Append data to numpy string-CodePudding

for some reason i cant append data to a numpy string.

for b in range(len(aUnique)):
    temp = aUnique[b]
    print(temp)
    numpy.append(sGewiss, temp)
    #RawData.cell(row=b 1, column=1).value = temp

print(sGewiss)

When i print "temp" i can see the right values so the loop is working correctly but when i print the array "sGewiss" i cannot see the new values added but only the old [66830 72312 72812].

Am I using the parameters wrong? Is there a dimension issue I amnot aware of?

Thank you,

Davide

I tried to add around 100 numbers to my array "sGweiss" wich contains only 3 values. I was expecting an array containing the starting 3 elements plus the new 100 elements

CodePudding user response：

you should use :

    sGewiss = numpy.append(sGewiss, temp)

This is because NumPy append function creates a new NumPy array and returns the desired output. It does not change the input array in place.
