Programming 102 Week 2 Tasks (Python)

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

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.

102_2_11_mean_max_min_geektechstuff — Python Min, Max and an Average function

wage = [500,550,500,525,800,650,600,575,650]

min_wage = min(wage)

max_wage = max(wage)

def average(list):

items_count = 0

total = 0

for item inlist:

items_count = items_count + 1

total = total + item

avg = total / items_count

avg = int(avg)

return(print(avg))

print(min_wage)

print(max_wage)

average(wage)
