将python脚本输出传递到另一个程序stdin
|
我有一个应用程序，它可以直接从终端获取输入，也可以使用管道将另一个程序的输出传递到该程序的stdin中。我想做的是使用python生成输出，以便正确设置其格式，并将其从同一脚本传递到该程序的标准输入。这是代码：
#!/usr/bin/python
import os
import subprocess
import plistlib
import sys
def appScan():
os.system(\"system_profiler -xml SPApplicationsDataType > apps.xml\")
appList = plistlib.readPlist(\"apps.xml\")
sys.stdout.write( \"Mac_App_List\\n\"
\"Delimiters=\\\"^\\\"\\n\"
\"string50 string50\\n\"
\"Name^Version\\n\")
appDict = appList[0][\'_items\']
for x in appDict:
if \'version\' in x:
print x[\'_name\'] + \"^\" + x[\'version\'] + \"^\"
else:
print x[\'_name\'] + \"^\" + \"no version found\" + \"^\"
proc = subprocess.Popen([\"/opt/altiris/notification/inventory/lib/helpers/aex- sendcustominv\",\"-t\",\"-\"], shell=False, stdin=subprocess.PIPE, stdout=subprocess.PIPE)
proc.communicate(input=appScan())
没有找到相关结果

返回，因此等效于。您需要才能返回字符串。 试试看（未测试）：def appScan(): os.system(\"system_profiler -xml SPApplicationsDataType > apps.xml\") appList = plistlib.readPlist(\"apps.xml\") output_str = \'Delimiters=\"^\"\\nstring50 string50\\nName^Version\\n\' appDict = appList[0][\'_items\'] for x in appDict: if \'version\' in x: output_str = output_str + x[\'_name\'] + \"^\" + x[\'version\'] + \"^\" else: output_str = output_str + x[\'_name\'] + \"^\" + \"no version found\" + \"^\" return output_str proc = subprocess.Popen([\"/opt/altiris/notification/inventory/lib/helpers/aex- sendcustominv\",\"-t\",\"-\"], shell=False, stdin=subprocess.PIPE, stdout=subprocess.PIPE) proc.communicate(input=appScan())
