Python - save binned data to text file

Question

I want to save some histogram data in a csv file. This is the code I came up with: ``` ExportName_csv = 'ExportData/' + FileName + '.csv' freq, bins = np.histogram(ValList,bins) np.savetxt(ExportName_csv, izip(freq, bins), delimiter="	") ``` For each bin I want to save the bin value and the corresponding count `freq` in `ExportName_csv`. I want values regarding different to be bins in different lines; in each line values are separated by a comma. With the current code I get the error `IndexError: tuple index out of range`. What do you suggest to do? Full traceback is: ``` np.savetxt(ExportName_csv, izip(freq, bins), delimiter="	") File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/nump‌​y/lib/npyio.py", line 976, in savetxt ncol = X.shape[1] IndexError: tuple index out of range ```

Accepted Answer

First, comma is `','`, not `	`.

Second, you should use `zip`, not `izip`:

```
>>> data = zip(*np.histogram(ValList,bins))
>>> np.savetxt('test.txt', data, delimeter=',')
```
