wrong number of arguments (given 0, expected 1) 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: Expected 1 arguments, but got 0.

(click)="myFunc(i)" //Index needs to be passed when button is inside *ngFor
