  • Reading object tree from file into Python

    - by jjkparker
    I have a Python app that contains an object structure that the user can manipulate. What I want to do is allow the user to create a file declaring how the object structure should be created. For example, I would like the user to be able to create the following file: foo.bar.baz = true x.y.z = 12 and for my app to then create that object tree automatically. What's the best way to do something like this?

  • Python shortcuts

    - by lyrae
    Python is filled with little neat shortcuts. For example: self.data = map(lambda x: list(x), data) and (although not so pretty) tuple(t[0] for t in self.result if t[0] != 'mysql' and t[0] != 'information_schema') among countless others. In the irc channel, they said "too many to know them all". I think we should list some here, as i love using these shortcuts to shorten & refctor my code. I'm sure this would benefit many.

  • Running Subprocess from Python

    - by Rohit
    I want to run a cmd exe using a python script. I have the following code: def run_command(command): p = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT) return p.communicate() then i use: run_command(r"C:\Users\user\Desktop\application\uploader.exe") this returns the option menu where i need to specify additional parameter for the cmd exe to run. So i pass additional parameters for the cmd exe to run. How do i accomplish this. I've looked at subprocess.communicate but i was unable to understand it

  • How to print source code lines in python logger

    - by anon
    Is there some relatively simple way to programmatically include source code lines to python logger report. For example... import logging def main(): something_is_not_right = True logging.basicConfig(level=logging.DEBUG, format=('%(filename)s: ' '%(levelname)s: ' '%(funcName)s(): ' '%(lineno)d:\t' '%(message)s') ) if something_is_not_right == True: logging.debug('some way to get previous line of source code here?') So that output would look like this. example.py: DEBUG: main(): 14: if something_is_not_right == True:

  • question about python sched schedular.

    - by samy
    I have read about python sched (task schedular), it works like a cron. but I have a question : lets say if i schedule a function to ryn after every 2 hours and in the mean time my system gets shut down, then I again restart the system...did the schedular automatically starts and will run the function after 2 hours? or i have to start that again after shutting down the system? did sched work like a deamon?

  • Python integer incrementing with ++

    - by Znarkus
    I've always laughed to myself when I looked back at my VB6 days, "What modern language doesn't allow incrementing with double plus signs?": number++ To my surprise I can't find anything about this in the Python docs. Must I really subject myself to number = number + 1? Doesn't people use the ++/-- notation? :-(

  • Good practice of using list of function in Python

    - by riskio
    I am pretty new to python and I discovered by myself that I can create a list of function and call with a for loop. example: def a(args): print "A" def b(args): print "B" def c(args): print "C " + str(args) functions = [a,b,c] for i in functions: i(1) So, my question is: is there any good practice or elegant way to use list of functions and what is a good use of all this? (do have a particular name the "list of functions"?) thank you

  • Python PLY zero or more occurrences of a parsing item

    - by None
    I am using Python with PLY to parse LISP-like S-Expressions and when parsing a function call there can be zero or more arguments. How can I put this into the yacc code. This is my function so far: def p_EXPR(p): '''EXPR : NUMBER | STRING | LPAREN funcname [EXPR] RPAREN''' if len(p) == 2: p[0] = p[1] else: p[0] = ("Call", p[2], p[3:-1]) I need to replace "[EXPR]" with something that allows zero or more EXPR's. How can I do this?

If i use input() or raw_input() , they would scan whole line in single variable.
