Shell 调用 Python 脚本常用方法

普通调用

Python 脚本示例

# -*- coding: utf-8 -*-
import datetime

if __name__=='__main__':
    today = datetime.datetime.today()
    yesterday = today - datetime.timedelta(days=1)
    keyWord = yesterday.strftime( '%Y-%m-%d' )
    print(keyWord +" 测试！")

Shell 脚本示例

#! /bin/bash


thispath=$(cd "$(dirname "$0")"; pwd)

pyfile="$thispath/test.py"
result=`python $pyfile`
echo $result >> $thispath/out.log

调用结果

$ ./runAlarm.sh
2021-05-24 测试！

带参数调用

Python 脚本示例

# -*- coding: utf-8 -*-
import sys

if __name__=='__main__':
    print("param one:"+sys.argv[1])
    print("param two:"+sys.argv[2])

运行脚本：

$ python test0.py  a b
param one:a
param two:b

Shell 脚本示例

#! /bin/bash

thispath=$(cd "$(dirname "$0")"; pwd)

pyfile="$thispath/test0.py"
result=`python $pyfile ttt ccc`
echo $result

运行结果：

param one:ttt param two:ccc

向 Shell 脚本传递参数：

#! /bin/bash

thispath=$(cd "$(dirname "$0")"; pwd)

pyfile="$thispath/test0.py"
result=`python $pyfile $1 $2`
echo $result

运行结果：

$ bash test0.sh aaa bbb
param one:aaa param two:bbb
