Strings, Dictionaries and Sets - CSP5110 - Free Assignment Solution

In this assignment task, we will revise Python concepts by experimenting with string manipulations and dictionary operations. Our experts will guide you through the process, ensuring you understand each step and how to apply these techniques effectively.

Task 1 – Concept Revision in the Python Shell 

Let’s revise the concepts from this module by typing some simple statements into the Python Shell. Feel free to deviate from the workshop and experiment! 

1. pun = 'Eating a clock is very time consuming!!!'
2. pun[23:]
3. pun = pun.rstrip('!')  
4. pun.count('i')
5. punWords = pun.lower().split() These statements manipulate a string in various ways. 
6.  scores = {'Mary': [22, 23, 36],  'Fred': [20, 21, 29]}  This creates a dictionary with two items.  The items have keys of “Mary” and “Fred”, and the values are both lists containing three integers (test scores out of 25, 25 and 50). 
7. scores['Mary'] 8. scores['Fred'][1] 

These statements demonstrate how to refer to an item in a dictionary via its key.   Since the value is a list, you can then refer to an item in the list via its index. 

Task 2 – Password Checker 

Below is a copy of the password rules from ECU’s password changing page: 

• A maximum of 16 characters 
• A minimum of 8 characters 
• A minimum of 1 upper case character 
• A minimum of 1 lower case character 
• A minimum of 1 number 
• A minimum of 1 special character: '~!#$%^*()_+-={}|[]\:<>?,./ 

  Write the code to implement this pseudocode in the “checkPassword()” function.

Task 1 Solution:

pun = 'Eating a clock is very time consuming!!!'
print(pun[23:])
pun = pun.rstrip('!')
print(pun)
print(pun.count('i'))
punWords = pun.lower().split()  
print(punWords)

scores = {'Mary': [22, 23, 36], 'Fred': [20, 21, 29]}
print(scores)
print(scores['Mary'])
print(scores['Fred'][1])
scoreKeys = scores.keys()
print(scoreKeys)
scores['Jane'] = [21, 24, 30]
scores['Fred'][2] = 39
print(scores)
#HDs = [name for name in scores if sum(scores[name]) >= 80]
#print(HDs)

set1 = {4, 2, 6, 3, 6, 2, 7}
set2 = set([9, 1, 0, 2, 4, 1, 4, 6])
print(set1)
print(set2)

print(set1 | set2)
print(set1 & set2)

 

Task 2 Solution:

def checkPassword(pword):
    
    shortEnough = False
    longEnough = False
    hasUpper = False
    hasLower = False
    hasNumber = False
    hasSpecial = False
    specialChars = '\'~!#$%^*()_+-={}|[]\\:<>?,./'
    
    if len(pword) <= 16:
        shortEnough = True
    if len(pword) >= 8:
        longEnough = True
    for i in pword:
        if i.isupper():
            hasUpper = True
        if i.islower():
            hasLower = True
        if i.isdigit():
            hasNumber = True
        if i in specialChars:
            hasSpecial = True
    
    
    if shortEnough == True and longEnough == True and hasUpper ==True and hasLower ==True and hasNumber == True and hasSpecial==True:
        return True
    return False

password = input('Enter your password: ')
if checkPassword(password):
    print('Your password is valid.')
else:
    print('Your password is not valid.')
