Getting Started :computer:

Time needed: 30-40 minutes

1. Create a new Colab Notebook
2. Name your notebook: C1_Intro_to_Python & C2_Jupyter_Notebook.ipynb
3. Save your work after completing each section

:bulb: Remember to run each code cell by pressing Shift + Enter or clicking the play button!

Question One: Working with Text Cells :emoji:️

Time estimate: 10 minutes

Step-by-step Instructions:

1. Create a text cell and add a heading:
   • Click the + Text button
   • Type # Basic to create a heading 1
   • Press Shift + Enter to render the cell
2. Create another text cell for a subheading:
   • Click + Text again
   • Type ## Question 1 to create a heading 2
   • Press Shift + Enter to render
3. Create a text cell with formatted content:
   • Add a new text cell
   • Copy the text from the image below
   • Add a hyperlink to the word "here" using this format: [here](https://www.telebort.com/) tip Markdown Quick Reference:

• # Text = Heading 1
• ## Text = Heading 2
• [link text](URL) = Hyperlink
• **text** = Bold text

Question 2: Basic Python Programming :computer:

Time estimate: 10 minutes

Step-by-step Instructions:

1. Create a text cell for the section heading:

   • Add a new text cell
   • Type ## Question 2
   • Press Shift + Enter

2. Create your first code cell:

   • Click + Code button
   • Type the following code:
   python

   #print Welcome to Telebort
   print("Welcome to Telebort")
   

   • Run the cell (Shift + Enter)
   • Expected output:
   output

   Welcome to Telebort
   

3. Create a second code cell to print multiple lines:

   • Add another code cell
   • Type this code (use your own name and age!):
   python

   #print name and age
   print("My name is Yong Sheng\nI am 15 years old")
   

   • Run the cell
   • Expected output:
   output

   My name is Yong Sheng
   I am 15 years old
   

:bulb: Remember: The \n creates a new line in your output!

Advanced: Interactive Programming :computer:

Time estimate: 10-15 minutes

Step-by-step Instructions:

1. Create a section heading:

   • Add a text cell
   • Type # Advanced
   • Press Shift + Enter

2. Create an interactive program that asks for user input:

   • Add a code cell
   • Type this code to collect user information:
   python

   name = input("What is your name?")
   age = input("What is your age?")
   school = input("What is your school?")
   

   • Run the cell and answer each prompt
   • Example interaction:
   output

   What is your name?Yong Sheng  # user types their answer
   What is your age?15  # user types their answer
   What is your school?Telebort  # user types their answer
   

3. Display the collected information:

   • Create a new code cell
   • Type this code to show the results:
   python

   print("What is your name?" + name)
   print("What is your age?" + age)
   print("What is your school?" + school)
   print("Hi, " + name + ". You are " + age + " years old from " + school)
   

   • Run the cell to see your personalized output:
   output

   What is your name?Yong Sheng
   What is your age?15
   What is your school?Telebort
   Hi, Yong Sheng. You are 15 years old from Telebort
   

tip Pro tip: Make sure to run the input cell first before running the print cell, or you'll get an error!

Troubleshooting Guide :hammer_and_wrench:

Common Issues and Solutions:

1. "NameError: name 'variable' is not defined"

   • Make sure you've run the cell that creates the variable first
   • Check for typos in variable names

2. Text not formatting in text cells

   • Remember to press Shift + Enter to render markdown
   • Check that you're in a text cell, not a code cell

3. Input() not working

   • Click in the input box that appears below the code
   • Type your answer and press Enter
