Python demo之文件读写操作
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.
