這個(gè)教程，我們將展示如何用python創(chuàng)建一個(gè)井字游戲。 其中我們將使用函數(shù)、數(shù)組、if條件語句、while循環(huán)語句和錯(cuò)誤捕獲等。
首先我們需要?jiǎng)?chuàng)建兩個(gè)函數(shù)，第一個(gè)函數(shù)用來顯示游戲板:
def print_board(): for i in range(0,3): for j in range(0,3): print map[2-i][j], if j != 2: print "|", print ""
這我們使用兩個(gè)for循環(huán)來遍歷map，該map是一個(gè)包含了位置信息的二維數(shù)組。
游戲板看起來是這樣的:
| | | | | | X | X | O | X | O | O | X X | X | XX | X | XX | X | X
下面我們需要一個(gè)函數(shù)check_done()來檢查游戲是否結(jié)束。如果結(jié)束，則返回True并打印消息。
def check_done(): for i in range(0,3): if map[i][0] == map[i][1] == map[i][2] != " " / or map[0][i] == map[1][i] == map[2][i] != " ": print turn, "won!!!" return True if map[0][0] == map[1][1] == map[2][2] != " " / or map[0][2] == map[1][1] == map[2][0] != " ": print turn, "won!!!" return True if " " not in map[0] and " " not in map[1] and " " not in map[2]: print "Draw" return True return False
有幾個(gè)地方需要檢查，首先檢查水平和垂直方向，是否有一行或一列不為空且包含有三個(gè)相同的符號(hào)，然后我們?cè)贆z查斜方向。如果上面有一個(gè)方向滿足，游戲結(jié)束并打印“Won!!!”。請(qǐng)注意檢查變量改變，它用來標(biāo)記當(dāng)前是哪一位玩家。
同時(shí)我們需要檢查當(dāng)前游戲板是否被填滿且沒有人獲勝，游戲平局。
有了上面的兩個(gè)函數(shù)，下面我們創(chuàng)建3個(gè)變量:
turn = "X"map = [[" "," "," "], [" "," "," "], [" "," "," "]]done = False
turn : 輪到誰
map : 游戲板
done : 游戲是否結(jié)束
現(xiàn)在啟動(dòng)游戲:
while done != True: print_board() print turn, "'s turn" print moved = False while moved != True:
這里使用了while循環(huán)直到游戲結(jié)束并返回true.在這個(gè)循環(huán)里面，使用了另外一個(gè)while循環(huán)來檢查玩家是否移動(dòng)，如果玩家沒有移動(dòng)，則程序會(huì)跳到下一次循環(huán)。
下一步告訴玩家怎么玩:
print "Please select position by typing in a number between 1 and 9, see below for which number that is which position..." print "7|8|9" print "4|5|6" print "1|2|3" print try: pos = input("Select: ") if pos <=9 and pos >=1:我們期望玩家輸入一個(gè)數(shù)字，檢查該數(shù)字是否是在1到9之間。另外，我們這里需要一段錯(cuò)誤處理邏輯，我們還需要需要檢查玩家是否能移動(dòng)到一個(gè)位置:
Y = pos/3 X = pos%3 if X != 0: X -=1 else: X = 2 Y -=1
以下是全部的代碼:
def print_board(): for i in range(0,3): for j in range(0,3): print map[2-i][j], if j != 2: print "|", print "" def check_done(): for i in range(0,3): if map[i][0] == map[i][1] == map[i][2] != " " / or map[0][i] == map[1][i] == map[2][i] != " ": print turn, "won!!!" return True if map[0][0] == map[1][1] == map[2][2] != " " / or map[0][2] == map[1][1] == map[2][0] != " ": print turn, "won!!!" return True if " " not in map[0] and " " not in map[1] and " " not in map[2]: print "Draw" return True return False turn = "X"map = [[" "," "," "], [" "," "," "], [" "," "," "]]done = False while done != True: print_board() print turn, "'s turn" print moved = False while moved != True: print "Please select position by typing in a number between 1 and 9,/ see below for which number that is which position..." print "7|8|9" print "4|5|6" print "1|2|3" print try: pos = input("Select: ") if pos <=9 and pos >=1: Y = pos/3 X = pos%3 if X != 0: X -=1 else: X = 2 Y -=1 if map[Y][X] == " ": map[Y][X] = turn moved = True done = check_done() if done == False: if turn == "X": turn = "O" else: turn = "X" except: print "You need to add a numeric value"新聞熱點(diǎn)
