python爬虫小白入门笔记，python五子棋游戏代码大全

一、Python爬虫小白入门笔记

Python是现在非常流行的编程语言之一，而Python爬虫更是其独特的应用之一。Python爬虫可以用于爬取各种网站的信息和数据，实现数据分析和业务应用，尤其是对于数据分析和数据挖掘的人员，学会Python爬虫是非常有帮助的。

以下是Python爬虫小白入门笔记，希望对初学者有所帮助：

1. Python基础语法学习

在学习Python爬虫之前，首先需要学习Python基础语法。Python语言可以比较快速地学习，但是基础语法的掌握是非常重要的。

2. 爬虫相关知识学习

爬虫涉及到的知识比较多，包括HTTP协议、HTML、CSS、JavaScript等技术，需要花费一定的时间学习。

3. 爬虫工具学习

爬虫工具的选择也非常重要，常用的爬虫工具有BeautifulSoup、Scrapy等，在学习Python爬虫时需要尝试选择合适的工具。

4. 实战演练

在学习过程中需要多进行一些实战演练，尝试从网站上爬取数据，进行数据分析和业务应用。

二、Python五子棋游戏代码大全

五子棋游戏是一款经典的益智游戏，在Python中也有很多五子棋游戏的相关代码。以下是Python五子棋游戏代码大全：

1. 传统五子棋

```

import numpy as np

class Board:

def __init__(self, n):

self.n = n

self.board = np.zeros((n, n))

self.winner = None

def place(self, row, col, player):

assert self.board[row, col] == 0, "Board position not empty!"

self.board[row, col] = player

self.check_winner(row, col)

def as_string(self):

rows = []

for row in self.board:

row_str = " ".join([str(int(x)) for x in row])

row_str = row_str.replace("0", ".")

rows.append(row_str)

return "\n".join(rows)

def check_winner(self, row, col):

directions = [(0,1),(1,0),(1,1),(1,-1)]

for dr, dc in directions:

r, c = row, col

count = 0

while (0 <= r < self.n and 0 <= c < self.n

and self.board[r, c] == self.board[row, col]):

count += 1

r, c = r + dr, c + dc

r, c = row - dr, col - dc

while (0 <= r < self.n and 0 <= c < self.n

and self.board[r, c] == self.board[row, col]):

count += 1

r, c = r - dr, c - dc

count -= 1

if count >= 5:

self.winner = self.board[row, col]

class Game:

def __init__(self, n):

self.n = n

self.players = [1, 2]

self.board = Board(n)

self.current_player = self.players[0]

def next_player(self):

if self.current_player == self.players[0]:

self.current_player = self.players[1]

else:

self.current_player = self.players[0]

def play(self):

while not self.board.winner:

print("Current board:\n", self.board.as_string())

print("Current player:", self.current_player)

x, y = input("Enter row and col separated by a space: ").split()

x, y = int(x), int(y)

self.board.place(x, y, self.current_player)

self.next_player()

print("Winner is player", self.board.winner)

game = Game(15)

game.play()

```
