Please help!

Hi All...

Still getting used to writing my own functions

Please help me with this code...what am I doing wrong???

As I understand functions, you need to start with:

def "insert function name"()

My count is = 10

then print ("hi" * count or 10).

Then I need to call it again printer()...

thanks!:)

printer.py 
def printer():  
    count = 10 
    print("hi"*count)
    printer()

The way this function would work, you would print 'hihihihihihihihihihi' every time you called printer(). What if I wanted to print 'hi' twenty times? I couldn't use this same function.

Hi Greg, your almost there, just two issues.

1. The printer function should take one argument count so make sure to include that in the definition too. Since this is passed into the function, you shouldn't declare a local variable count, so remove that.

2. You don't need to call the printer function again.

def printer(count):  
    print("hi" * count)

Ok Starting to understand this better...

So def printer(This is kind of like giving a variable a name): print("hi" * count) --->> This "connects" the number of hi's in the print command to the value in count IN the () of def printer.

Hope im understanding this correctly:) Thanks!

Greg,

I think you are getting it!

Define a function named printer. When you call the printer function you know you will pass in a number so your function can print 'hi' as many times as that number is. For that reason you put in an argument that you name count. Now you have a function you can use the same function multiple times for different reasons.

ten = 10
one = 1

def printer(count):
    print('hi ' * count)  # notice the space after 'hi_'

printer(ten)  # this will print 'hi hi hi hi hi hi hi hi hi hi '
printer(20)  # this will print 'hi hi hi hi hi hi hi hi hi hi hi hi hi hi hi hi hi hi hi hi '
printer(one)  # this will print 'hi '

This is the beauty of functions. Making your life easier and not having to repeat the same code multiple times. Can you take this small function to another level? What if I wanted to input a string of my choosing into the printer function, how would you do that?

Hint, you will need to replace 'hi ' with something else.
