Interpretation of the game process
The computer randomly selects a word from a text, the string representation, and displays the length of the string. The user guesses one character by one character, and manually enters the guess result. There are a total of 6 guesses. After each guess, the computer informs the player that the player has been guessed. The guessing result and the remaining letter range that can be guessed have certain rules for the player's guessing process:
Cannot guess the characters that have already been guessed. Every time the guess is repeated, the computer will warn once, and there will be a total of 3 warning opportunities; characters other than uppercase and lowercase letters cannot be guessed, such as some special characters such as'#'. Every time you guess, you will be warned. The number of times is reduced by 1; when the number of warnings is gone, if the player continues to foul (repeated guessing, or guessing characters other than uppercase and lowercase letters), the number of guesses is reduced by 1; the letter guessed by the player is not in the target string secret_letters, if the guessed letter If it is a vowel, the number of guesses is reduced by 2 as a penalty. If it is a consonant, the number of guesses is reduced by 1. This guessing is too difficult for the player. Is it possible to implement an improved version of the game? Every time the player enters an asterisk * When the computer automatically outputs all words in the text that match the guessed result of the current player? This can greatly reduce the player's guessing range and reduce the difficulty of the game.
Modular programming ideas
How to realize this game? We must first implement some functions, these functions are as follows:
How the computer obtains the text How to randomly obtain the words from the text to determine whether the player guessed the characters correctly. Obtain the player’s guessed letters. Obtain the remaining guessable letters. The codes of the computer player interaction process are not given separately. The entire project is directly given below. The code

Note that the commented out part is to implement an improved version of the hangman game, a version with a computer prompt function. Whenever the user enters *, the computer outputs all the words in the text that match the current guessed result to narrow down the player Guess the range as a reminder. The game effect is as follows: If there is any problem with the project code, please feel free to point it out, thank you very much!
