Difference between Yield and Return in Python with python, tutorial, tkinter, button, overview, entry, checkbutton, canvas, frame, environment set-up, first python program, operators, etc.
The yield statement converts a standard Python function into a generator, and users can use the return statement to end the execution and then return the output to the caller statement. This article will discuss a brief difference between generator & yield and return function in Python....
The function only runs when the next() function is called on the generator object. When the next() function is called, the function runs until it encounters a yield statement. The value after yield is returned to the caller, and the state of the function is saved. The next time next()...

&的作用是告诉解释器,现在传入的不是正常的参数,而是一个代码块。这个传入的代码块在方法内通过yield进行调用。这里可以做个演示: ``` class Array def my_each i = 0 while i < self.size end self end end [1,2,3].my_each { |num| print “#{num}!” } 1! 2! 3! => [1,2,3] ``` ...
