i have function: def myfunc(): kwargs = {} = 1 b = 2 kwargs.update(a=a, b=b) newfunc(**kwargs) and newfunc def newfunc(**kwargs): print its not giving value of 1 whats wrong ? two things. first, kwargs argument in myfunc empty dict, won't pass parameters. if want pass value of a , b newfunc , can either use kwargs = {'a':1, 'b':2} newfunc(**kwargs) or newfunc(a=1, b=2) in both cases, 'a' , 'b' in kwargs dict of newfunc function. second, should extract argument kwargs dict in newfunc . print kwargs.get('a') should suffice.

i new docker, using boot2docker on windows 7. while trying configure docker build through spotify maven plugin, asked set below env variables : docker_host docker_cert_path docker_tls_verify configuration successful not sure docker_tls_verify , docker_cert_path variables ? as mentioned in readme : by default, boot2docker runs docker tls enabled . auto-generates certificates , stores them in /home/docker/.docker inside vm. boot2docker up command copy them ~/.boot2docker/certs on host machine once vm has started, , output correct values docker_cert_path , docker_tls_verify environment variables. eval "$(boot2docker shellinit)" set them correctly. we recommend against running boot2docker unencrypted docker socket security reasons, if have tools cannot switched, can disable adding docker_tls=no /var/lib/boot2docker/profile file. in more dynamic environment, boot2docker ip can change, see issue 944 .
