pdb.Pdb

running under the debugger

The pdb debugger class. You create your own instance to set where commands come from and go to, modules to skip, or the backend.

Syntax

pdb.Pdb(completekey='tab', stdin=None, stdout=None, skip=None, nosigint=False, readrc=True)

Commands need not come from the keyboard: stdin=io.StringIO('n\np x\nc\n') runs a script without a person, and stdout collects the answers. By default readrc=True reads ~/.pdbrc and .pdbrc in the current directory, so a forgotten file there runs commands silently; use readrc=False for reproducible runs. skip=['json.*'] keeps it from stepping into frames of those modules.

Examples

import io, pdb
def area(w, h):
    s = w * h
    return s
out = io.StringIO()
dbg = pdb.Pdb(stdin=io.StringIO('n\np s\nc\n'), stdout=out, readrc=False, nosigint=True)
print(dbg.runcall(area, 3, 4))  # → 12
print(out.getvalue().split('(Pdb) ')[2].strip())  # → 12 — ответ на команду p s
