Question

我正在juypternotebook中创建一个txt文件

%%writefile test.txt
hello this is my first line
hello this is my second line

之后，当我通过编写代码在该txt文件中添加一些行时

with open ('test.txt' ,mode = 'r') as f:

然后出现此错误

File "<ipython-input-9-e008d94f1356>", line 1
    with open ('test.txt' ,mode = 'r') as f:
                                            ^
SyntaxError: unexpected EOF while parsing

请告诉我为什么

Answer 1

您不能启动with语句（或任何块）并仅在此处结束脚本，该块中至少需要一个命令。

如果您不想添加命令，请使用pass作为占位符。

with open ('test.txt' ,mode = 'r') as f:
    pass

我一次又一次收到此错误，请告诉我为什么
