too many positional arguments 0 expected but 1 found code example

Example 1: 1 positional arguments expected but 2 were given

#Happens when a function expects only 1 value to be passed through it
#But multiple are passed through

class thing(object):
	def __init__(self):
    	pass
       
    def function(self)
		print("hello")

thingy = thing()
thingy.bind("<KeyPress>", thingy.function)

#You don't expect above to pass two values through, however it passes an event
#and self which is why it will give a positional argument error

Example 2: flutter too many positional arguments 0 expected but 1 found

Notification notif =
  Notification(description: u["description"], nom_ligne: u["nom_ligne"], created_at: u["created_at"]);

Example 3: flutter too many positional arguments 0 expected but 1 found

const Notification(this.description, this.nom_ligne, this.created_at);
