amazon web services - Running AWS CLI through Python returns a "sh: 1: aws: not found" error -

-

i trying copy file s3 bucket, using python, so:

cmd = 'aws s3 %s %s' % (filename, bucketname) os.system(cmd)

it gives me sh: 1: aws: not found error.

however, using s3cmd works fine.

why s3cmd work, not aws?

also, did which aws , returned: /home/username/anaconda/bin/aws.

which s3cmd returns: /home/username/anaconda/bin/s3cmd.

why 1 work, not other, despite having same root?

a quick way troubleshoot issue try full path on os call see if path problem:

cmd = '/path/to/aws s3 %s %s' % (filename, bucketname) os.system(cmd)

there few reasons why problem, related path variable (at first guess). however, might better steer away os.system noted in docs (https://docs.python.org/2/library/os.html#os.system) , use alternative methods.

using subprocess:

cmd = ['/path/to/aws', 's3', filename, bucketname] subprocess.popen(cmd)

or use python aws client boto3 package. there many ways, 1 quick example question (how save s3 object file using boto3):

import boto3 s3_client = boto3.client('s3') s3_client.upload_file(filename, bucketname, filename)

that 1 not testable moto, can annoying. instead if want test, can this:

import boto3 s3_resource = boto3.resource('s3')  open(filename, 'rb') f:     binary = f.read()  s3_resource.bucket(bucketname).put_object(     key=filename,     body=binary )

python - jinja2: TemplateSyntaxError: expected token ',', got 'string' -

-
i new jinja2 , having issue using python regular expression (re). in following code bold lines have error string in them. {% block content %} <div class="container"> {% l in lines %} {% if re.search(r"error", l) %} {# <<< throws error #} <b> {{ l }} </b> {% else %} {{ l }} <hr> {% endif %} {% endfor %} </div> {% endblock %} the re.search above throws following error: jinja2.exceptions.templatesyntaxerror templatesyntaxerror: expected token ',', got 'string' raw python code not supported in jinja2 template syntax. {% if re.search(r"error", l) %} replace line with {% if "error" in l %} can fix problem. if logical condition more complicated, should consider defining own custom filters (which can call python code) or complicated things in view layer. go check global namespace .

Qt4: how to send QString inside a struct via QSharedMemory -

-
i have struct struct control_data{ int column_number; qstring cell; }; i need send thread of qsharememory. read can't because qstring contains pointers inside. other ways? you have serialize struct byte array. can convert qstring const char* this: mystring.tostdstring().c_str(); but serializing qstring should work. the first step serialize struct qdatastream using qt, example here . then once struct can read , written can pass shared memory. a complete example of using qsharedmemory can found here . here relevant code: // first, test whether shared memory segment attached process. // if so, detach if (sharedmem.isattached()) { sharedmem.detach(); } ... qbuffer buffer; buffer.open( qbuffer::readwrite ); qdatastream out( &buffer ); out << youstruct; int size = buffer.size(); // size of int + size of qstring in bytes if ( !sharedmem.create( size ) ) { return; } // write shared memory sharedmem.lock(); char *to = (char*...
