Strings - 3.2.3

# Are an abstraction since it allows you to perform operations on multiple words and/or letters without seperating them individually
# Allows letters to be represented using language rather than numbers
firstName = "John"
lastName = "Doe"
laugh = "Ha"
fruit = "Watermelon"
fruitWithSpace = "   Watermelon   "

# Concatenation
print("Concatenation:")
print("First name and Last Name:", firstName + " " + lastName) #abstracts by allowing dynamic manipulation of strings
print("-"*50)

# Repetition
print("Repetition:")
print(laugh * 4) #abstracts having to use a loop to repeat the string
print("-"*50)

# Indexing String
print("Indexing:")
# 0 based indexing system
print(fruit[0:5]) #abstracts having to use a loop to iterate then manually obtain the first 4 letters
print("-"*50)

# Length of String
print("Length of String:")
print(len(firstName)) #abstracts having to count the letters manually or using more steps
print("-"*50)

# Change Letter Format
# prevents having to loops to manually change letter format based on condition
# otherwise would require checking through ASCII or other methods
print("Changing Letter Format:")
print(firstName.upper())
print(firstName.title())
print("-"*50)

# Strip
# Abstraction as a condition and loop is not required to identify spaces and remove them
print("Removing whitespace:")
print(fruitWithSpace.strip())
