• Introduction to Python Programming Language

• Introduction and Features of Google Colab

• Opening, saving and sharing Colab Notebook

• Basic Python syntax and comments

• Documenting Python code using Markdown syntax

1. Colab implicitly uses Google Drive for storing your notebooks, 

2. Login into your Google Drive account 

3. Go to the Google Colab website: https://colab.research.google.com/.

4. Click the File menu and select New Notebook.

5. You can choose to create a blank notebook or a notebook with a template.

6. Once you have created a notebook, you can start writing code.

7. Rename the notebook with the suitable name 

8. Notebook is saved as .ipynb format

9. In the Code Cell of the Google Colab, Type the following code, 

print("Python Programming for Engineers")

10. Click on the Run Cell Icon to Run the Line of code, within microseconds code gets executed and the output is displayed in the Output Cell. 

• Python uses indentation to group statements together. All statements within a block of code must be indented at the same level.

• Python uses keywords to define different parts of a program, such as functions, loops, and conditional statements.

• Python uses variables to store data. Variables are declared using the = operator.

• Python uses operators to perform operations on data. Some common operators include +, -, *, and /.

# Code for Arithemetic Operations of Numbers 

num1 = 20 

num2 = 5 

# Addition 

sum = num1 + num2 

print(sum) 

# Subtraction 

difference = num1 - num2 

print(difference)

# Multiplication 

product = num1 * num2 

print(product)

# Division 

quotient = num1 / num2 

print(quotient) 

# Exponentiation power = num1 ** num2 

print(power) 

# Modulos 

remainder = num1 % num2 

print(remainder) 

• Comments are used to make code more readable and understandable. They are ignored by the Python interpreter, but they can be helpful for explaining what your code is doing.

• Single-line comments start with a hash (#) and extend to the end of the line. 

• Multi-line comments start with three double quotes (""") and end with three double quotes (""").

• Code Cell supports Python syntax, and we can use Python comments to describe the code. 

• Colaboratory also supports simple text based documentation using Text Cells, which supports Markdown syntax and LaTex - a language for mathematical representations using which we can document mathematical equations.
