In the test_nonexistent_file() method, we provide the directory path and name of a non-existent file. We use the self.assertFalse() assertion to check if the file_exists() function returns False for this file. Flowchart: For more Practice: Solve these Related Problems: Write a Python un...

1.文件基本操作: f = open('file.txt','r') #以只读方式打开一个文件,获取文件句柄,如果是读的话,r可以不写,默认就是只读, 在python2中还有file方法可以打开文件,python3中file方法已经没有了,只有open frist_line = f.readline()#获取文件的第一行内容,返回的是一个list print(frist_line)#打印第一行...
