Programming Flashcards
Write a program that prints fizz if the number is a multiple of 3, buzz if its a multiple of 5 and both if its a mult of 3 and 5
for counter in range (1,101):
if counter%3 == 0 and counter%5 == 0:
print(‘FizzBuzz’)
if counter%3 == 0:
print(“Fizz”)
if counter % 5 == 0:
print(“Buzz”)
else:
print(counter)
What is a data type?
It is a way of classifying a value so the programming language knows how to interpret the value
What is a count controlled loop?
Used when the number of iterations to occur is already known
We know how many times we want to execute the loop
What is a variable?
A value which is stored inside the computers memory.
What is a for loop? Give example
A block of code that repeats for a limited amount of times. Stops when condition is proven true.
E.g, numbers = [1,2,3,4,9,16]
B=[]
For i in numbers:
B.append(i**2)
Print(b)
What is a while loop give example?
A while loop is a block of code which repeats until the condition is proven false.
X = 5
While x < 5:
X = x+1
Print(“John”)
Or
Num = 1
While True:
Print (“John”)
Num = num+1
If num == 5:
Break
Example of pseudocode in python
Endif
Endwhile
Rule of pseudocode
If the code is pseudocode you dont put a data type before any value because it doesnt need it
Code asks user for phone number and length needs to be over 6 letters and under 12
Number=int(input(“What is your phone number”))
If len(number) == 0:
Print(“Invalid”)
Elif len(number) >6 AND <12:
Print(“Thank you”)
Endif
What is a variable?
A value stored within a reserved memory location in the computer
Difference between a variable and a constant?
A constant cant change at all whilst a variable can
What is an array?
A static structure which constains items of the same data type. A series of memory locations which contains a single item of data.. ordered and fixed in size
What is a list?
A dynamic structure which can contain elements of different types. Ordered and not fixed in size
What is a 2 dimensional array?
A collection of elements arranged in a table like structure wth rows and columns
An array inside an array
What does def mean?
Short for define it defines the function
Whats iterative testing?
Testing that is ongoing throughout it the development process whilst the code is being written.
What is final testing?
When the development of the code is fine it is tested
Wat is a syntax error?
An error where the code doesn’t meet the rules of the programming language
