class SynthesisPromptGenerator:
def wait_key(self):
''' Wait for a key press on the console and return it. '''
result = None
for singlePrompt in ["questionCat", "questionDog"]:
try:
result = raw_input(singlePrompt)
print 'input is: ', result
except IOError:
pass
return result
我有一个PromptGenerator会生成多个终端提示问题,在回答第一个问题后,第二个会弹出,如
questionCat
(and wait for keyboard input)
questionDog
(and wait for keyboard input)
class PromptResponder:
def respond(self):
generator = SynthesisPromptGenerator()
child = pexpect.spawn(generator.wait_key())
child.expect("\*Cat\*")
child.sendline("yes")
child.expect("\*Dog\*")
child.sendline("no")
child.expect(pexpect.EOF)
if __name__ == "__main__":
responder = PromptResponder()
responder.respond()
Cat
,则回答yes
Dog
,则回答no
所以它来了:
我做了一些搜索,但发现大多数问题都是针对shell脚本echo yes | ./script
,而不是很多in python
非常感谢

根据评论中的建议,使用pexpect
。
请参阅pexpect on github,the official docs和this handy python for beginners walkthrough on pexpect。
举个例子。我们说这是您的x.sh
文件:
#!/bin/bash
echo -n "Continue? [Y/N]: "
read answer
if [ "$answer" != "${answer#[Yy]}" ]; then
echo -n "continuing.."
else
echo -n "exiting.."
fi
你可以这样做:
import os, sys
import pexpect
# It's probably cleaner to use an absolute path here
# I just didn't want to include my directories..
# This will run x.sh from your current directory.
child = pexpect.spawn(os.path.join(os.getcwd(),'x.sh'))
child.logfile = sys.stdout
# Note I have to escape characters here because
# expect processes regular expressions.
child.expect("Continue\? \[Y/N\]: ")
child.sendline("Y")
child.expect("continuing..")
child.expect(pexpect.EOF)
print(child.before)
python脚本的结果:
Continue? [Y/N]: Y
Y
continuing..
虽然我必须说如果你有能力编辑它,使用px脚本使用pexpect有点不合时宜。编辑脚本会更简单,以便它不再提示:
#!/bin/bash
echo -n "Continue? [Y/N]: "
answer=y
if [ "$answer" != "${answer#[Yy]}" ]; then
echo "continuing.."
else
echo "exiting.."
fi
然后您可以自由使用subprocess
来执行它。
import os
import subprocess
subprocess.call(os.path.join(os.getcwd(),"x.sh"))
或者如果您希望输出为变量:
import os
import subprocess
p = subprocess.Popen(os.path.join(os.getcwd(),"x.sh"), stdout=subprocess.PIPE)
out, error = p.communicate()
print(out)
我意识到这对你来说可能是不可能的,但值得注意。
