Programmer's guide to python

6.5 pass statement

>It is used to define a function/method/class with an empty body without raising an error, so that we can come back later to implement the function.
>pass can be used in empty functions & classes definitions and also in empty loops. pass isn't like continue, if there is some code after pass it is executed.

## Example 1: Empty function body
def my_fun():
  pass


## Example 2: Empty loops
for a in range(10):
  pass
# here pass will make sure the for loop doesn't raise a Exception


## Example 3: Another example
for a in range(2):
  pass
  print("hello")  # hello \
                  # hello
# pass doesn't do anything else, the print statement is executed
