Local Variables versus Methods





# If a local variable exists with the same name as a method, 

# the local variable will be referenced 

# unless you put parentheses behind the method or use self.methodName.



def colors(arg1="blue", arg2="red")

    "#{arg1}, #{arg2}"

end



colors = 6

print colors



# The above outputs 6.
