2

Logical equivalence

P == q

Answer 2

==

Will be True only when both have the same truth value. (Both True ir both false)

Question 3

Logical “and”

P and q

Answer 3

True only when both are True

P and q

True only when p is true and q is true.

Question 4

Logical “or”

Answer 4

True only when either one is True

Question 5

!= means what?

Answer 5

Not equal

Question 6

Logical negation

Answer 6

Not p

True when p is False, and False when p is True

Question 7

If statements

Answer 7

Always begins with the keyword if.

Followed by Boolean expression called the if-condition

Followed by a colon (:)

Question 8

If-statement header

Answer 8

Everything from the if statement to the :

Before_block 
If cond:
     True_block
Else:
    False_block
After_block

Question 9

If/elif - statements

Answer 9

A generalized if-statement with more than one condition.

Elif = else if

If ..... :
     If_block
Elif ... :
    Elif_block
Else:
    Else_block

Question 10

For-loops

Answer 10

A given block of code repeated some specified number of times.

For (loop variable) (keyword) (range):

For i in range(10):

Question 11

While-loops

Answer 11

While-loop header

While (while loop condition)
The condition is boolean and always returns a True or False

If condition true, then executes while-loop body, if false executes what is after body.

First line is initialization statement ue i = 0
Incremental, i = i + 1

Question 12

While-loop flow

Answer 12

Initializer_block
While cond:
Body_block
After_block

Question 13

How do you exit a loop?

Answer 13

Break statement

Break # causes to jump out of the loop

Question 14

Answer 14

Boolean logic is all about manipulating so-called truth values.

Written True or False
