How to deal with awk commas using paramiko on Django? [duplicate]

Question

stdout = session.exec_command('''find {} -name "{}*" -type f -exec stat -c "%n %y" {}<--**This is bash, not variable of format** + | awk "{ print $1" "$2 }" | grep -v word'''
.format(VARIABLE1, VARIABLE2))

I'm doing this code using paramiko 2.4 on Django 1.9.13, don't know how to deal with it, the error is:

KeyError at /get_xml/index/ ' print $1" "$2 '

UPDATED:

It doesn't crash right now, but doesn't returns anything, but if I do on bash, it's working, think there's missing something...

command = find {} -name '{}*.xml' -type f -exec stat -c '%n %y' {{}} + | awk '{{print $1, $2, $3}}' | grep -v 'word'

stdout = session.exec_command(command)

ANSWER

ssh.connect(hostname=VARIABLE1, username=VARIABLE2)
command = "find {} -name '{}*.xml' -type f -exec stat -c '%n %y' {{}} + | awk '{{print $1, $2, $3}}' | grep -v WHATIDONTWANTTO".format(VARIABLE3, WHATIWANTTOSEARCH)
_, stdout, _ = ssh.exec_command(command)
for item in stdout:
     #do whatever with items
     pass

finally it works, the last way was with session = ssh.get_transport().open_session() but it always retrieve 'Nonetype'

updated, it belongs to bash command, is NOT a variable from python — M. Mariscal

awk "{ print $1,$2 }" <file_name>. where is your file name here ? — Muthuraj S

That awk won't work, due to the double quotes. Change it to awk '{print $1 " " $2}' or even simpler, awk '{print $1, $2}' — PM 2Ring

In addition to the curly brace problem, you can't use double quotes inside a double-quoted string. Your Awk script should probably be single-quoted instead. (Also, avoid the useless use of grep; or, better yet, do the output filtering in Python.) — tripleee

As per documentation on .format, if you need to include a brace character in the literal text, it can be escaped by doubling: {{ and }}.

So this -exec stat -c "%n %y" {} should be -exec stat -c "%n %y" {{}} and so on, if I understood your comment correctly.
