Problem: Write and invoke a function, nameOrganizer, that takes in your first name and last name, outputting your full name.

This is simple string concatenation! Adding two strings together results in a combination.

Solutions:

• Show Solution
  def nameOrganizer(firstName, lastName):
   return firstName + ' ' + lastName
  
  fullName = nameOrganizer('Elias', 'Xu')
  # Expecting Elias Xu
  print(fullName)
• Show Solution
  def nameOrganizer(lastName, firstName):
   fullName = firstName + ' ' + lastName
   return fullName
  
  # Expecting Daniel Elliot
  print(nameOrganizer('Elliot', 'Daniel'))
• Show Solution
  No Third Solution

Problem: Write a function and its invocation that divides two numbers and prints the difference between its quotient and remainder

The floor division operator (//) performs division and rounds the quotient down to the nearest whole number. The modulus operator (%) performs division and returns the remainder

Solutions:

• Show Solution
  def quotientMinusRemainder(dividend, divisor):
   return dividend // divisor - dividend % divisor)
  
  # Expecting -1
  quotientMinusRemainder(13, 5)
• Show Solution
  def quotientMinusRemainder(dividend, divisor):
   answer = dividend // divisor
   remainder = dividend % divisor
   return answer - remainder
  
  # Expecting -1
  print(quotientMinusRemainder(13, 5))

Problem: Write a faulty Python program that defines variable foo = 12 and invokes print(foo). However, the print invocation should result in an error, stating that foo is undefined

If you constrain a variable to its local scope, it cannot be accessed outside of said scope

Solutions:

• Show Solution
  def foonction():
   foo = 12
   return foo
  
  # Expecting ERROR
  print(foo)
• Show Solution
  #Expecting ERROR
  print(foo)
  
  foo = 12
• Show Solution
  No Third Solution
