Let’s learn how to generate evenly spaced samples in NumPy using np.linspace(), which creates arrays with a specified number of points between start and stop values. We will use Numpy linspace method for that purpose.

-
This guide shows how to calculate correlation between arrays in NumPy using np.corrcoef(), which returns the Pearson correlation coefficient matrix for two or more arrays.
-
This Python guide introduces you to calculating the absolute value using Numpy, along with several practical techniques.
-
Let’s learn how to cast NumPy array dtype using the astype() method, which converts arrays from int to float, float to int, or any other data type with simple syntax.
-
Let’s see how to generate sequence arrays in NumPy using the np.arange() function, which creates evenly spaced values with customizable start, stop, and step parameters.
-
Let’s look at a few ways to convert a numpy array to a string. We will see how to do it in both Numpy and Python-specific ways.
-
Let’s learn how to reverse array in NumPy using np.flip() for all axes, np.flipud() for vertical reversal, np.fliplr() for horizontal reversal, and slicing tricks.
-
Let’s see how to convert NumPy array to Python list using the preferred ndarray.tolist() method or the built-in list() constructor for seamless type conversion.
-
Let’s see how to create empty array in Numpy Python module.
-
Let’s see how to reshape array in NumPy using the np.reshape() method, which changes array dimensions while preserving total elements and supports order and copy parameters.
-
NumPy’s np.sqrt() function makes it easy to calculate square root in NumPy for entire arrays, applying the square root operation element-wise to 1D or multi-dimensional arrays. Let’s see how to calculate square root in Numpy Python module.
-
This guide shows how to calculate standard deviation in NumPy using np.std(), supporting both population standard deviation (default ddof=0) and sample standard deviation (ddof=1). Standard deviation is a statistical measure that quantifies the dispersion or spread of a dataset around its mean (average) value. A low standard deviation indicates that the data points tend to be close to the mean, while a high standard deviation signifies that the data points are spread out over a wider range.
-
This guide shows how to calculate variance in NumPy using the np.var() function, which handles both population variance (default) and sample variance with the ddof parameter. Variance is a key statistical measure that helps to understand how data points are spread out.
-
Let’s see how to calculate mode in Python.
-
This guide shows how to calculate geometric mean in Python using the statistics module, NumPy logarithmic method, or SciPy’s gmean function for data analysis tasks. The geometric mean is a measure of central tendency that is useful for dealing with data that has a wide range of values and is often used in finance, biology, and other fields.
