How to import python variable in shell script

Question

I have a shell script like below. If I have a test.py that has a variable a=5, how can I import the variable to the following shell script?

python test.py
b=10

if [ $a == $b ]
then
   echo "a is equal to b"
else
   echo "a is not equal to b"
fi

using [ $a == $b ] is going to give you trouble you should use [[ $a == $b ]] or [ "$a" == "$b" ] and then only if $a or $b are strings. — the_velour_fog, Oct 17 '16 at 7:43

You can return a variable from your python script. Put at your python script:

a="something"
print(a)

And at your shell script:

a=$(python script.py)
b="something"

if [ "$a" == "$b" ]; then
... 
... 
...
