A few weeks ago I was helping someone write a Python script to automate their work-flow. At one point we needed to create a string array. Since it was a while since I last coded in Python, I didn’t have the syntax memorized on how to create an array of strings. What to do? A ...
Example 3 – Creating a Variable Table Array Lastly, we’ll create a variable table array for theVLOOKUPandINDIRECTfunctions. For this purpose, we modified the dataset again and made two tables to show the sales for two months. First, we’ll set named ranges for the tables. Steps: Name t...

In many applications that use np.linspace() extensively, however, you’ll most often see it used without the first three parameters being named.You can use non-integer numbers to define the range:Python >>> np.linspace(-5.2, 7.7, 30) array([-5.2 , -4.75517241, -4.31034483, -3.86551724...
Apply np.array() method to convert a list to a numpy array: 1importnumpy as np2mylist = [1, 2, 3]3x =np.array(mylist)4x Output:array([1, 2, 3]) Or just pass in a list directly: y = np.array([4, 5, 6]) y Output:array([4, 5, 6]) ...
To create an array of random integers in Python with numpy, we use the random.randint() function. Into this random.randint() function, we specify the range of numbers that we want that the random integers can be selected from and how many integers we want. ...
To create a histogram in Python using Matplotlib, you use thehist()function. This function takes in an array-like dataset and plots a histogram. Here’s a simple example: importmatplotlib.pyplotasplt data=[1,2,2,3,3,3]plt.hist(data)plt.show()# Output:# A histogram plot with x-axis...
