Level 5: In Python, you can use the `print()` function to display text or other information on the screen. To print a string, enclose it in quotation marks. For example: ```python print("Hello, world!") ``` This will output: ``` Hello, world! ``` ### Using Variables You can also use variables to store text or numbers and then print them. For instance: ```python message = "Welcome to the course!" print(message) ``` ### Printing Multiple Items You can print multiple items by separating them with commas. Each item will be separated by a space in the output: ```python first_name = "Jane" last_name = "Doe" print("Hello,", first_name, last_name) ``` This will output: ``` Hello, Jane Doe ``` ### Print Function with Formatting The `print()` function can be used with f-strings for formatting, which allow you to embed expressions inside string literals, using curly braces. Here's an example: ```python name = "Alice" age = 30 print(f"My name is {name} and I am {age} years old.") ``` This will output: ``` My name is Alice and I am 30 years old. ``` ### Special Characters You can include special characters in strings, like newlines (`\n`) or tabs (`\t`). Here's an example with a newline: ```python print("Hello, world!\nHow are you?") ``` The output will be: ``` Hello, world! How are you? ``` This is a basic introduction to printing in Python. As you continue learning, you'll encounter more ways to control and format your printed output.
