Hi everyone,
I cannot proceed from this page in the Histogram module:
https://www.codecademy.com/paths/data-science/tracks/dscp-summary-statistics/modules/dscp-distributions/lessons/intro-to-histograms/exercises/numpy-histograms
It stops with an error message of “page unresponsive”. A screenshot is below. I have tried it in the past three days, and it’s not a matter of downtime on the Codeacademy website.

Hi there, I am having this same problem. @codecademy , please assist? Thank you!
Why can a range( ) object not be used as the range argument in np.histogram( values, range, bins) ?
This causes an error:
times_hist = np.histogram(times_np, range = range(0,24), bins=4)
This causes an error too:
times_hist = np.histogram(times_np, range(0,24), bins=4)
This works:
times_hist = np.histogram(times_np, range = (0,24), bins=4)
Can someone explain the argument ‘range’ and how it works on the back end?
Documentation is almost always a great place to explore details such as parameters, return values, examples, special remarks etc.
Documentation: numpy.histogram — NumPy v1.24 Manual
As you can see, range
is one of the optional named parameters of histogram
. It has a default value of None
. If we choose to provide an argument for this parameter, it must be in the form (float, float)
.

In this case, it is one of the named parameters and should not be confused with Python’s range
sequence type (Built-in Types — Python 3.11.3 documentation)
