10-2 可使用方法replace()将字符串中的特定单词都替换为另一个单词。
读取你刚创建的文件learning_python.txt 中的每一行,将其中的Python 都替换为另一门语言的名称,如C。将修改后的各行都打印到屏幕上。
learning_python.txt文件内容如下:
1 In Python you can Handle file 2 In Python you can Automatic operation and maintenance 3 In Python you can make AI
编写Python代码:
1 filename='learning_python.txt' 2 with open(filename) as file_object: 3 lines = file_object.readlines() 4 for line in lines: 5 print(line.replace('Python', 'C'))
执行结果:
1 In C you can Handle file 2 3 In C you can Automatic operation and maintenance 4 5 In C you can make AI
