在python3上使用python调试器会引发NameError：未定义名称“ raw_input”

Question

Has it changed? I am just using it as import pdb; pdb.set_trace() import pdb; pdb.set_trace() but in the line the pdb is used it throws now:

NameError: name 'raw_input' is not defined

For those asking for full traceback:

My app traceback and then:
    if not serializer.is_valid():
  vi +48  /usr/lib/python3.5/bdb.py  # trace_dispatch
    return self.dispatch_line(frame)
  vi +66  /usr/lib/python3.5/bdb.py  # dispatch_line
    self.user_line(frame)
  vi +259 /usr/lib/python3.5/pdb.py  # user_line
    self.interaction(frame, None)
  vi +346 /usr/lib/python3.5/pdb.py  # interaction
    self._cmdloop()
  vi +319 /usr/lib/python3.5/pdb.py  # _cmdloop
    self.cmdloop()
  vi +32  /home/user/.virtualenvs/myapp/lib/python3.5/site-packages/noseprogressive/wrapping.py  # cmdloop
    orig_raw_input = raw_input
NameError: name 'raw_input' is not defined

Looks very python3.5 pdb to me, nothing about 2.7 pdb

Here's the issue.

You are using noseprogressive library with 1.5.1 version which is too old around 6 years ago ( 26 Mar 2013 which is developed for Python 2.7 I guess).

https://github.com/erikrose/nose-progressive/blob/1.5.1/noseprogressive/wrapping.py#L32

They didn't handle the exception where they are assigning raw_input to a variable orig_raw_input which is why you are getting the NameError when using raw_input

---

But in the latest version 1.5.2 , they handled it properly using try and catch .

https://github.com/erikrose/nose-progressive/blob/1.5.2/noseprogressive/wrapping.py#L33

Try updating the noseprogressive library to the latest version which is 1.5.2 and it should be fine.

Hope this helps.

For Python 3.x, use input() . For Python 2.x, use raw_input() . Don't forget you can add a prompt string in your input() call to create one less print statement. input("GUESS THAT NUMBER!") here is the documentation https://docs.python.org/3/whatsnew/3.0.html
