Study Notes
Program Design Fundamentals
- An algorithm is a set of well-defined instructions designed to solve a specific problem.
Programming Basics
- Programming is the process of giving a set of instructions to a computer so that it can execute specific tasks.
- A programming language is a formal system of notation used for writing computer programs.
- Python is a widely used general-purpose, high-level programming language.
Operators and Control Statements
- Operators are used to perform operations on variables and values.
- Conditional and control statements help programmers make decisions and execute/repeat different code blocks depending on whether a condition is met.
Pseudocode
- Pseudocode is a step-by-step description of an algorithm, written in simple English language text.
- Pseudocode is an intermediate state between an idea and its implementation in a high-level language.
- It helps programmers in planning the solution to the problem and readers in understanding the approach to the problem.
- Example: Write a pseudocode to find the sum of two numbers, which involves declaring variables, inputting values, and outputting the result.
Python Data Types
- A data type specifies the type of information that may be stored in a variable.
- Common data types in programming include:
- Integers (whole numbers)
- Characters (letters, numbers, spaces, symbols)
- Strings (sets of characters)
- Floats (decimal point numbers)
- Doubles (fractional numbers)
Sequential Structure
- Example: Write a Python program asking the user to enter their Name and Age, and calculate the year when the user will turn 90.
Conditional Structure
- Example: Write a Python program to check if a number is Even or Odd, based on the remainder of division by 2.
Control Structure
- Example: Write a Python program printing numbers from 1 to 10 using a for loop and the range function.
Review Questions
- Write a Python pseudocode and program for performing arithmetic operations on two numbers.
- Write a Python program to check if a number is Positive, Negative, or Zero.
- Write a Python program to display Even numbers between 10 and 30.
