Running python3-3.7.3 on Slackware-14.2.
I'm trying to debug a module using pdb but failing with all attempts. For
example, using breakpoint() at the line where I want to stop the running
module and examine each line's execution, the program runs to completion and
shows there's a syntax error:
$ python3 geochem.py
File "geochem.py", line 35
boxchoices = ttk.Combobox(self, textvariable=med,
^
SyntaxError: invalid syntax
Importing pdb and inserting pdb.set_trace() produces the same output.
invoking pdb from the command line produces a full back trace:
$ python3 -m pdb geochem.py
Traceback (most recent call last):
File "/usr/lib/python3.7/pdb.py", line 1701, in main
pdb._runscript(mainpyfile)
File "/usr/lib/python3.7/pdb.py", line 1570, in _runscript
self.run(statement)
File "/usr/lib/python3.7/bdb.py", line 585, in run
exec(cmd, globals, locals)
File "<string>", line 1, in <module>
File "/home/rshepard/development/openEDMS/views/geochem.py", line 35
boxchoices = ttk.Combobox(self, textvariable=med,
^
SyntaxError: invalid syntax
I don't understand the source of the syntax error and I'm not able to allow
pdb to step through the code.
Your advice appreciated,
Rich
