TypeError: 'numpy.float64' object is not iterable when use of write.()

Question

I've this error message TypeError: 'numpy.float64' object is not iterable when y execute my .py.

It occur in:

file=open("results.txt","a")
    for i in ConcatRPH:
        for j in i :
        file.write(j)
    file.write("\n")
file.close()

ConcatRPH is a large array about 2 million line by 3 column which containt floats like -0.00161894927736417and i need to write them in a txt file. I don't know why I have this error ... Do you have any idea ?

Are you sure that you've got the indentation correct? And perhaps [this](https://stackoverflow.com/questions/9565426/saving-numpy-array-to-txt-file-row-wise) post discusses what you want. — J...S, Mar 13 '19 at 10:36

The only possible reason is that ConcatRPH does not have the shape you think it has. So, most likely, the i you get from for i in ConcatRPH is a float, and you get an error on the following line. Print i to make sure.

However, if you really want to store a table to a text file (not doing it for practice), better use numpy.savetxt.

Great ! It work with the numpy.savetxt. Thank you blue_note – Arnaud Mar 13 '19 at 11:45
