Hi Yusuf!

An argument is a piece of data which a function can take and work with. The arguments which a particular function can take are defined by the parameters (parameter variables) inside the braces after the function name. (A function can have as many parameters as you want, even zero.) In our case, the function should have one parameter, the variable called count, which determines how many times will we print our "Hi " message to the screen. When we use ("call") the function, we'll give an actual value to this variable. This actual data/value assigned to the parameter is the so-called argument. (Thus, the part in the challenge description "should take a single argument, count" should be understood as "should take a single argument, which will be assigned to a parameter variable named count".)

Also note: every line which belongs to the function (the "function body") should be indented - if a line is not indented, then it won't be part of the function definition.

As the challenge says, you can multiply a string by using the * operator, e.g. "Hi " * 2 evaluates to Hi Hi.

# this is the function definition, like a blueprint 
# the function has one parameter, the 'count' variable
# this means that the function can take one argument,
# and any value we're passing in as argument
# will be the new value of this count variable
def printer(count):
    print("Hi " * count)

# now we can use the above defined function like this:
# we're calling the function with a given argument (the integer 3)
# now the value of count will be 3 inside the function,
# so Python will print "Hi " three times
printer(3)  # --> this line will print 'Hi Hi Hi' to the console
