Python相当于IDL的日志函数？

Question

我正试图在python（或ipython）中找到idl日志的等效函数。我知道ipython有%logstart函数，但它只记录ipython中的输入/输出，所以如果我运行脚本，它要求我输入值，这些值就不会进入日志。为了清楚地表明，当我运行EELTnoM6.py脚本时，这里是我的终端：

In [11]: run EELTnoM6
################################################################
##             STOKES vector after the system                 ##
################################################################ 
== Demodulation matrix ==
Automatic:                A
ZIMPOL/EELT:              Z
EELT IF                   Eif
Custom                    C
Demodulation matrix?: C
Efficiency of the detector?: 1.
Demodulation matrix? (e.g. [ [1.,0.],[0.,1.] ]): [[1/6.,1/6.,1/6.,1/6.,1/6.,1/6.],     [0.5,-0.5,0.,0.,0.,0.],[0.,0.,-0.5,0.5,0.,0.],[0.,0.,0.,0.,-0.5,0.5]]
ModelStokesMeasurement time =  65.6509261131
Simulation time =  151.731481075

这是我在日志中得到的：

# IPython log file
%logstart -o -r EELTnoM6_log rotate
ls
%logstop
run EELTnoM6
%logoff

我想在日志中存储脚本请求时我给出的输入，即

Demodulation matrix?: C 
Efficiency of the detector?: 1.
Demodulation matrix? (e.g. [ [1.,0.],[0.,1.] ]): [[1/6.,1/6.,1/6.,1/6.,1/6.,1/6.],[0.5,-0.5,0.,0.,0.,0.],[0.,0.,-0.5,0.5,0.,0.],[0.,0.,0.,0.,-0.5,0.5]]

所以C，1。并且矩阵能够以相同的值再次运行它。这在IDl中非常容易，所以当我在ipython中找不到相同的东西时，我感到非常惊讶。。。

我认为您只想使用日志记录功能。它非常棒，可以很好地处理多线程。

import logging
log_file = 'journal.log' # Specify path to your log file
log_format = '[%(asctime)s] %(levelname)s: %(message)s'  # How the output is displayed
log_date_fmt = '%m/%d/%Y %I:%M:%S %p'  # How the asctime is displayed
logging.basicConfig(filename=log_file, level='DEBUG', filemode='w', format=log_format, datefmt=log_date_fmt)  # Fire up the logger
logging.info('Logger initialized')  # There are DEBUG, INFO, WARNING, ERROR levels
def journal(msg):
    ans = raw_input(msg)  # Get your user input
    logging.debug(msg + ans)  # Choosing to put it as DEBUG category
    return ans
ans = journal('Demodulation matrix?: ')  # From your example

给出输出（包含在./journal.log:中
