Lesson 1: File Input and Output 📂

Learning Target: I can open, read, write, and append files in Python.

Opening and Reading Files

with open('example.txt', 'r') as file:
    content = file.read()
    print(content)

Writing to Files

with open('example.txt', 'w') as file:
    file.write('Hello, world!')

Appending to Files

with open('example.txt', 'a') as file:
    file.write('\nAppended text')

Your Turn!

Write a program that:

• Creates a new file and writes some text to it
• Reads the content of the file and prints it
• Appends additional text to the file

Lesson 2: Checking and Deleting Files 📂

Learning Target: I can check if a file exists and delete files in Python.

Checking if a File Exists

import os

if os.path.exists('example.txt'):
    print('File exists')
else:
    print('File does not exist')

Deleting Files

import os

if os.path.exists('example.txt'):
    os.remove('example.txt')
    print('File deleted')

Your Turn!

Write a program that:

• Checks if a file exists and prints a message
• Deletes the file if it exists

Lesson 3: Using the 'with' Statement 📂

Learning Target: I can use the 'with' statement for file operations in Python.

Using 'with' for File Handling

with open('example.txt', 'r') as file:
    content = file.read()
    print(content)

Your Turn!

Write a program that:

• Uses the 'with' statement to open and read a file
• Prints the content of the file

Lesson 4: Console Input and Output 🖥️

Learning Target: I can read input from the console and print formatted text in Python.

Reading Input from Console

name = input('Enter your name: ')
print('Hello, ' + name)

Printing Formatted Text

name = 'Alice'
age = 30
print('Name: {}, Age: {}'.format(name, age))
print(f'Name: {name}, Age: {age}')

Your Turn!

Write a program that:

• Asks the user for their name and age
• Prints a message with their name and age using formatted text

Lesson 5: Command-Line Arguments 🧾

Learning Target: I can use command-line arguments in Python.

Using Command-Line Arguments

import sys

if len(sys.argv) > 1:
    print('Arguments:', sys.argv[1:])
else:
    print('No arguments provided')

Your Turn!

Write a program that:

• Prints the command-line arguments provided to the script
