Problem Formulation Python has special “escape characters” that start with the single backslash such as \n, \t, and \”. If you print a string with escape characters, Python prints the special meaning—for example, a new line for the newline character \n. You can see that the output prints the special meaning of the escape characters: … Read more

Learn to solve The Power of Two Interview Question In Python in this article.
Syntax numpy.all(a, axis=None, out=None, keepdims=<no value>, *, where=<no value>) Argument Type Description a array_like Input array axis None, int, or tuple of int Optional. One axis or multiple axes along which logical AND should be performed. Per default, it computes logical AND on the flat array. If this is a tuple of integers, calculates logical … Read more
Problem Formulation In Python’s interactive mode, each line is assumed to be an expression that is evaluated. The return value is provided to the user. Thus, if you evaluate a string expression or call a function or an operation that returns a string, the output will display quotes around the string to tell the user … Read more
To carry on from our introduction to Newspaper3k, we can now take our basic knowledge and realize the possibilities of what we can do with this library. Here I’m going to demonstrate for you a project which takes articles from a set of different news agencies, picks out the most used words from them, and … Read more
When it comes to developing web applications in Python there are lots of frameworks. Some examples are Pyramid, Web2Py, Bottle or CherryPy, among others. However, the two most popular ones are Flask and Django. We can confirm this fact by having a look at the most starred Python libraries in GitHub: As we will see … Read more
Problem Formulation In some shell environments, when printing a large NumPy array, the Python interpreter automatically displays only a small, truncated portion of the array, using the triple dots ‘…’ to indicate that some values are missing in the textual representation of the array. Here’s an example of a truncated array: Here’s how that looks … Read more
Problem Formulation Given a floating point number x = 123.456. How to print the number without decimal remainder? Solution 1: int() Python’s built-in function int(x) converts any float number x to an integer by truncating it towards 0. For example, positive int(1.999) will be truncated to 1 and negative int(-1.999) to -1. To boost your … Read more
Problem Formulation If you print a float value in Python that is smaller than 0.0001, Python will use the scientific notation for small numbers such as 1e-05 that is short for 1*1/10**-5. Here’s an example output when printing smaller and smaller floats to the shell. If there are more than three zeros after the decimal … Read more
Parentheses are used to initiate a function call in Python. Here are three examples: f() calls custom function f without an argument, print(‘hello world’) calls built-in function print with the string argument ‘hello world’, and range(2, 10, 3) calls built-in function range on the integer arguments 2, 10, and 3. A common question among Python … Read more
Andrews curves are used to identify structure in a multi-dimensional data set. By reducing complex data to a two-dimensional graph, we can more easily identify variables in the data that are associated, form clusters, or are outliers. We’ll show you how to plot such graphs, but before we get to that, let’s ensure every reader … Read more
