What is the only main difference between built-in functions and modules in python ?

Question

Explain the main difference between built-in functions and modules in python.Why these modules are stored in specific packages and libraries ?

Answer 1

Python Function :
A function is a block of organized, reusable code that is used to perform a single, related action. Functions provide better modularity for your application and a high degree of code reusing.

Python gives you many built-in functions like print(), etc. but you can also create your own functions. These functions are called user-defined functions.

# Function definition is here
def printme( str ):
"This prints a passed string into this function"
print str
return;

# Now you can call printme function
printme("Call user defined function")
printme("Again Call user defined function")
Output :

Call user defined function
Again Call user defined function

Python Module :
A module allows you to logically organize your Python code. Grouping related code into a module makes the code easier to understand and use. A module is a Python object with arbitrarily named attributes that you can bind and reference.

Simply, a module is a file consisting of Python code. A module can define functions, classes and variables. A module can also include runnable code.

Here's an example of a simple module that define in support.py

def print_func( par ):
print "Hello : ", par
return
For example, to import the module support.py, you need to put the following command at the top of the script −

# Import module support
import support

# Now you can call defined function that module as follows
support.print_func("Kamal Swami")
Output :

Hello :Kamal Swami

Answer 2

A module is group of statements that exist within a program for the purpose of performing a specific task.
A function is a type of module that returns a value back to the program that called it.
