The with statement is a replacement for commonly used try/finally error-handling statements. A common example of using the with statement is opening a file. To open and write to a file in Python, you can use the with statement as follows:with open("example.txt", "w") as file: file....

To ensure that assumptions hold true, we rely on assertion statements. These assertions are our way of stating, “I believe this condition should be true at this point in the code.” But what happens when these assumptions are not met? This is where assertion errors come into play. 3.1 Lo...
A compile unit in an interactive environment like IPython consists of a single statement, whereas it consists of the entire module in case of modules. a, b = "wtf!", "wtf!" is single statement, whereas a = "wtf!"; b = "wtf!" are two statements in a single line. This explains wh...
Finally, you may wonder what code should go into the conditional code block. The Python documentation offers clear guidance about the idiomatic usage of the name-main idiom in that regard: Putting as few statements as possible in the block belowif __name___ == '__main__'can improve code...
Start Quiz - "Python Basics" Understanding the 'continue' Statement in Python One of the key features of Python - a dynamic, high-level programming language, is the control flow statements, among which the 'continue' statement exists. The continue statement is a powerful tool which helps to ...
Tokens in Python are the smallest unit in the program that represents a keyword, operator, identifier, or literal. Know the types of tokens and tokenizing elements.
If it evaluates to False, the code block will be ignored, and the program will continue to the statements following the 'if' block. Practical Example Here's an example to illustrate this. Let's say we have a variable x that we are uncertain about - for instance, we don't know if ...
Why would you use 'if __name__ == '__main__''? Like other programming languages, Python too has an execution entry point i.e. main. A module is a file containing Python definitions and statements
Note:The mere act of importing a package or module triggers the compilation. You can have unused import statements in your code, and Python will still compile them! What if Python has already compiled your module into a.pycfile, but you decide to modify its source code in the original.py...
