遍歷Python程序

Question

我想要做這樣的事情的所有方法：

def a(): 
    # do stuff 
    return stuff 

def b(): 
    # do stuff 
    return different_stuff 

def c(): 
    # do one last thing 
    return 200 

for func in this_file: 
    print func_name 
    print func_return_value 

我基本上是想模仿這種瓶的應用程序，而無需將燒瓶部分：

app = Flask(__name__) 
app.register_blueprint(my_bp, url_prefix='/test') 
my_bp.data = fake_data 

def tests(): 
    with app.test_client() as c: 
    for rule in app.url_map.iter_rules(): 
     if len(rule.arguments) == 0 and 'GET' in rule.methods: 
     resp = c.get(rule.rule) 
     log.debug(resp) 
     log.debug(resp.data) 

這是可能的？

Answer 1

像這樣：

import sys 

# some functions... 
def a(): 
    return 'a' 

def b(): 
    return 'b' 

def c(): 
    return 'c' 

# get the module object for this file  
module = sys.modules[__name__] 

# get a list of the names that are in this module 
for name in dir(module): 
    # get the Python object from this module with the given name 
    obj = getattr(module, name) 
    # ...and if it's callable (a function), call it. 
    if callable(obj): 
     print obj() 

運行這給：

bgporter@varese ~/temp:python moduleTest.py 
a 
b 
c 

注意，功能不一定會在定義的順序，因爲他們被稱爲在這裏。

Answer 2

可能：

def a(): return 1 
def b(): return 2 
def c(): return 3 

for f in globals().values(): 
    if callable (f): continue 
    print f.__name__ 
    print f() 

Answer 3

使用此代碼來創建Python模塊get_module_attrs.py

import sys 
module = __import__(sys.argv[1]) 
for name in dir(module): 
    obj = getattr(module, name) 
    if callable(obj): 
     print obj.__name__ 

然後，你可以把它作爲$python get_module_attrs.py <name_of_module>

享受它！
