Work with 'echo' command line in Python code

Question

I attempted to utilize Python with the command line parser 'kakasi' together. Here is my code: 

# -*- coding: utf-8 -*-

import os

text = 'スッキリわかる Java入門 実践編 第2版'

cmd = "echo $text | iconv -f utf8 -t eucjp | kakasi -i euc -w | kakasi -i euc -Ha -Ka -Ja -Ea -ka"

os.system(cmd)

-------------------

The result was empty, as below:

Process finished with exit code 0

But, The result should be like below:

Help me.

Answer 1

Here, the text is a variable known to the python translator(interpreter) just; the shell you execute your order in has no clue about what $text is (it will assess to a vacant string). 

You can also try:

cmd = "echo '{}' | iconv ...".format(text)

that way you get your string to the order you need to execute. (can't test if there are different things that don't work...)
