建立：list = [5,7,9]
取值和改值：list[1] = list[1] * 5
列表尾插入：list.append(4)
去掉第0個值並返回第0個值的數值：list.pop(0)
去掉第0個值但不返回數值：del(list[0])
去掉具體某個值：list.remove(35)
函數function：
無參數：def function():
一個參數：def function(x):
2個參數：def function(y):
任意個參數：def add_function(*args):
函數range：
一個參數：range(n) 從第0位開始數n個位
兩個參數：range(m,n) 從第m位開始到第n-1位，遞增間隔為1
三個參數：range(m,n,i) 從第m位開始到第n-1位，遞增間隔為i
for item in list: 和 for i in range(len(list)): 等價
對list中的元素用separator作為間隔輸出： print separator.join(list)
如： list = ['a','b','c','d'] 一般的print list會輸出： ['a','b','c','d']。
而 print " ".join(list) 會輸出：a b c d(必須是雙的雙引號，單的雙引號不起作用)
接受鍵盤輸入：
guess_row = int(raw_input("Guess Row:"))
下面是一個自己寫的小程式：產生一個方陣和隨機的位置，叫玩家猜這個產生的位置是哪裡
複製代碼 代碼如下:
from random import randint
def creat_board(length):
board = []
for i in range(length):
board.append(['O'] * length)
return board
def print_board(x):
for row in x:
print " ".join(row)
def random_row(board):
return randint(0, len(board) - 1)
def random_col(board):
return randint(0,len(board[0]) - 1)
length = int(raw_input("Enter board's length you:"))
board = creat_board(length)
print_board(board)
turns = int(raw_input("Enter turns you want to play:"))
for turn in range(turns):
ship_row = random_row(board)
ship_col = random_col(board)
print "This is " + str(turn + 1) + "th time to guess:"
guess_row = int(raw_input("Enter the row you guess:"))
guess_col = int(raw_input("Enter the col you guess:"))
if guess_row == ship_row and guess_col == ship_col:
print "You win!"
break
else:
if (guess_row < 0 or guess_row > len(board) - 1) or (guess_col < 0 or guess_col > len(board) - 1):
print "Incorrect input!"
if turn == turns - 1:
print "Turns out!"
elif board[guess_row][guess_col] == 'X':
print "You have guessed it already!"
if turn == turns - 1:
print "Turns out!"
else:
print "You guess wrong!"
board[guess_row][guess_col] = 'X'
print_board(board)
if turn == turns - 1:
print "Turns out!"
曾經犯的錯誤：
1.建立board函數忘記返回一個board，所以它一直為空白，導致後面的操作都越界了；
2.產生隨機位置的時候，位置row和col的命名一直是跟產生的函數名一樣（random_row=random_row(board)），導致TypeError: 'int' object is not callable錯誤。
