MODULES, COMMENTS, AND PIP IN PYTHON
Let's write our first Python program by creating a python file (first.py) and let us paste the following code into the above program.
 |
| Python Module |
print("Hello World")
When we execute this program, we see the output Hello World in the Output Screen.
MODULES
A Module is a file that basically contains the code written by others, but it can be imported and used in our own programs
PIP
Pip is the package manager for python which is used to install the modules in our program/system. Eg. If you have to import a flask or Django module in your program first you have to install it using
pip install flask
pip install pandas
TYPES OF MODULES
There are two types of modules in python.
- Built-in Modules - Pre-installed in python
- External Modules - Have to install using pip
Example of built-in modules is os, ABC, etc.
Example of External modules is TensorFlow, flask, etc.
COMMENTS
Comments are used to write something in the program which the programmer doesn't want to execute.
Types of Comments
There are two types of Comments in Python:
- Single Line Comment - Written using '#'
- Multi-Line Comment - Written using 'comment'
