[英]Write to temp file and read from command line
I need to write a temporary file to an*x machine using python3 so that I can read it from the command line. 我需要使用python3将一个临时文件写入an * x机器,以便可以从命令行读取它。
import tempfile
import subprocess
from os import path
string = 'hi *there*'
# run markdown server-side
tfile = tempfile.NamedTemporaryFile(mode='w+', suffix='.txt', prefix='prove-math-')
tfile.write(string)
fpath = tfile.name
markdown_path = path.join(LIB_DIR, 'Markdown.pl')
command = [markdown_path, fpath]
completed_process = subprocess.run(command, check=True, stdout=subprocess.PIPE)
string = completed_process.stdout.decode()
tfile.close()
print(string)
The output should be '<p>hi <em>there</em></p>'
, but the actual output is '\\n'
, which suggests to me that Markdown.pl
read the contents of the file as '\\n'
. 输出应为'<p>hi <em>there</em></p>'
,但实际输出为'\\n'
,这向我建议Markdown.pl
将文件内容读取为'\\n'
。
Use, 采用,
file_obj.flush() file_obj.flush()
In your case, you'll have to use 就您而言,您必须使用
tfile.flush()
It'll write to the file on being called upon! 它将在被调用时写入文件!
