Lists, Subroutines and Sequence in Pseudocode - Python

What will the following code output? Enter your answer.

NumberList = [ 1, 5, 7, 4, 5, 1, 9, 9 ] 

print(NumberList[3])

(a)  

Answer explanation

In programming the index position always starts at 0.

In other words, the first item in a list is in index position 0.

What will the following code output?

NumberList = [ 1, 5, 7, 4, 5, 1, 9, 9 ] 

Length = len(NumberList)

print(Length)

• 7

• 8

• 9

• 6

What is the maximum number this program can randomly output?

import random

print(random.randrange(0, 1000))

• 10000

• 1000

• 999

• 1001

Answer explanation

When checking range values, never include the end/stop or last value.

This is because index position starts at 0 not 1 so the last is always missed.

(0, 100) - this actually means 0 to 99.

This type of subroutine passes and returns values.

What am I?

• Procedure

• Function

Enter the exact code missing in LINE 3 to call this procedure

(a)  

Answer explanation

If you do not call your procedure name, then it will not run.

You can call your procedure name in other subroutines, not just the main program.

If the input value for variable toSquare is 5, what result will this function return?

Answer explanation

We are PASSING the data stored in variable toSquare to parameter x of square function and then returning the result of y into global variable result.

Functions allow us to re-use our code.

In pseudocode which symbol can we use to replace assignment =
