| | | elif x == 0: | |
| | | print(“Zero”) | |
| | | else: | |
| | | print(“Negative”) | |
| **For Loop Block** | A block of code that iterates over a sequence. | for i in range(5): | The for statement is followed by an indented block. |
| | | print(i) | |
| **While Loop Block** | A block of code that repeats as long as a condition is true. | while x > 0: | The while statement is followed by an indented block. |
| | | x -= 1 | |
| **Try-Except Block** | A block of code that handles exceptions (runtime errors). | try: | Begins with try, followed by one or more except blocks. |
| | | result = 1 / x | |
| | | except ZeroDivisionError: | |
| | | print(“Cannot divide by zero”) | |
| **With Block** | A block of code that simplifies resource management (e.g., opening files). | with open(“file.txt”) as f: | The with statement is followed by an indented block. |
| | | content = f.read() | |
| **List Comprehension** | A concise block for creating lists in a single line. | squares = [x2 for x in range(10) if x % 2 == 0] | List comprehensions are single-line blocks enclosed in brackets. |
| **Dictionary Comprehension** | A concise block for creating dictionaries in a single line. | squares_dict = {x: x2 for x in range(5)} | Dictionary comprehensions are single-line blocks enclosed in braces {}. |
| **Docstring Block** | A block of code that provides documentation for a module, class, or function. | def greet(): | Docstrings are enclosed in triple quotes ”””. |
