今天我们引入另外一个程序,文件的读写
我们先把简单的程序代码贴上。然后通过我们多次的改进。希望最后可以变成一个简单的文本编辑器
以下是我们最简单的代码:
‘crudfile--读写文件‘ def readWholeFile(fileName): ‘读取整个文件‘ file = open(fileName, mode=‘r‘) text = [] for eachLine in file: print(eachLine) text.append(eachLine) return text def writeFile(fileName): ‘写文件‘ handler = open(fileName, mode=‘w‘) while True: inputText = input(‘>‘) if inputText == ‘exit‘: break else: handler.write(inputText) try: fileName = "test.txt" writeFile(fileName); textInFile = readWholeFile(fileName); except IOError as e: print(e) print(‘文件不存在‘)
