How to get a function name as a string in Python?
In Python, how do I get a function name as a string without calling the function?
def my_function():
pass
print get_function_name_as_string(my_function) # my_function is not in quotes
should output "my_function" .
Is this available in python? If not, any idea how to write get_function_name_as_string in Python?
my_function.__name__
Using __name__ is the preferred method as it applies uniformly. Unlike func_name , it works on built-in functions as well:
>>> import time
>>> time.time.func_name
Traceback (most recent call last):
File "<stdin>", line 1, in ?
AttributeError: 'builtin_function_or_method' object has no attribute 'func_name'
>>> time.time.__name__
'time'
Also the double underscores indicate to the reader this is a special attribute. As a bonus, classes and modules have a __name__ attribute too, so you only have remember one special name.
你也可以使用
import sys
this_function_name = sys._getframe().f_code.co_name
my_function.func_name
There are also other fun properties of functions. Type dir(func_name) to list them. func_name.func_code.co_code is the compiled function, stored as a string.
import dis
dis.dis(my_function)
will display the code in almost human readable format. :)
