最近大半年都在学习python编程,在双十一的时候购买了《Python编程核心》,看到makeTextFile.py和readTextFile.py两个例子有点错误,所以在这里给修正一下! makeTextFile.py脚本: #!/usr/bin/env python#_*_coding:utf8_*_'makeTextFile.py -- create text file'importos ls=os.linesep#get filenamewhileTrue:...
file=open('text.txt','w')content=['hello world 1\n','hello world 2']file.writelines(content)file.close() 使用with…as…语句处理文件 其实一种更好(更优雅)的方式是使用with…as…的语句来处理文件,这样你不必再写close的代码手动关闭文件,它会在使用完毕后自动为你清理文件所占用的内存,只要将open...
