Pythonic way of retry running a function [duplicate]

Answer 1

Here's a generalized decorator that lets you specify the number of retries and also the exception type to ignore:

from functools import wraps
def retry(count=5, exc_type=Exception):
    def decorator(func):
        @wraps(func):
        def result(*args, **kwargs):
            for _ in range(count):
                try:
                    return func(*args, **kwargs)
                except exc_type:
                    pass
                raise
         return result
     return decorator

Use it like this:

@retry(count=10, exc_type=IOError)
def read_file():
    pass # do something
