Question

次のPythonコードが動作しようとしています。私がしようとしているのは、入力された文字の代わりにパスワードの入力ボックスのために、アスタリスクを表示することです。

他の変数を使用して表示しようとしましたが、機能しませんでした。私は変数に格納されている正しいアスタリスク数を得ることができましたが、アスタリスクでパスワードボックスにテキストを上書きするのに助けが必要です。

コードは次のとおりです。

import pygame, pygame.font, pygame.event, pygame.draw, string 
from pygame.locals import * 
import hashlib, uuid 

string='' 
hashed_password='' 
current_string_p=[] 
display_p=[] 
symbol='*' 

def get_key(): 
    while 1: 
    event = pygame.event.poll() 
    if event.type == KEYDOWN: 
     return event.key 
    else: 
     pass 

def display_box(screen, message): 
    "Print a message in a box in the middle of the screen" 
    fontobject = pygame.font.Font(None,18) 
    pygame.draw.rect(screen, (0,0,0), 
        ((screen.get_width()/2) - 100, 
        (screen.get_height()/2) - 10, 
        200,20), 0) 
    pygame.draw.rect(screen, (255,255,255), 
        ((screen.get_width()/2) - 102, 
        (screen.get_height()/2) - 12, 
        204,24), 1) 

    if len(message) != 0: 
    screen.blit(fontobject.render(message, 1, (255,255,255)), 
       ((screen.get_width()/2) - 100, (screen.get_height()/2) - 10)) 
    pygame.display.flip() 

def ask(screen, question): 
    "ask(screen, question) -> answer" 
    pygame.font.init() 
    current_string_un = [] 
    display_box(screen, question + ": " + string.join(current_string_un)) 
    while 1: 
    inkey = get_key() 
    if inkey == K_BACKSPACE: 
     current_string_un = current_string_un[0:-1] 
    elif inkey == K_RETURN: 
     break 
    elif inkey == K_LSHIFT or inkey == K_RSHIFT: 
     inkey=get_key() 
     if inkey <= 127: 
     upper_case=inkey-32 
     current_string_un.append(chr(upper_case)) 
    elif inkey <= 127: 
     current_string_un.append(chr(inkey)) 
    display_box(screen, question + ": " + string.join(current_string_un)) 
    return string.join(current_string_un) 
#password

    global current_string_p 
    current_string_p = [] 
    display_p=[] 
    pro=''.join(display_p) 
    display_box(screen, question + ": " + pro) 
    while 1: 
    inkey = get_key() 
    if inkey == K_BACKSPACE: 
     current_string_p = current_string_p[0:-1] 
     display_p = display_p[0:-1] 
    elif inkey == K_RETURN:

     break

     for character in current_string_p: 
      display_p.append(symbol) 
     pro=''.join(display_p) 
     display_box.blit(screen, question + ": " + pro) 
     current_string_p.append(chr(upper_case)) 
    elif inkey <= 127: 
     for character in current_string_p: 
     display_p.append(symbol) 
     pro=''.join(display_p) 
     display_box.blit(screen, question + ": " + pro) 
     current_string_p.append(chr(inkey)) 


## return string.join(display_p) 
    return display_p 
## return string.join(current_string_p) 

def strong_password(password): 
    #a strong password will have a capital letter, a lowercase letter and a number 
    passloop = 1 
    hasdigit = 0 
    uppercase = 0 
    #checks each character to check password meets requirements 
    for character in password: 
     if character.isdigit(): 
      hasdigit += 1 
     else: 
      pass 
     if character == character.upper(): 
      if character.isdigit(): 
       pass 
      else: 
       uppercase += 1 
     else: 
      pass 
    if hasdigit > 0 and uppercase > 0: 
     passloop = 2 
     print('strong password') 
    else: 
     passloop = 1 
     print('weak password') 

def main(): 
    global display_p 
    display_p=[] 
    screen = pygame.display.set_mode((320,240)) 
    print (ask(screen, "Username") + " was entered") 
    x = ask(screen, "Password") 
    for character in x: 
    display_p.append(symbol) 
    pro=''.join(display_p) 
    print (x + " was entered") 
    print(pro) 
    #check password security 
    strong_password(x) 
    #hash password 
    salt = "5gz" 
    hashing_password = x+salt 
    h = hashlib.md5(hashing_password.encode()) 
    print(h.hexdigest()) 

if __name__ == '__main__': 
     main() 

私は、問題は、このセクションにあると思う：

#password 
    global display_p 
    global current_string_p 
    current_string_p = [] 
    display_p=[] 
    pro=''.join(display_p) 
    display_box(screen, question + ": " + pro) 
    while 1: 
    inkey = get_key() 
    if inkey == K_BACKSPACE: 
     current_string_p = current_string_p[0:-1] 
     display_p = display_p[0:-1] 
    elif inkey == K_RETURN: 
##  print(display_p)) 
     break 
    elif inkey == K_LSHIFT or inkey == K_RSHIFT: 
     inkey=get_key() 
     if inkey <= 127: 
     upper_case=inkey-32 
     for character in current_string_p: 
      display_p.append(symbol) 
     pro=''.join(display_p) 
     display_box.blit(screen, question + ": " + pro) 
     current_string_p.append(chr(upper_case)) 
    elif inkey <= 127: 
     for character in current_string_p: 
     display_p.append(symbol) 
     pro=''.join(display_p) 
     display_box.blit(screen, question + ": " + pro) 
     current_string_p.append(chr(inkey)) 


## return string.join(display_p) 
    return display_p 
## return string.join(current_string_p)

あなたは自分のパスワードの'*'倍の長さをレンダリングすることができます。

import pygame as pg 


pg.init() 
FONT = pg.font.Font(None, 42) 


def main(): 
    screen = pg.display.set_mode((640, 480)) 
    clock = pg.time.Clock() 
    password = '' 

    done = False 

    while not done: 
     for event in pg.event.get(): 
      if event.type == pg.QUIT: 
       done = True 
      elif event.type == pg.KEYDOWN: 
       if event.key == pg.K_RETURN: 
        # Do something with the password and reset it. 
        print(password) # I just print it to see if it works. 
        password = '' 
       else: # Add the character to the password string. 
        password += event.unicode 

     screen.fill((30, 30, 30)) 
     # Render the asterisks and blit them. 
     password_surface = FONT.render('*'*len(password), True, (70, 200, 150)) 
     screen.blit(password_surface, (30, 30)) 

     pg.display.flip() 
     clock.tick(30) 


if __name__ == '__main__': 
    main() 
    pg.quit()
