In the program we initialized the variablebalancewith the value of-5, which is less than 0. Since the balance met the condition of theifstatement (balance < 0), once we save and run the code, we will receive the string output. Again, if we change the balance to 0 or a positive num...
Python provides various ways to writingforloop in one line.For loopin one line code makes the program more readable and concise. You can use for loop to iterate through an iterable object or a sequence which is the simplest way to write a for loop in one line. You can use simple list ...
In Python, you can write multiple statements on the same line using a semicolon (;). However, I will not recommend this as it makes your code less readable. Further, a more common way to write multiple statements is to use multiple lines. The syntax for a multi-line statement is: x ...
Today I'm starting a new series of articles about a topic that does not get a lot of coverage: how to write Python unit tests. Unlike other testing tutorials, I'm going to focus on testing techniques more than on the testing tools themselves. The idea is that in each part of this ...
The built-in filter() function is another tool that you can use to implicitly iterate through a dictionary and filter its items according to a given condition. This tool also takes a function object and an iterable as arguments. It returns an iterator from those elements of the input iterable...
Let’s understand more use cases of If Not in Python. How to use If Not in Python to Reverse the Condition Result The main purpose of the Not operator is to reverse the original result of the boolean value(True or False), which means if the condition returns True, then the Not operato...
Python pass Statement: Syntax and SemanticsIn Python syntax, new indented blocks follow a colon character (:). There are several places where a new indented block will appear. When you start to write Python code, the most common places are after the if keyword and after the for keyword:...
Sometimes, you may need a way to allow any arbitrary exception and also want to be able to display the error or exception message. It is easily achievable using the Python exceptions. Check the below code. While testing, you can place the code inside the try block in the below example. ...
Therefore, you could instead write traditional if-else statements or even initialise a dictionary where the keys correspond to the conditions that would have been used in if/else if statements and values correspond to the desired value when that particular condition (key) holds. ...
If you’ve worked your way through some tutorials onhow to code in Python 3, and you’re comfortable with Python’s syntax, structure, and some built-infunctions, you can write Python programs that take advantage of your favorite APIs. ...
