Pseudocode is an informal high-level description of the operating principle of a computer program or other algorithm. It uses the structural conventions of a normal programming language, but is intended for human reading rather than machine reading.
Pseudocode is a simple way of writing programming code in English. Pseudocode is not actual programming language. It uses short phrases to write code for programs before you actually create it in a specific language. Once you know what the program is about and how it will function, then you can use pseudocode to create statements to achieve the required results for your program.
Common psuedocode verbs
Common Action Keywords
Several keywords are often used to indicate common input, output, and processing operations.
- Input: READ, OBTAIN, GET
- Output: PRINT, DISPLAY, SHOW
- Compute: COMPUTE, CALCULATE, DETERMINE
- Initialize: SET, INIT
- Add one: INCREMENT, BUMP
Examples of pseudocode
 Example 1:
If student's grade is greater than or equal to 60 Print "passed" else Print "failed"
Question for you to think about:
 Example 2:
Set total to zero Set grade counter to one While grade counter is less than or equal to ten Input the next grade Add the grade into the total Set the class average to the total divided by ten Print the class average.
Do you understand this?
Please paste this code into your Python IDE :
import random secret_number = random.randint(0,100) guess = 0 game = 1 while True: print("This is guess: " + str(guess)) print("This is game: " + str(game)) players_guess = input("I'm thinking of a number between 1 and 100. What is your guess: ") if players_guess == secret_number: print("You won!") play_again = raw_input("Do you want to play again (Y or N)? ") if play_again == "Y" or play_again == "y" or play_again == "yes": guess == 0 game = game + 1 secret_number = random.randint(0,100) else: break elif players_guess < secret_number: print("This guess is to low.") guess = guess + 1 elif players_guess > secret_number: print("This guess is to high") guess = guess + 1

Pick a random number. Set the secret number to a number that is between 0 and 100. Set the number of guesses to start with. Set the number of games to 1. While true, print ("This is guess: " +(number of guesses) and print ("This is game: + (number of games). Obtain the player's guess by asking for an input of their guess. If the player guessed the secret number, print ("You won!") and ask "do you want to play again?" If play again is "y", set guess back to zero and add one to the number of games played. Also, choose another different random secret number between 0 and 100. Else, if play again is no, end or break the code. If the player's guess is is lower than the secret number, print ("The guess is too low.") and add one to the number of guesses. Else, if the number is higher than the secret number, print ("This guess is too high.") and add one to the number of guesses.
Why is this so important?
When you are first building a program, we don't really care about the actual LANGUAGE or SYNTAX you will use. Rather, we care about your logic. Pseudocode helps you by forcing you to think logically rather than about syntax.
