This blog post continues on from my previous Programming 102 tasks/challenges.
2.5 Strings As Lists
Task: “On scoreboards, sports teams are sometimes referred to using a contraction of their name, often the first three letters. Can you write some code in order to create a new list, teams_short, containing three-letter contractions of each of the teams in the list, in the same order as they appear in teams?“.
My Solution:
teams = [“WOLVES”, “OWLS”, “PANTHERS”, “BEARS”, “DRAGONS”]
teams_short = []
for team in teams:
team_name = team[:3]
teams_short.append(team_name)
print(teams_short)

2.8 Implement Count Function
Task: “Can you add a generic count function to this program so that it prints out the number of learners that scored top marks?“.
import random
def top_scorers(score_to_count,list_to_use):
score_number = 0
for score in list_to_use:
if score == score_to_count:
score_number +=1
return (print(“{0} learners got top marks”.format(score_number)))
scores = []
for x in range (0, 30):
scores.append(random.randint(0, 10))
print(scores)
top_scorers(10, scores) # Count function called here
Python Count Function
2.9 Time To Share Your Code
Task: “In the previous challenge you created a function to count the number of occurrences of a number in a list. Then you extended your program to count strings or letters, or used it to find the number of scores in a range.”
My solution:
import random
def list_item_counter(item_to_count,list_to_use):
occurrences= 0
for item in list_to_use:
if item == item_to_count:
occurrences +=1
return (print(“{0} appeared {1} times in the list”.format(item_to_count, occurrences)))
list_to_use = “Harry Potter”
list_item_counter(“t”, list_to_use) # Count function called here

2.11 Mean, Max and Min
Task: “Choose one of the following functions: mean (average), minimum, or maximum. Think of a real-world scenario where you need to work with data and find the average, minimum or maximum of a list of values. This could be using data that you work with in school, or for a hobby or other interest”.
I decided to use Python’s built in “min” and “max” functions and then created a function to look for an average wage. There are few different types of averages (see https://www.bbc.com/bitesize/articles/z99jpbk). I looked a fictional wages to see the minimum, maximum and average wage.
