Python demo之文件读写操作

q66262

　　文件读写比较简单，这里就是起一个mark的作用。突出read 和readlines的区别。后者读到一个list中，前者直接读到全部内容。区别还是看一个demo：
　　


outfile = open("lxyfiledemo.txt","w")
outfile.write("hello,this is just a test for writing file in python")
outfile.write("\n")
outfile.write("hi over")
outfile.close()
infile = open("lxyfiledemo.txt")
content = infile.read()
infile.close()
print(content)

infile2 = open("lxyfiledemo.txt")
infile2.seek(0)
infile2contentList = infile2.readlines()
infile2.close()
print(infile2contentList)

　　输出为：
　　

　　hello,this is just a test for writing file in python
　　hi over
　　['hello,this is just a test for writing file in python\n', 'hi over']
　　说明：以上结果可以看到，read读到全部内容然后输出。
　　readlines读进一个list然后打印这个list.
