14

Output to the user
15

for
A
Repeat a process for a set number of times
16

A
Repeaet while a condition is true
17

A
Do a loop untill a condition is true
18

Cast to string
19

A
Cast to integer
20
Q
INTEGER
A
Whole number
Eg: 1, 2, 3, 4
21
Q
REAL or FLOAT or DOUBLE
A
A number with a decimal point
Eg: 1.1, 1.2, 1.3, 1.4
22
Q
BOOLEAN
A
Either True or False
23
Q
CHARACTER
A
A single alphabetic or numeric character
Eg: ‘A’, ‘@’
24
Q
STRING
A
A sequence of one or more characters
25
LIST or ARRAY
A container that conrain more data
| Eg: ['eggs', 'are', 'good']
26
DICTIONARY
Key value pairs
| Eg: {'name': marc, 'age': 14}
27
Give some boolean operators
```
>
>=
<
<=
==
!=
```
28
100 > 10^2
False
29
n^2 == n*n
True
30
Pseudocode
Structurd english for descriving algorithms
31
Use of pseudocode
Allows a programmer to focus on the logic of the algorithm without being dristracted by syntax
32
Sequence
The statements are executed one by one, in the order they are written
33
Selection
The nest statement to be executed depends on whether the condition being tested is TRUE or FALSE
34
Switch/case
Used if there are several options to be tested
35
Assign a integer 5 to the variable x
x = 5
36
Assign an input for a person's username to a variable called y
y = input("What is your name? ")
37
Iteration
Repetition
38
Give examples of functions that use iteration
For
While
Do untill
39
Write a program that loops from 0 to 6 and prints out those numbers using iteration
for i in range(0, 7):
| print(i)
40
Write a program that keeps asking for a password if its incorrect
password = input("Enter password")
while password != "secret":
print("incorrect password")
password = input("Enter password")
41
Write a program that keeps asking for a password if its incorrect using a do untill loop
do:
password = input("Enter password")
until password == "secret"
print("correct password")
