我有一个Python函数，我想找到最慢的地方。我没有使用cProfile，但我还有其他功能。
我不想将我的功能分成十几个子功能：它看起来有点笨重而烦人。
是否有办法逐行分析功能？或者在我要描述执行时间的每个代码块之前和之后添加timer_start(timer_id)和timer_stop(timer_id)之类的内容？
答案 0 :(得分：0)
如果你还没有使用IPython，你应该看看。它具有像import Tkinter, Tkconstants, tkFileDialog
filename = 'no-file'
class TkApp(Tkinter.Frame):
def __init__(self, root):
Tkinter.Frame.__init__(self, root)
# options for buttons
button_opt = {'fill': Tkconstants.BOTH, 'padx': 5, 'pady': 5}
# define buttons
Tkinter.Button(self, text='Open File', command=self.askopenfilename).pack(**button_opt)
Tkinter.Button(self, text='Print File Path', command=self.printing(filename)).pack(**button_opt)
Tkinter.Button(self, text='Quit', command=self.quit).pack(**button_opt)
# define options for opening or saving a file
self.file_opt = options = {}
options['defaultextension'] = '.twb'
options['filetypes'] = [('All', '*')]
options['initialdir'] = 'C:\\'
options['parent'] = root
options['title'] = 'Select a File'
def askopenfilename(self):
"""Returns an opened file in read mode.
This time the dialog just returns a filename and the file is opened by your own code.
"""
global filename
# get filename
filename = tkFileDialog.askopenfilename(**self.file_opt)
# open file on your own
if filename:
print "askopenfilename value: " + filename
return filename
def printing(self, stringToPrint):
print "Value on click: " + stringToPrint
def quit(self):
root.destroy()
if __name__=='__main__':
root = Tkinter.Tk()
root.title("Path Printer")
TkApp(root).pack()
root.mainloop()
这样的神奇功能，可以轻松进行逐行分析。看看Timing and Profiling in IPython
