实例1、创建并打开记录蚂蚁庄园动态的文件
print("\n","="*10,"蚂蚁庄园动态","="*10)
file=open('message.txt','w')
print("\n即将显示……\n")
实例2、向蚂蚁庄园的动态文件写入一条信息
print("\n","="*10,"蚂蚁庄园动态","="*10)
file=open('message.txt','w')
file.write("你使用了1张加速卡，小鸡撸起袖子开始双手吃饲料，进食速度大大加快。\n")
print("\n写入了一条动态……\n")
file.close()
print("\n","="*10,"蚂蚁庄园动态","="*10)
file=open('message.txt','a')
file.write("mingri的小鸡在你的庄园待了22分钟，吃了6g饲料之后，被你赶走了。\n")
print("\n追加了一条动态……\n")
file.close()
实例3、显示蚂蚁庄园的动态
print("\n","="*25,"蚂蚁庄园动态","="*25,"\n")
with open('message.txt','r') as file:
message=file.read()
print(message)
print("\n","="*29,"over","="*29,"\n")
实例4、逐行显示蚂蚁庄园的动态
print("\n","="*35,"蚂蚁庄园动态","="*35,"\n")
with open('message.txt','r') as file:
number=0
while True:
number+=1
line=file.readline()
if line=='':
break
print(number,line,end="\n")
print("\n","="*39,"over","="*39,"\n")
实例5、遍历指定目录
import os
path="C:\\demo"
print("【",path,"】目录下包括的文件和目录:")
for root,dirs,files in os.walk(path,topdown=True):
for name in dirs:
print("●",os.path.join(root,name))
for name in files:
print("◎",os.path.join(root,name))
实例6、获取文件基本信息
import os
fileinfo =os.stat("message.txt")
print("文件完整路径:",os.path.abspath("message.txt"))
print("索引号:",fileinfo.st_ino)
print("设备名:",fileinfo.st_dev)
print("文件大小:",fileinfo.st_size,"字节")
print("最后一次访问时间:",fileinfo.st_atime)
print("最后一次修改时间:",fileinfo.st_mtime)
print("最后一次状态变化时间:",fileinfo.st_ctime)
import os
def formatTime(longtime):
'''格式化日期时间的函数
longtime:要格式化的时间
'''
import time
return time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(longtime))
def formatByte(number):
'''格式化文件大小的函数
number:要格式化的字节数
'''
for (scale,label) in[(1024*1024*1024,"GB"),(1024*1024,"MB"),(1024,"KB")]:
if number>=scale:
return "%.2f%s"%(number*1.0/scale,label)
elif number==1:
return "1字节"
else:
byte="%.2f"%(number or 0)
return (byte[:-3] if byte.endswith('.00') else byte)+"字节"
if __name__=='__main__':
fileinfo=os.stat("message.txt")
print("文件完整路径:",os.path.abspath("message.txt"))
print("索引号:",fileinfo.st_ino)
print("设备名:",fileinfo.st_dev)
print("文件大小:",formatByte(fileinfo.st_size))
print("最后一次访问时间:",formatTime(fileinfo.st_atime))
print("最后一次修改时间:",formatTime(fileinfo.st_mtime))
print("最后一次状态变化时间:",formatTime(fileinfo.st_ctime))
实战1、根据当前时间创建文件
import time
def create():
global name
localTime=time.strftime("%Y%m%d%H%M%S",time.localtime())
name=localTime+'.txt'
with open(name,'a') as file:
pass
if __name__=='__main__':
amount=int(input("请输入需要生成的文件数:"))
for i in range(amount):
create()
print("file"+str(i+1)+":"+name)
time.sleep(1)
print("生成文件成功！")
实战2、批量添加文件夹
import os
path = "C:\\test"
number = int(input("请输入需要生成的文件夹个数:"))
for i in range(number):
ml = str(i+1)
os.makedirs(path + "\\" + ml)
print("文件夹 " + ml + " 创建成功！")
