Python code to count values in a certain range in a NumPy array# Import numpy import numpy as np # Creating a numpy array arr = np.array([10,2003,30,134,78,33,45,5,624,150,23,67,54,11]) # Display original array print("Original Array:\n",arr,"\n") # Counting all the ...
In Python, NumPy is a powerful library for numerical computing, including support for logarithmic operations. The numpy.log() function is used to compute the natural logarithm element-wise on a NumPy array. To compute the natural logarithm of x where x, such that all the elements of the give...
Convert in NumPy Arrays If you’re working with NumPy arrays, you can convert all float elements to integers: import numpy as np float_array = np.array([1.5, 2.7, 3.9]) int_array = float_array.astype(int) print(int_array) # Output: [1 2 3] ...
You can also create a categorical histogram using thehistogram()function. You can define values in the categorical array like some names etc., and you have to give each categorical variable a value that will be shown as height in the histogram. For example, let’s create a histogram of thr...
