Today, your software runs perfectly, but if the code is written poorly, in 3-4 years, adding the simplest stuff to your app will be a massive headache. It will cost you more and take forever. Evaluate your code quality early on so that you don’t need to rewrite it entirely when you...
For example, say that you want to code a function that takes a number from 0 to 2 and return the strings "rock", "paper", or "scissors". Instead of writing the function right away, you start writing the following tests: Python test_game.py import unittest from game import rock_paper...
try: num = int(“Intellipaat”) except Exception: print(“A general exception has occurred.”) except ValueError: print(“Value Error: Trying to convert String to Number.”) Here, in this code, the ValueError exception is written after the generic Exception, so the compiler will not catch...
The error message should be specific enough to help other developers identify, diagnose, and debug the error. However, it shouldn’t reveal too many details of your code’s internals because this practice may lead to security flaws. In any case, remember that these are just recommended ...
Sentiment analysis is considered one of the most popular strategies businesses use to identify clients’ sentiments about their products or service. But what is sentiment analysis? For starters, sentiment analysis, otherwise known as opinion mining, is the technique of scanning words spoken or written...
Namespaces uniquely identify all the objects inside a program. However, these namespaces also have a scope defined for them where you could use their objects without any prefix. A few examples of scope created during code execution in Python are as follows: A local scope refers to the local ...
Code for creating and managing concurrency is being collected in a new top-level namespace, concurrent. Its first member is a futures package which provides a uniform high-level interface for managing threads and processes. The design for concurrent.futures was inspired by the java.util.concurrent...
If the environment you want to use isn't listed, you might need to manually identify an existing environment.Use virtual environmentsA virtual environment is a unique combination of a specific Python interpreter and a specific set of libraries that's different from other global and conda environme...
13. Identify Length of a Tuple Use len function as shown below to identify the number of elements in a tuple. >>> primes+names (3, 5, 7, 11, 13, 'c', 'c++', 'java', 'angular') >>> len(names+primes) 9 14. Slice a Tuple ...
1 is added to i. We increment to i = 2. After all indented code after the colon has run, the loop is executed again by returning to the while keyword. The while loop checks the condition again. 2 is less than or equal to 10. 2 is printed to the console. 1 is added to i. ...
