[英]How to put console output into .csv using Python?
我想將小波系數從控制台放到.csv行。
下面的代碼只能將一個數字放到.csv文件中
def waveletdbbiorone(self): #function for Wavelets computation
for filename in glob.iglob ('*.tif'):
imgwbior = mahotas.imread (filename) #read the image
arraywbior = numpy.array([imgwbior])#make an array for pywt module
coefwbior = pywt.wavedec(arraywbior,'db1')#compute wavelet coefficients
arr = numpy.array([coefwbior])
np.set_printoptions(threshold=3)
# print arr
for elem in arr.flat[:50]:
#print('{}\t'.format(elem)) #this code puts the result to console
with open('сomput.csv', 'wb') as csvfile:
writer = csv.writer(csvfile, delimiter=' ', quotechar='|', quoting=csv.QUOTE_MINIMAL)
writer.writerow([('{}\t'.format(elem))])
謝謝
我認為問題是你總是用w
(寫模式)打開文件,這會自動刪除內容:
嘗試這個:
with open('сomput.csv', 'wb') as csvfile:
for elem in arr.flat[:50]:
#print('{}\t'.format(elem)) #this code puts the result to console
writer = csv.writer(csvfile, delimiter=' ', quotechar='|', quoting=csv.QUOTE_MINIMAL)
writer.writerow([('{}\t'.format(elem))])
numpy.savetxt("foo.csv", array, delimiter=" ")
扁平化也有效:
numpy.savetxt("foo.csv", array.flat[:50], delimiter=" ")
