python 如何调用带参数的shell脚本

举例：
shell的脚本：
t.sh内容：

echo "this is a test shell with arguments"
echo "arg1 = $1; arg2 = $2;"

执行脚本./t.sh zhao
结果如下：

[noncode@gnode108 knockdown_workflow]$ ./t.sh zhao1 zhao2
this is a test shell with arguments
arg1 = zhao1; arg2 = zhao2;

python脚本：

[noncode@gnode108 knockdown_workflow]$ cat t.py
#!/usr/bin/env python
import os
import sys

def main():

print 'Hello world!'
if len(sys.argv) < 2 :
print "usage:%s config log" %(sys.argv[0])
sys.exit(1)
arg0 = sys.argv[0]
arg1 = sys.argv[1]

print "arg0 = %s; arg1 = %s" % (arg0, arg1)

print "test ./t.sh: "
os.system('./t.sh ' + arg0 + ' ' + arg1)

print "test method of replacing: "
t = 't.sh'
m = 'zhao'
n = 'zhao'
cmd = "./%s %s %s" % (t,m,n)
print "t = %s; m = %s; n = %s; cmd = %s" % (t,m,n,cmd)
os.system(cmd)

if __name__ == '__main__':
main()

运行脚本：python t.py t.sh
执行结果：

[noncode@gnode108 knockdown_workflow]$ python t.py t.sh
Hello world!
arg0 = t.py; arg1 = t.sh
test ./t.sh:
this is a test shell with arguments
arg1 = t.py; arg2 = t.sh;
test method of replacing:
t = t.sh; m = zhao; n = zhao; cmd = ./t.sh zhao zhao
this is a test shell with arguments
arg1 = zhao; arg2 = zhao;
[noncode@gnode108 knockdown_workflow]$ cat t.sh
echo "this is a test shell with arguments"
echo "arg1 = $1; arg2 = $2;"
[noncode@gnode108 knockdown_workflow]$ ./t.sh zhao1 zhao2
this is a test shell with arguments
arg1 = zhao1; arg2 = zhao2;

说明：
两种方法使用python脚本调用shell脚本：
第一种方法：

os.system('./t.sh ' + arg0 + ' ' + arg1)

注：./t.sh后面有一个空格，不同的
第二种方法：

t = 't.sh'
m = 'zhao'
n = 'zhao'
cmd = "./%s %s %s" % (t,m,n)
print "t = %s; m = %s; n = %s; cmd = %s" % (t,m,n,cmd)
os.system(cmd)

注：在之前把字符串聚合到一起。

其中连接字符串还可以使用这个方法：

t = 't.sh'
m = 'zhao'
n = 'zhao'
cmd1 = os.path.join("./", t, ' ', m, ' ', n)
print "cmd1 = %s" % cmd1

os.system('./t.sh ' + arg1)
print "replace:"
t = 't.sh'
m = 'zhao'
cmd = "./%s %s" % (t,m)
print "t = %s; m = %s; cmd = %s" % (t,m,cmd)
os.system(cmd)
