Python - How to give values to different functions


Python - How to give values to different functions

wish of those help I have been trying to send values between each function. I have created a code: , If you change def testscript(thread, i): to
code :
def testscript(thread, i=""): 
threading.Thread(target=testscript, args=(new_thread)).start() # when testscript receives this, it will just default i="" and pass that to filter
if any(check_all(sentence, word.split('+')) for word in positive_keywords):

Hope that helps My answer is probably off point, because your question was for help debugging your current implementation.
That said, if you're interested in using ready-made optimisers in Python then have a look at OpenOpt. The library contains reasonably performant implementations of optimisers for a wide variety of optimisation problems.

I wish did fix the issue. Take a look at the documentation for the math.tan function in Python:
code :
math.tan(math.radians(ang))

I wish this help you The problem is the pow function to a np.uint8 array. First, lets have a simple example:
code :
>> a = np.arange(20, dtype=np.uint8).reshape(4,5)
array([[ 0,  1,  2,  3,  4],
       [ 5,  6,  7,  8,  9],
       [10, 11, 12, 13, 14],
       [15, 16, 17, 18, 19]], dtype=uint8)
>> np.power(a,2)
array([[  0,   1,   4,   9,  16],
       [ 25,  36,  49,  64,  81],
       [100, 121, 144, 169, 196],
       [225,   0,  33,  68, 105]], dtype=uint8)

>> pow(a,2)
array([[  0,   1,   4,   9,  16],
       [ 25,  36,  49,  64,  81],
       [100, 121, 144, 169, 196],
       [225,   0,  33,  68, 105]], dtype=uint8)
b = np.float32(b) #same for g and r or to the whole image
# or this
b, g, r = cv2.split(np.float32(img))

should help you out You're confusing a bunch of programming concepts:
Don't declare a function whenever you only need a statement You're confusing function declaration with function call (invocation), and also the nesting is pointless. Declaring nested fn2 inside of fn1 doesn't magically also call fn2 and also transmit its return-value back to fn1. You still have to use an explicit return-statement from each fn.(If you forget that, you're implicitly returning None, which is almost surely not what you want) For now, just don't ever nest functions at all. Functions with no arguments are essentially useless, they can't take inputs and compute a result. Figure out what their arguments should be.
