The module can contain functions, as already described, but also variables of all types (arrays, dictionaries, objects etc): Example Save this code in the filemymodule.py person1 = { "name":"John", "age":36, "country":"Norway"

This module provides alternatives to built-in container data types such as list, tuple and dict. namedtuple() function This function is a factory function that returns object of a tuple subclass with named fields. Any valid Python identifier may be used for a field name except for names starti...
The collections module contains high-performance implementations of a few useful container types, abstract base classes for various kinds of containers, and a utility function for creating name-tuple objects. This module implements specialized container datatypes providing alternatives to Python’s general ...
Types of Cryptography There are three widely used types of cryptography: Table: Types of Cryptography Python Modules for Cryptography Modules are files that contain Python statements and definitions for functions, classes, and variables that can be used in your program. It essentially makes the code...

Module - types 1. User-Defined Function Checker Write a Python program to check if a function is a user-defined function or not. Use types.FunctionType, types.LambdaType() Click me to see the sample solution 2. User-Defined Method Checker ...
With Python 3, it is possible toindicatethe expected types for arguments/return values, and we’ll do just that later in this chapter. However, indicating the types expected does not “magically” switch on type checking, as Pythonneverchecks the types of the arguments or any return values....
with the failure. This exception clause is too broad for normal use as it will catch and hide all errors that could happen in the try block. When you create your module you should only except error types that you anticipate to avoid hiding stack traces of unexpected errors from your logs....
