Sak*_*han 5 python user-input menu getchar python-3.x
首先,我对Python完全陌生,刚刚开始学习它。我知道很多关于 C++ 的东西,但我只是尝试用 Python 实现其中一些。
我已经对其进行了大量搜索,但找不到任何符合我要求的解决方案。请看下面的代码,
import os
class _Getch:
"""Gets a single character from standard input. Does not echo to the
screen."""
def __init__(self):
try:
self.impl = _GetchWindows()
except:
print("Error!")
def __call__(self): return self.impl()
class _GetchWindows:
def __init__(self):
import msvcrt
def __call__(self):
import msvcrt
return msvcrt.getch()
def mainfun():
check = fh = True
while check:
fh = True
arr = [[0, 0, 0], [0, 0, 0], [0, 0, 0]]
print ("Welcome to Tic Tac Toe Game!!!\n\n")
print("Enter 1 to Start Game")
print("Enter 2 to Exit Game")
a = _Getch()
if a == "1":
while fh:
os.system("cls")
drawboard()
playermove()
fh = checkresult()
elif a == "2":
break

正如您所看到的,我在这里尝试做的是要求用户按 1 和 2 中的一个数字,然后将该数字存储在“a”中,然后将其用于我的要求。
现在,我第一次尝试使用这个,
input('').split(" ")[0]

但这没有用。它要求我在输入 1 或 2 后始终按 Enter 键。所以,这不起作用。
然后我找到了Getch这个类并实现了它。长话短说,它让我陷入了一个永无休止的循环,我的结果现在是这样的,
Welcome to Tic Tac Toe Game!!!
Enter 1 to Start Game
Enter 2 to Exit Game
Press Enter to Continue....
Welcome to Tic Tac Toe Game!!!
Enter 1 to Start Game
Enter 2 to Exit Game
Press Enter to Continue....
Welcome to Tic Tac Toe Game!!!
Enter 1 to Start Game
Enter 2 to Exit Game
Press Enter to Continue....

这是一个永无休止的循环......即使我按“1”或“2”等任何键,它仍然不会停止并继续执行此操作并且不输入任何功能。
我想要的是类似这样的功能,
换句话说,我只想在Python中替代C++的getch()命令。我已经尝试了很多方法来找到它,但我找不到。请向我提出一个问题,该问题提供了该确切问题的解决方案或在此处提供解决方案。谢谢。
编辑:请注意这不是完整的代码。我只提供了相关的代码。如果有人需要查看整个代码,我也很乐意分享。
完整代码如下,
import os
import keyboard
def getch():
alphabet = list(map(chr, range(97, 123)))
while True:
for letter in alphabet: # detect when a letter is pressed
if keyboard.is_pressed(letter):
return letter
for num in range(10): # detect numbers 0-9
if keyboard.is_pressed(str(num)):
return str(num)
arr = [[0, 0, 0], [0, 0, 0], [0, 0, 0]]
playerturn = 1
def drawboard():
global playerturn
print("Player 1 (X) - Player 2 (O)\n")
print("Turn: Player " + str(playerturn))
print("\n")
for i in range(3):
print (" ", end='')
for j in range(3):
print(arr[i][j], end='')
if j == 2:
continue
print(" | ", end='')
if i == 2:
continue
print("")
print("____|____|____")
print(" | | ")
def playermove():
global playerturn
row = col = 0
correctmove = False
print("\n\nMake your Move!\n")
while not correctmove:
row = int(input("Enter Row: "))
col = int(input("Enter Col: "))
if (3 > row > -1) and (-1 < col < 3):
for i in range(3):
for j in range(3):
if arr[row][col] == 0:
correctmove = True
if playerturn == 1:
arr[row][col] = 1
else:
arr[row][col] = 2
playerturn += 1
if playerturn > 2:
playerturn = 1
if not correctmove:
print ("Wrong Inputs, please enter again, ")
def checkwin():
for player in range(1, 3):
for i in range(3):
if arr[i][0] == player and arr[i][1] == player and arr[i][2] == player: return player
if arr[0][i] == player and arr[1][i] == player and arr[2][i] == player: return player
if arr[0][0] == player and arr[1][1] == player and arr[2][2] == player: return player
if arr[0][2] == player and arr[1][1] == player and arr[2][0] == player: return player
return -1
def checkdraw():
for i in range(3):
for j in range(3):
if arr[i][j] == 0:
return False
return True
def checkresult():
check = checkwin()
if check == 1:
os.system('cls')
drawboard()
print("\n\nPlayer 1 has won the game!!\n")
elif check == 2:
os.system('cls')
drawboard()
print("\n\nPlayer 2 has won the game!!\n")
elif check == 3:
os.system('cls')
drawboard()
print("\n\nThe game has been drawn!!\n")
else:
return True
return False
def mainfun():
check = fh = True
while check:
os.system("cls")
fh = True
arr = [[0, 0, 0], [0, 0, 0], [0, 0, 0]]
print ("Welcome to Tic Tac Toe Game!!!\n\n")
print("Enter 1 to Start Game")
print("Enter 2 to Exit Game")
a = getch()
if a == "1":
while fh:
os.system("cls")
drawboard()
playermove()
fh = checkresult()
elif a == "2":
break
print ("Press any key to continue...")
getch()
mainfun()

EDIT2:通过使用键盘模块解决了问题...这里的下一个问题是如何在调用 getch() 函数后删除存储在输入缓冲区中的数据?因为缓冲区中的数据将显示在下一个输入上(当我接收行和列时),而我不希望发生这种情况。我找到了适用于 Linux 的解决方案,但不适用于 Windows(或 Pycharm)
看起来这个功能并不在标准 python 库中,但你可以重新创建它。
首先,安装模块“键盘”
$ pip3 install keyboard

然后你可以使用keyboard.is_pressed()来查看是否有任何一个字符被按下。

编辑:对于 unix,您需要使用 sudo 运行脚本。这段代码在 Windows 上应该可以正常工作。
