Running this code will generate the following output in the console: Some programming languages have different data types for single characters and for multi-character strings. Although Python doesn’t have a separate data type for individual characters, internally a string is stored as an array of...

x = np.array([_ for _ in range(1000)]) This works, but its performance is hidebound by the time it takes for Python to create a list, and for NumPy to convert that list into an array. By contrast, we can do the same thing far more efficiently inside NumPy itself: x = np.ar...
For instance, the %s specifier is used as a placeholder for string variables. Similarly, the %d specifier is used as a placeholder for the integers. If we pass an integer at the place of the string variable or a string in place of the integer, the program will run into a TypeError exce...
