When dealing with multiple conditions that need to be evaluated, Python’sif-elif-elsestructure is particularly useful. Theelifclause (short for “else if”) allows you to specify additional conditions to check if the initialifcondition is not met. This enables a more structured and efficient way...
When we fully execute each statement of a program, moving from the top to the bottom with each line executed in order, we are not asking the program to evaluate specific conditions. By using conditional statements, programs can determine whether certain conditions are being met and then be told...
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 ...
Python doesn’t support switch-case statements. There was a proposal to introduce Python switch case statements inPEP-3103but it was rejected because it doesn’t add too much value. We can easily implement switch-case statements logic using theif-else-elif statements. However, we can implement ...
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:...
How to Check if a Python String Contains a Substring In this quiz, you'll check your understanding of the best way to check whether a Python string contains a substring. You'll also revisit idiomatic ways to inspect the substring further, match substrings with conditions using regular expressio...
Example -1: Use of multiple conditions with logical OR The following example shows the use of the where() function with and without the optional argument. Here, the logical OR has used to define the condition. The first where() function has applied in a one-dimensional array that will retu...
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 ...
Nowadays, Python is one of the most popular and accessible programming languages. In 2019 it was ranked third in the TIOBE rating. Many experts believe that in 3-4 years it will overtake C and Java to lead the ratings. Based on this, it would not be surprising if you use Python for ...
If not, edit the comments. Comments must be up to date. If you change the code, update the comments to match the current code function. To follow the PEP-8 guide, write Python code comments in English. Choosing one language for comments ensures transferability. ...
