unix - Execute a python script as a command -

i'm writing python script placed in location. want execute command. ex.

$ find_branch test 

where find_branch script placed in anywhere in system.

i know how achieve this. can run on place script present chmod u+x on script , removing .py script

sudo nano /usr/bin/testpyscript 

then inside script:

#!/usr/bin/python print("i'm python script") 

give x permission:

sudo chmod +x /usr/bin/testpyscript 

now can use regular command:

bash-4.2$ testpyscript  i'm python script 

it doesn't have @ /usr/bin, location inside $path do. let's want located @ folder inside home directory, this:

pwd /home/brunorb  mkdir somedir sudo mv /usr/bin/testpyscript somedir/  export path=$path:/home/brunorb/somedir/  testpyscript # folder in system i'm python script
