Python Level 1: Introduction & Basic Syntax

Goal of this Level

You will learn to:

• Install Python and set up an editor
• >Useprint() to display output
• Useinput() to get user input
• Write comments
• Finally, create a small program that greets you by name and asks your age

Step 1: Install Python

Go to the official Python website: https://www.python.org/downloads

Download the latest version and, on Windows, check "Add Python to PATH".

Check installation :

python --version

Step 2: Set up an Editor

• Download Visual Studio Code: https://code.visualstudio.com/
• Install the Python extension
• New project: File → New → Save as programm.py

Step 3: print() – Display Text

print("Hello World")
print(5 + 3)

Explanation:

• Text in quotes → displayed exactly as written
• Numbers or variables → Python calculates or shows the value
• print() lets you display values to check what’s happening

Step 4: input() – User Input

name = input("What is your name?")
print("Hello,", name)

Explanation:

• input() shows a message and waits for the user to type something
• The input is stored in a variable, here name
• print() can then display the input or process it further

Step 5: Writing Comments

# Single-line comment
'''
Multi-line
comment
'''

Explanation:

• Comments explain the code and help you or others understand it later
• Python ignores comments; they don’t affect the program
• Single-line comments start with #
• Multi-line comments are enclosed in ''' gesetzt

Practice Example

name = input("What is your name?")
alter = int(input("How old are you?"))
print("Hello,", name + "!")
print("You are", alter, "years old")

Explanation:

• int() converts text input into a number so you can calculate or compare
