Last active July 15, 2018 20:10
[Python - When to use yield instead of return in Python?] #Python #yield #tutorial #interview

The yield statement suspends function’s execution and sends a value back to caller, but retains enough state to enable function to resume where it is left off.

When resumed, the function continues execution immediately after the last yield run.

This allows its code to produce a series of values over time, rather them computing them at once and sending them back like a list.

[Python - How to write an empty function in Python – pass statement?] #Python #tutorial #interview #emptyfunction #passStatement

In C/C++ and Java, we can write empty function as following

// An empty function in C/C++/Java
void fun() {  }

In Python, if we write something like following in Python, it would produce compiler error.

# Incorrect empty function in Python
def fun():
