Note

• Code snippet to raise error if input is invalid
• Another article for asking user to enter the correct value

Coin Flip and Dice Game:

• Welcome User
• Ask user to choose the game
• Validate user's choice if they entered 1 or 2

Coin Flip:

• Ask user to predict heads or tails
• Check if the entry is valid, ask again if entry is invalid
• If valid:
  • Generate random number from 1 to 2
  • compare user's entry if it matches the random number
    • if yes:
      • Let user know they got it right
      • add a score +1
      • Ask if they want to play again
        • if no end the game
        • if yes go back to game choices
    • if no:
      • let user know that they got it wrong
      • ask to play again
        • if no end the game
        • if yes go back to game choices

Dice Game:

• Ask user to predict dice number

• Check if entry is from range 1 to 6 only, if invalid ask again.

• If valid do this:

  • Generate a number from 1 to 6
  • Compare user entry from the generated number
    • if yes:
      • Let user know they got it right
      • add a score +1
      • Ask if they want to play again
        • they can play again
        • choose another game
        • end the program
    • if no:
      • let user know that they got it wrong
      • ask to play again
        • they can play again
        • choose another game
        • end the program

  Edits:

  • addressed the input case-sensitivity based on a feedback received via Discord

  # From
  if ans == "y":
  # To
  if ans.lower() == "y":
  

  • move the .lower at the end of input() feedback via Discord
