छवि दर्ज करें यहाँ वर्णन मैंने उपरोक्त छवि के वेग फ़ील्ड रेखा की छानबीन करने के लिए कोड लिखा था, लेकिन किसी नतीजे के परिणामस्वरूप अंधेरे का कुल जाल हो गया है क्या कोई मुझे मदद कर सकता है? यहाँ मेरा कोड है। 

  x = linspace (-45, -15,1500) y = लिनसेपेस (-3,9,600) थर (एक्स, वाई, वीएक्स, वीजे)

वीएक्स और वीजे एचडीएफ 5 डेटा से हैं और उनके आकार हैं (600 एल, 1500 एल)। या, क्या वेक्टर क्षेत्र को छानने का एक तरीका है जब -25 से -30 से एक्स और -5 से -1 के लिए z

अंधेरे की छवि इस प्रकार है:

मैंने तब कोड की कोशिश की 

  x, y = numpy। मैशग्रीड (numpy.linspace (-45, -15,1500), numpy.linspace (-3,9,600)) तरकश (एक्स [:: 20, :: 20], y [:: 20, :: 20], वीएक्स [:: 20, :: 20], वीजे [:: 20, :: 20], रंग = 'आर', कोण = 'एक्सआई', पैमाने_अनुमति = 'एक्सआई', पैमाने = 9000000)

और छवि इस तरह दिखती है यहां छवि विवरण दर्ज करें

python - Calculate STD manually using Groupby Pandas DataFrame -

Image
I was trying to write a solution, which is a different and a manual for calculating a mean and STD The way. I have created a = ["Apple", "Banana", "Cherry", "Apple"] B = [3,4,7,3] C = [5,4,1,4] D = [7,8,3,7] Pd DF = PD to import pandals DataFrame (index = class (4), column = list ("ABCD")) DF ["A"] = A DF ["B"] = BDF ["C"] = C DF ["D"] = D Again, I made a list of A duplication. Then I went through the group all the time of the objects and calculated the solution. import as np l = list (set (df.A)) df.groupby ('A', As_index = False) listMean = [0] * len (df.C) ListSTD = [0] * L in the LAN (df.C) X: s = np.mean (df [df ['A'] == x] for C =.) = Z = [index for index, enumerate In the object (df ['a']. Value] x == item i for z: listMean [i] = s in: s = np.std (df [df ['a'] == X] .cvalues) z = index for index, enumerate item (df ['a']. Value) if x ==...
