1. from goto import *。注意暂时不支持import goto,不是不能实现,是暂时没时间写。 2.对需要使用goto的函数,前面加个@patch 3.用label(x)和goto(x)的形式写label和goto。x可以是数字或字符串。 goto模块的代码如下: goto.py import dis,pdb #dummy functions serving as target of bytecode patching def ...

每次运行print_a_line时,你都会传入一个变量current_line。写出每个函数调用中current_line等于什么,并跟踪它如何变成print_a_line中的line_count。 找到每个函数被使用的地方,并检查其def以确保你给出了正确的参数。 在线研究file的seek函数是做什么的。尝试pydoc file,看看能否从中弄清楚。然后尝试pydoc file.seek...
