This document describes the current stable version of Celery (4.2). For development docs, go here.

celery.utils.saferepr

Streaming, truncating, non-recursive version of repr().

Differences from regular repr():

• Sets are represented the Python 3 way: {1, 2} vs set([1, 2]).
• Unicode strings does not have the u' prefix, even on Python 2.
• Empty set formatted as set() (Python 3), not set([]) (Python 2).
• Longs don’t have the L suffix.

Very slow with no limits, super quick with limits.

celery.utils.saferepr.saferepr(o, maxlen=None, maxlevels=3, seen=None)

Safe version of repr().

Warning

Make sure you set the maxlen argument, or it will be very slow for recursive objects. With the maxlen set, it’s often faster than built-in repr.

celery.utils.saferepr.reprstream(stack, seen=None, maxlevels=3, level=0, isinstance=<built-in function isinstance>)

Streaming repr, yielding tokens.
