Study Notes
Python Code Basics
- Concatenation with
printin Python can include converting data types usingint()orstr(). - Common data type conversions:
int()converts values to integers.str()converts values to strings.
Commenting Code
- Use
#for inline comments in Python to provide explanations which help collaborators understand your code.
Importing Functions
- To import the
sqrtfunction and alias it assquareRoot, use:from math import sqrt as squareRoot.
Error Handling in File Operations
- Use
tryandexceptfor managing file operation errors. - If accessing a non-existent file, it can lead to a runtime error if not properly handled.
Reading Files and Handling Blank Lines
- To read lines from a file and ignore blank lines, implement checks such as
if line != '\n':.
Debugging Infinite Loops
- Review conditional statements and calculations to prevent infinite loops, such as avoiding division by zero.
Code Documentation
- Use clear syntax before function definitions to explain what the function does, like using
#for comments.
Code Completion for Patterns
- When writing conditional statements, ensure they correctly reflect the logic necessary for the function.
Employee Number Validation
- Validate employee numbers with specific string formats using
splitandisdigit()to ensure proper structure.
Function for Root Calculation
- Structure logic to handle negative and positive numbers in root calculations appropriately.
Age-Based Rating System
- Implement if-elif-else statements based on age criteria for assigning ratings correctly.
Iterating Over Product Lists
- Use loops effectively to iterate through lists and include
breakstatements to exit upon finding target conditions.
Counting Characters in Text
- To count specific letters in text, iterate through word lists and increment counts based on character matches.
Calculating Average Velocity
- When calculating velocity, ensure type conversion for distance and time to maintain precision in calculations.
DVD Rental Cost Determination
- Factor in different rates based on rental duration and return conditions, including additional charges for late returns.
