How to Find Outliers in NumPy Easily?
Can you spot the outliers in the following sequence: 000000001000000001? Detecting outliers fast can be mission critical for many applications in military, air transport, and energy production. This article shows you the most basic outlier detection algorithm: if an observed value deviates from the mean by more than the standard deviation, it is considered an … Read more
How to Split a String Into Multiple Variables Rather Than a List?
Problem Formulation Recap: The Python string.split(separator) method splits the string at a given separator and returns a split list of substrings. Per default, it uses arbitrary whitespace as a separator. Thus, if you want to store the result in a list variable, you can simply do so: However, what if you’d rather want to store … Read more
Python Get List of Values from List of Keys
Problem Formulation Given a Python dictionary d, and a list of dictionary keys. How to best determine the list of values associated to the keys? Formally, for each key in the input list, you want to add d[key] to the list of values. Here’s a minimal example: # Input: d = {‘alice’: 18, ‘bob’: 24, … Read more
How to Filter in Python using Lambda Functions?
To filter a list in Python, you can use the built-in filter() function. The first argument is the filtering condition, defined as a function. This filtering condition function is often dynamically-created using lambda functions. The second argument is the iterable to be filtered—the lambda function checks for each element in the iterable whether the element … Read more

NumPy Sort [Ultimate Guide]
The np.sort(array) function returns a sorted copy of the specified NumPy array. Per default, it sorts the values in ascending order, so np.sort([42, 2, 21]) returns the NumPy array [2 21 42]. Here’s an example of 1D sorting: And here’s an example of 2D sorting — each axis is sorted separately. An example of 3D … Read more

How to Use Slice Assignment in NumPy?
NumPy slice assignment allows you to use slicing on the left-hand side of an assignment operation to overwrite a specific subsequence of a NumPy array at once. The right side of the slice assignment operation provides the exact number of elements to replace the selected slice. For example, a[::2] = […] would overwrite every other … Read more
