python安装xlrd出现错误

一、安装xlrd出现错误

1.问题描述

在使用Python操作excel时,需要用到xlrd这个库,但是在安装xlrd时,会出现如下错误提示:

Command "python setup.py egg_info" failed with error code 1 in C:\Users\XXX\AppData\Local\Temp\pip-install-u1_sa0xl\xlrd\

2.问题分析

这个问题多半是由于网络原因引起的,因为大部分情况下,都是无法连接到pypi.org或者连接被中断导致的。也有很多人反映这是因为setuptools版本不太对引起的问题。

3.解决方法

方法一:升级setuptools版本

在terminal/command prompt里输入以下命令,然后重新安装xlrd:

pip install --upgrade setuptools

方法二:设置国内镜像

在terminal/command prompt里输入以下命令:

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple xlrd

二、Python简单小游戏代码大全

Python是一门高级语言,非常适合编写小游戏。以下是一些Python简单小游戏代码大全供参考:

1.猜数字游戏(Guess the Number)

思路:让玩家猜一个随机生成的数字。

Python代码:

import random

guessesTaken = 0

print('Hello! What is your name?')

myName = input()

number = random.randint(1, 20)

print('Well, ' + myName + ', I am thinking of a number between 1 and 20.')

while guessesTaken < 6:

print('Take a guess.')

guess = input()

guess = int(guess)

guessesTaken = guessesTaken + 1

if guess < number:

print('Your guess is too low.')

if guess > number:

print('Your guess is too high.')

if guess == number:

break

if guess == number:

guessesTaken = str(guessesTaken)

print('Good job, ' + myName + '! You guessed my number in ' + guessesTaken + ' guesses!')

if guess != number:

number = str(number)

print('Nope. The number I was thinking of was ' + number)

2.猜单词游戏(Guess the Word)

思路:从一个列表中随机选择一个单词,让玩家猜这个单词是什么。

Python代码:

import random

WORDS = ['python', 'java', 'ruby', 'csharp', 'php']

word = random.choice(WORDS)

correct = word

jumble = ''

while word:

position = random.randrange(len(word))

jumble += word[position]

word = word[:position] + word[(position + 1):]

print('The jumble is:', jumble)

guess = input('Your guess: ')

while guess != correct and guess != '':

print('Sorry, that is not it.')

guess = input('Your guess: ')

if guess == correct:

print('You guessed it! Congratualations!')

3.贪吃蛇游戏(Snake Game)

思路:编写一个小程序,模拟贪吃蛇的游戏过程。

Python代码:

import turtle

import time

import random

delay = 0.1

#Score

score = 0

high_score = 0

wn = turtle.Screen()

wn.title("Snake Game by @Anson")

wn.bgcolor("green")

wn.setup(width=600, height=600)

#Snake head

head = turtle.Turtle()

head.speed(0)

head.shape("square")

head.color("black")

head.penup()

head.goto(0,0)

head.direction = "stop"

#Snake food

food = turtle.Turtle()

food.speed(0)

food.shape("circle")

food.color("red")

food.penup()

food.goto(0,100)

segments = []

#Scoreboard

pen = turtle.Turtle()

pen.speed(10)

pen.shape("square")

pen.color("white")

pen.penup()

pen.hideturtle()

pen.goto(0, 250)

pen.write("Score: {} High Score: {}".format(score, high_score), align="center", font=("Courier", 24, "normal"))

#Functions

def go_up():

if head.direction != "down":

head.direction = "up"

def go_down():

if head.direction != "up":

head.direction = "down"

def go_left():

if head.direction != "right":

head.direction = "left"

def go_right():

if head.direction != "left":

head.direction = "right"

def move():

if head.direction == "up":

y = head.ycor()

head.sety(y + 20)

if head.direction == "down":

y = head.ycor()

head.sety(y - 20)

if head.direction == "left":

x = head.xcor()

head.setx(x - 20)

if head.direction == "right":

x = head.xcor()

head.setx(x + 20)

#Keyboard bindings

wn.listen()

wn.onkeypress(go_up, "Up")

wn.onkeypress(go_down, "Down")

wn.onkeypress(go_left, "Left")

wn.onkeypress(go_right, "Right")

#Main game loop

while True:

wn.update()

#Check for collision with border

if head.xcor()>290 or head.xcor()<-290 or head.ycor()>290 or head.ycor()<-290:

time.sleep(1)

head.goto(0,0)

head.direction = "stop"

#Hide the segments

for segment in segments:

segment.goto(1000, 1000)

#Clear the segments list

segments.clear()

#Reset the score

score = 0

#Reset the delay

delay = 0.1

pen.clear()

pen.write("Score: {} High Score: {}".format(score, high_score), align="center", font=("Courier", 24, "normal"))

#Check for collision with food

if head.distance(food) < 20:

#Move the food to a random spot

x = random.randint(-290, 290)

y = random.randint(-290, 290)

food.goto(x,y)

#Add a segment

new_segment = turtle.Turtle()

new_segment.speed(0)

new_segment.shape("square")

new_segment.color("grey")

new_segment.penup()

segments.append(new_segment)

#Shorten the delay

delay -= 0.001

#Increase the score

score += 10

if score > high_score:

high_score = score

pen.clear()

pen.write("Score: {} High Score: {}".format(score, high_score), align="center", font=("Courier", 24, "normal"))

#Move the end segments first in reverse order

for index in range(len(segments)-1, 0, -1):

x = segments[index-1].xcor()

y = segments[index-1].ycor()

segments[index].goto(x, y)

#Move segment 0 to where the head is

if len(segments) > 0:

x = head.xcor()

y = head.ycor()

segments[0].goto(x,y)

move()

#Check for head collision with the body

for segment in segments:

if segment.distance(head) < 20:

time.sleep(1)

head.goto(0,0)

head.direction = "stop"

for segment in segments:

segment.goto(1000, 1000)

segments.clear()

score = 0

delay = 0.1

pen.clear()

pen.write("Score: {} High Score: {}".format(score, high_score), align="center", font=("Courier", 24, "normal"))

time.sleep(delay)

wn.mainloop()
