[英]return value from python script to shell script
I am new in Python.我是 Python 新手。 I am creating a Python script that returns a string "hello world."
我正在创建一个返回字符串“hello world”的 Python 脚本。 And I am creating a shell script.
我正在创建一个shell脚本。 I am adding a call from the shell to a Python script.
我正在添加从 shell 到 Python 脚本的调用。
This is my code:这是我的代码:
shellscript1.sh shellscript1.sh
#!/bin/bash
# script for testing
clear
echo "............script started............"
sleep 1
python python/pythonScript1.py
exit
pythonScript1.py pythonScript1.py
#!/usr/bin/python
import sys
print "Starting python script!"
try:
sys.exit('helloWorld1')
except:
sys.exit('helloWorld2')
You can't return message as exit code, only numbers.您不能将消息作为退出代码返回,只能返回数字。 In bash it can accessible via
$?
在 bash 中,它可以通过
$?
. . Also you can use
sys.argv
to access code parameters:您也可以使用
sys.argv
访问代码参数:
import sys
if sys.argv[1]=='hi':
print 'Salaam'
sys.exit(0)
in shell:在外壳中:
#!/bin/bash
# script for tesing
clear
echo "............script started............"
sleep 1
result=`python python/pythonScript1.py "hi"`
if [ "$result" == "Salaam" ]; then
echo "script return correct response"
fi
Pass command line arguments to shell script to Python like this:像这样将命令行参数传递给 shell 脚本给 Python:
python script.py $1 $2 $3
Print the return code like this:像这样打印返回码:
echo $?
