The with statement simplifies our work when reading files. Without with, we need to manually handle exceptions and close the resources. try_except_finally.py #!/usr/bin/python f = None try: f = open('works.txt', 'r') for line in f: print(line.rstrip()) except IOError as e: ...
一、文件读取(File reading) Python 读取文件有三种方法: read - 将文件内容读取到字符串中(一次性操作) readline - 按行读取文件(一行一行读,分布操作) readlines - 读取所有行,按行形成一个列表(一次性操作) 我们找一小段配置文件来分别演示下吧,将下面的文本保存问sw1.txt。 #interfaceGigabitEthernet0/0/1...
