I have been working with Flask.route() decorator for a while and wanted to write my own, but it always tells me that the function isn't passed into it.
I've copied everything exactly like in the Flask examples, so my decorator definition must be wrong:
def decorator(f, *d_args):
def function(*args, **kwargs):
print('I am decorated')
return f(*args, **kwargs)
return function
#decorator()
def test(a, b=1):
print('Test', a, b)
test(1, 6)
The error I get:
Traceback (most recent call last):
File "C:/Users/Tobi/Desktop/decorators.py", line 49, in <module>
#decorator()
TypeError: decorator() missing 1 required positional argument: 'f'
First of all, there are questions on SO which handle this problem. You should have done more research on this error before writing a new question. But anyway:
The reason for your error is because you are calling the decorator by writing it before a def because you are already calling it using the brackets decorator() without passing anything in, it throws an error.
For your decorator, the correct usage would be:
#decorator # no brackets here
def function()
...

class Solution:
def remove(self,arr,target):
if target in arr:
arr.remove(target)
remove(arr,target)
return len(arr),arr
else:
return "not in the array"
ans=Solution()
print(ans.remove([3,2,2,3],3))
This is the Error
Traceback (most recent call last):
File "c:\Users\ashut\Practice\scrap.py", line 10, in <module>
print(ans.remove([3,2,2,3],3))
File "c:\Users\ashut\Practice\scrap.py", line 5, in remove
remove(arr,target)
NameError: name 'remove' is not defined
Somehow the above program runs in google colab and I've tried restarting the runtime
You have to add the "self" tag before calling the function inside ur function.
class Solution:
def remove(self,arr,target):
if target in arr:
arr.remove(target)
self.remove(arr,target)
return len(arr),arr
else:
return "not in the array"
ans=Solution()
print(ans.remove([3,2,2,3],3))
The temp variable name is arr, is that mean Array?
If so, the code "remove(arr, target)" is no need, remove this line, is OK.

I want to call a function (my_function), where clearly in my code I am calling it but if the function is not executing.
Someone knows what this is??
Here is my code:
import pandas as pd
my_variable = "1"
if my_variable == "1":
my_function()
global my_function
def my_function():
def tryloc(df, col, idx, default=None):
try:
return df.iloc[col, idx]
except IndexError:
return default
print("hello")
edit = pd.read_csv("priv/productos.csv")
product = tryloc(edit, 1, 0)
print(product)
and the second problem is that it says that this function does not exist when I am declaring it globally
Thanks if you answer!
Despite popular belief, "it's not working" isn't adequate information to diagnose a problem. That said, you are calling the function before it is even declare. You must declare a function before it can be called, always.Try moving
myFunction();
after where you defined it. But, there is a lot more going on here that's wrong and the question doesn't explain what the desired outcome is so I'm not sure how to help. I recommend going back and checking out some python scope documents.

While testing some code, I was given an error:
TypeError: breadth_first_search() takes from 2 to 3 positional arguments but 4 were given
The parameter bit of the function declaration looks like this:
def breadth_first_search(self, id: int, level=None)
The call looks like this:
tree.breadth_first_search(parent_id)
As far as I'm aware, this should be correct. I don't know why it would interpret my one argument (or two, including self) as four. Is there something plain that I'm missing?

For completeness, here's the traceback:
Traceback (most recent call last):
File "test.py", line 4, in <module>
tree = FeatureQuery.load_feature_tree("general", inventory)
File "D:\Speechcraft\Python\core\ling_query.py", line 201, in load_feature_tree

parent = tree.breadth_first_search(parent_id)
File "D:\Speechcraft\Python\core\phonological_units.py", line 37, in breadth_first_search
return self.breadth_first_search(self, id, next_level)
TypeError: breadth_first_search() takes from 2 to 3 positional arguments but 4 were given
It turned out to be a silly mistake. I accidentally included self as a parameter in the recursive call. Thanks go to user2357112 supports monica.

The program i am working on have a class with constructor defined as follow :
def Oracle(object) :
Agold = None
sentence = None
def __init__(self, sentence, Agold):
self.Agold = Agold
self.sentence = sentence
but, when i call the constructor in my main method, as follow :
oracle = Oracle(words, ref_tree)
python 3 give me this error :
Traceback (most recent call last):
File "oracle_test.py", line 52, in test_exemple
oracle = Oracle(words, ref_tree)
TypeError: Oracle() takes 1 positional argument but 2 were given
i don't understand the origin of this problem, and i don't see what gone wrong.
Can someone give me an explanation ?
Thanks
You defined Oracle as a function instead of a class. Use class instead of def. Also, assuming Agold and sentence are supposed to be instance variables instead of class variables, Agold = None and sentence = None are not needed (see this).
class Oracle(object):
def __init__(self, sentence, Agold):
self.Agold = Agold
self.sentence = sentence

regardless of what the functions have to return, my code seems to not call the first function properly, as when I try to pass some doctest it raises the error:
File "preg3.py", line 27, in mesDivisions
if nombreDivisions(llista[0],m)>=nombreDivisions(llista[1],m):
NameError: global name 'nombreDivisions' is not defined
here is my code:
def nombreDivisons(n,m):
x=0
def aux(n,m):
if n<m:
return x
else:
if n%m==0:
x=x+1
return aux(n/m,m)
else:
return x
def mesDivisions(llista,m):
if len(llista)==1:
return llista[0],nombreDivisions(llista[0],m)
else:
if nombreDivisions(llista[0],m)>=nombreDivisions(llista[1],m):
del llista[1]
return mesDivisions(llista,m)
else:
del llista[0]
return mesDivisions(llista,m)
any ideas why?
Check your white space. You want at least one and according to pep8 two blank lines between functions.
You failure is a typo though. It should be nombreDivisions but you left out the i so it is nombreDivisons.
