How to use python to get the name of the currently running function

This article mainly introduces pythonRelevant information about the method instance code for obtaining the current running function name, required Friends can refer to the example code of

python method to get the name of the currently running function

Abstract: How to get the source code name, function name and line number of the function in c/c++ It is very simple. FILE, FUNCTION and LINE python do not have this syntax, but it can also be obtained through a certain method. Here is an example, using exception information to obtain [possible loss of performance]

Directly paste the code [please refer to python Core Programming 4.4]

#Get the function name where the function is called (called)

#author:peterguo@vip.qq.com 
def get_func_name():
  import sys
  try:
    raise Exception
  except:
    exc_info = sys.exc_info()                             #返回 异常类型，异常，traceback对象
    traceObj = exc_info[2]                               #traceback对象
    frameObj = traceObj.tb_frame                         #获取frame对象，即本函数的frame信息
    #print frameObj.f_code.co_name,frameObj.f_lineno         #请在使用的时候将其注释
    Upframe = frameObj.f_back                           #获取该代码段的frame信息，即调用该函数的函数frame
    #print Upframe.f_code.co_name, Upframe.f_lineno          #请在使用的时候将其注释
    return (Upframe.f_code.co_name, Upframe.f_lineno)[0]      #获取名称
调用方法

Get the file name path, function name, line number

def getCurRunPosInfo():
  import sys
  try:
    raise Exception
  except:
    exc_info = sys.exc_info()    
    traceObj = exc_info[2]   
    frameObj = traceObj.tb_frame 
    #print frameObj.f_code.co_name,frameObj.f_lineno
    Upframe = frameObj.f_back            
    #print Upframe.f_code.co_name, Upframe.f_lineno 
    return (Upframe.f_code.co_filename, Upframe.f_code.co_name, Upframe.f_lineno)

#测试代码
def test1():
  print getCurRunPosInfo()

def test2():
  print get_func_name()
  
输出：
>>('demo.py', 'test1', 44)
>>test2
