How to Use the Numpy Linspace Function

A visual representation of the output of np.arange(start = 0, stop = 100, num = 5).

The NumPy linspace function (sometimes called np.linspace) is a tool in Python for creating numeric sequences. It’s somewhat similar to the NumPy arange function, in that it creates sequences of evenly spaced numbers structured as a NumPy array. There are some differences though. Moreover, some people find the linspace function to be a little tricky … Read more

How to Use the Numpy Arange Function

A NumPy array of floats from 1 to 4, made with np.arange.

The Numpy arange function (sometimes called np.arange) is a tool for creating numeric sequences in Python. If you’re learning data science in Python, the Numpy toolkit is important. The NumPy arange function is particularly important because it’s very common; you’ll see the np.arange function in a lot of data science code. Having said that, this … Read more
