proper way to define a function in python code example
Example 1: how to define function in python
def example(): #This defines it
print("Example.") #This is the defined commands
example() #And this is the commands being run
Example 2: how to make a function in python
def test_function(argument1,argument2,argument3) :
# Do something with the code, and the arguments.
print(argument1)
print(argument2)
print(argument3)
# Calling the function.
test_function('Hello','World','!')
# Output
'''
Hello
World
!
'''
Example 3: python functions
# Python Functions
def a_function(): #def FUNCTIONNAMEHERE(): Function content
print("Hello World!")
return 0
def answerValid(prompt, correct_answers, invalid): # Functions can also have parameters, or variables that can be used only in tha function
while True:
user = input(prompt)
if user in correct_answers:
break
return user # Example Function
else:
print(invalid)
a_function() # To call a function; Prints 'Hello World!'
# But if this is done:
function_called = a_function() # function_called would contain a 0, because the function returns 0
answer = answerValid("What is 8 * 8?", [64], "Invalid Option")
print(answer) # Prints 64, because that is the only possible answer
Example 4: how to add a fuction in python
#How to define a function
def new_function(): #Creates a new function
print("Function is here!") #Here we write what we want our function to do
#How to call a funtion
new_function() #Just type in the fuction's name and add brackets after it!
Example 5: how to define a function in python
variable = "Hello, world!" # variable = string("Hello, world!")
#A simply function :
def Functiontest(): #define a function
print("Hello, world!")
print(variable)
#Function with components :
def Functiontestwithcomponent(arg1, arg2): # Define a function with two arguments, arg1 and arg2.
if arg1 == True: # Arguments can have any name, like variables.
print(arg2)
#Call a function :
Functiontest() #Start Function.
#Call a function with two components :
Functiontestwithcomponent(True, "Hello, function!") #Start Function and precise two arguments :
Example 6: functions in python
#Functions
#Functions are followed by the 'def' keyword
#Name your function
def myfunc():
a = 'This is a func'
#Calling the function
myfunc()
print(myfunc())
