Study Notes
Iterating over a List
- Method 1: Using for loop to iterate over a list, example:
for item in list: print('college ', i, ' is ', item) - Method 2: Using for loop and range() function to iterate over a list, example:
for i in range(length): print(list[i]) - Method 3: Using while loop to iterate over a list, example:
while i < length: print(list[i])
Mutability and List Operations
- Mutable objects can be changed after creation, immutable objects cannot
- Append: adds an item to a list, example:
x.append(10) - Extend: appends a sequence to a list
Operator Precedence
- Multiplication gets evaluated before addition
- Parentheses () can override the precedence of arithmetic operators
- Examples of operator precedence with different expressions
Comments in Python
- Single-line comments start with
#symbol - Multi-line comments use triple double quotes
""" """or single quotes `''' ''' - Example of single-line and multi-line comments
Modules in Python
- A Python module is a file containing Python code, including functions, classes, and variables
- Modules can be used to break down large programs into smaller, manageable files
- Example of creating and using a module
Exception Handling
- Example of try-except-finally block to handle ZeroDivisionError
- Example of try-except block to handle ValueError and generic Exception
- Importance of exception handling in Python
