Function with outputs

def my_function():
  result = 3 * 2 
  return result #output is the result

title()
Return a version of the string where each word is titlecased.More specifically, words start with uppercased characters and all remaining cased characters have lower case.

def format_name(f_name, l_name):
  f_f_name = f_name.title()
  f_l_name = l_name.title()
  return f"{f_f_name} {f_l_name}"

print(format_name("awESOMeE", "kIM"))

#output
Awesomee Kim

return tells the compiter that this is the end of the function.

def format_name(f_name, l_name):
  """Take a first and last name and format it 
  to return the title case version of the name."""
  #Docstrings
  """Docstrings are basically a way for us
  to create little bits of documentation
  as we're coding along in our functions
  or in our other blocks of code."""
  if f_name == "" or l_name == "":
    return "You didn't provide valid inputs."
  formated_f_name = f_name.title()
  formated_l_name = l_name.title()
  return f"Result: {formated_f_name} {formated_l_name}"

#Storing output in a variable
print(format_name(input("What is your first name? "), input("What is your last name? ")))
