Big IF


#1

Make sure that the_flying_circus() returns True

def the_flying_circus():
if 2 != -2: # Start coding here!
# Don't forget to indent
# the code inside this block!
elif 0 == 10 % 2:

    # Keep going here.
    # You'll want to add the else statement, too!
    else:
   return "Nothing"

Why does this not work. Have been trying for over an hour now...

@boardblaster48025,

def the_flying_circus():
    #4 space indentation as start of the FUNCTION-BODY
    if 2 != -2: # Start coding here!
        # 4 space indentation as indication of the IF code-block
        # as the CONDITION two not less than minus two ==>gives a Boolean True
        # the code here is executed
        print "The condition 2 != -2 is a Boolean True"
        # if you use a =return= statement you will EXIT the function
        return True
        # this is the end of the IF codeblock
    elif 0 == 10 % 2:
        # this indentation is the ELIF code-block indicator
        # The CONDITION zero equals ten modulo 2 results in a Boolean True
        # but as the IF condition was a TRUE this code-block will NEVER be reached !!!
        return True
        # this is the END of the ELIF code-block
        # You'll want to add the else statement, too!
    else:
       return "Nothing"

@boardblaster48025,

the FUNCTION talk

def myFunc( param1, param2):
    # Begin of =myFunc= FUNCTION-BODY
    # this =myFunc= function- has 2 PARAMETERS param1 and param2
    # param1 and param2 PARAMETERS are used 
    # as -local- VARIABLES throughout the =myFunc= FUNCTION-BODY
    print( param1 + " and " + param2 )
    #End of =myFunc= FUNCTION-BODY

If you want to call/execute the myFunc function
you will have to add a pair of parentheses to myFunc
like
myFunc()
As the myFunc function was defined
as having 2 parameters
you have to provide 2 arguments
in our case 2 string VALUES "Alena" and "Lauren"
like
myFunc("Alena","Lauren")

some quotes from the outer-world:

**argument is the value/variable/reference being passed in,
parameter is the receiving variable used within the function/block**

OR

**"parameters" are called "formal parameters",
while "arguments" are called "actual parameters".**

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
++++ function with 1 parameter using return-statement

def myFunction( param1 ):
    # //Begin of =myFunction= FUNCTION-BODY
    # //=myFunction= function has 1 PARAMETER param1
    # //this param1 PARAMETER is used as a -local- VARIABLE
    # //throughout the =myFunction= FUNCTION-BODY
    return param1;
    # //End of FUNCTION-BODY

You have defined a myFunction function
which takes 1 parameter param1
this param1 parameter is used
as a variable throughout the =myFunction= FUNCTION-BODY.

If you want to call/execute this myFunction function
and this myFunction function was defined
as having 1 parameter param1
you will have to provide 1 argument
in our case a "number VALUE" 4
myFunction( 4 )

some quotes from the outer-world:

**argument is the value/variable/reference being passed in,
parameter is the receiving variable used within the function/block**

OR

**"parameters" are called "formal parameters",
while "arguments" are called "actual parameters".**

Thanks so much for this, I was totally lost until you stepped through it line by line!
