Displaying Outputs
Master output methods: printing multiple items with commas, string concatenation (+), default spaces, and basic escape codes.
1. The print() Function
We use the built-in print() function to send text messages and outputs to the screen.
2. Commas vs. Plus (+) in print()
- Comma separation (
,): Combines multiple items of any type, automatically adding a space between them. E.g.,print("Age:", 22)works perfectly! - Concatenation (
+): Joins strings together directly. It does NOT add spaces automatically and will raise aTypeErrorif you try to join a string and a number.
3. Escape Sequences
Escape characters let you format the output layout inside a string. They begin with a backslash \:
\n: Moves the text following it onto a new line.\t: Inserts a horizontal tab space (equal to 4 spaces) for alignment.
💻 Python Code Examples
Example 1: Printing Text Strings
print("Hello, Python Course!")Description: Outputs a standard text string to the terminal console.
Example 2: Comma Separated Outputs
print("Python", "is", "fun")Description: Uses commas to print multiple strings, automatically inserting spaces.
Example 3: Concatenating Text with +
print("Python" + "is" + "fun") # Output: PythonisfunDescription: Joins text strings together directly with no spaces added.
Example 4: Mixing Types with Commas
print("Score:", 100)Description: Safely combines text and a number using a comma without throwing errors.
Example 5: Formatting with Newlines (\n)
print("Line 1\nLine 2")Description: Uses \n to break the output string into two lines.
Example 6: Formatting with Tabs (\t)
print("Item:\tBook\nPrice:\t$15")Description: Uses \t to insert tabs and align text attributes.
