Malformed Lambda proxy response - Python

I know this is a duplicate of multiple questions, but for some reason I've not been able to figure out how to apply those solutions to my problem. The function works fine in Lambda tests, but fails when testing it via API Gateway.
import boto3
import json
import decimal
from boto3.dynamodb.conditions import Key, Attr
def lambda_handler(event, context):
dynamodb = boto3.resource('dynamodb')
table = dynamodb.Table('some_table')
result = table.scan()
response = {
"status code": 200,
"body": result["Items"]
}
return response
Here's the error log

I've read multiple posts talking about the response body needing to be a string and to follow some kind of predefined format, but I'm not sure what I'm missing. Any help would be greatly appreciated.

It's statusCode. And you should return a string for body.
Here you go:
import json
response = {
"statusCode": 200,
"body": json.dumps(result["Items"])
}

create java jar in lambda function using python

I am trying to create java jar with the files in AWS S3 by Lambda function using Python
I have tried in both ways
import os
def lambda_handler(event, context):
os.system('jar cf abc.jar, file1.txt, file2.txt')
return "Success"
and
import subprocess
def lambda_handler(event, context):
subprocess.call('jar cf abc.jar, file1.txt, file2.txt')
return "Success"

Remove commas
import subprocess
subprocess.call('jar cf abc.jar *.py')
# import os
# os.system('jar cf abc.jar *.py')
print("Done")
Output :
Done
Process finished with exit code 0
Verifying :
import subprocess
subprocess.call('jar tvf abc.jar')
# import os
# os.system('jar tvf abc.jar')
Output :

Python gzip gives null bytes

I'm trying to parse some log files in Python, but my responses always return only null bytes.

I've tried explicitly setting 'mode' to either 'r' or 'rb', with no difference in result.
I've also tried subprocess.Popen(['zcat', filename], stdout=subprocess.PIPE).stdout.read(), with the same response.
Perhaps relevantly, when I tried to zcat the file to another file, the output was a binary file:
$ zcat Events.log.gz > /tmp/logoutput
$ less /tmp/logoutput
"/tmp/logoutput" may be a binary file. See it anyway?

and i have a function which takes the hostname as parameter and prints it out:
please enter hostname to search for: www.snafudomain.at
www.snafudomain.at UP Thu May 8 09:09:17 2014
but what i want to archive is that the following lines after the hostname are printed out until the delimiter line "-----" the function i right now looks like this:
def getChecks(self,hostname):
re0 = "%s" % hostname
mylist = open('myhostlist', 'r')
for i in mylist:
if re.findall("^%s" % re0, str(i)):
print i
else:
continue
is there some easy way to do this? If something is unclear please comment. Thanks in advance
edit
to clarify the output should look like this:
www.mydomain.de UP Thu May 8 09:10:57 2014
HTTPS OK Thu May 8 09:10:08 2014
HTTPS-Cert OK Thu May 8 09:10:55 2014
-------------------------------------------------------------------------------------
just want to print out the lines from the searched domain name till the line with only minuses.

How about not using regex at all?
def get_checks(self, hostname):
record = False
with open('myhostlist', 'r') as file_h:
for line in file_h:
if line.startswith(hostname):
record = True
print(line)
elif line.startswith("---"):
record = False
print(line)
elif record:
print(line)

import re
def get_checks(hostname):
pattern = re.compile(r"{}.*?(?=---)".format(re.escape(hostname)), re.S)
with open("Input.txt") as in_file:
return re.search(pattern, in_file.read())
print get_checks("www.snafudomain.at").group()
This will returns all the lines starting with www.snafudomain.at till it finds ---. The pattern generated will be like this
www\.snafudomain\.at.*?(?=---)
Online Demo
We use re.escape because your hostname has . in it. Since . has special meaning in the Regular Expressions, we just want the RegEx engine to treat . as literal dot.

Order a sequence of dates as they occur in calendar year

I've got a series of pipes to convert dates in a text file into unique, human readable output and pull out MM DD. Now I would like to resort the output so that the dates display in the order in which they occur during the year. Anybody know a good technique using the standard shell or with a readily installable package on *nix?

There is a utility called sort with an option -M for sorting by month. If you have it installed, you could use that. For instance:
sort -k1 -M test.txt
-k1: First column
-M: Sort by month
Edited per twalberg's suggestion below:
sort -k1,1M -k2,2n test.txt

In two steps:
$ while read line; do date -d "$line" "+%Y%m%d"; done < file | sort -n > temp
$ while read line; do date -d "$line" "+%b %d"; done < temp > file
Firstly we convert dates to YYYYMMDD and order them:
$ while read line; do date -d "$line" "+%Y%m%d"; done < file | sort -n > temp
$ cat temp

Then we print them back to previous format %b %d:
$ while read line; do date -d "$line" "+%b %d"; done < temp > file
$ cat file
