def greetings():
print("Hello World")
greetings()
Output:

Passing information to a function:
def greetings(myGuest):
print("Hello, " + myGuest + "!")
greet_user('Programming Clue')
Output:

Passing multiples arguments:
def favTeam(teamA, teamB):
print("\nMy favorite team is " + teamA + ".")
print("But I also like " + teamB + ".")
describe_pet('Real Madrid', 'FC Barcelona')
Output:
My favorite team is Real Madrid.

and re-use the function again
Use functions to return a value:
def getMyFavTeam(teamA, teamB):
myTeams = teamA + ' ' + teamB
return myTeams
soccer = getMyFavTeam('Real Madrid', 'Betis')
print(soccer)
Output:
Real Madrid Betis
Using a function-while loop
def fullName(firstName, lastName):
fullName = firstName + ' ' + lastName
return fullName
while True:
print("\nPlease tell me your name:")
print("(enter 'q' at any time to quit)")
firstName = input("First name: ")
if firstName == 'q':
break;
lastName = input("Last name: ")
if lastName == 'q':
break;
fName = fullName(firstName, lastName)
print("\nHello, " + fName + "!")
Output:
Hello, Peter Roman!
Please tell me your name:
(enter 'q' at any time to quit)
First name:
Passing a list as argument:
def students(names): for i in names: greetings = "Hello, " + i + "!" print(greetings)
classAttendance = ['Pippen', 'Jordan', 'Bryant']students(classAttendance)
classAttendance = ['Pippen', 'Jordan', 'Bryant']students(classAttendance)
