Dictionaries are a cornerstone of Python. Many aspects of the language are built around dictionaries. Modules, classes, objects, globals(), and locals() are all examples of how dictionaries are deeply wired into Python’s implementation.Here’s how the Python official documentation defines a ...

So far, we have presented a Boolean option for conditional statements, with eachifstatement evaluating to either true or false. In many cases, we will want a program that evaluates more than two possible outcomes. For this, we will use anelse ifstatement, which is written in Python aselif....
Code written in theasync/awaitstyle looks like regular synchronous code but works very differently. To understand how it works, one should be familiar with many non-trivial concepts including concurrency, parallelism, event loops, I/O multiplexing, asynchrony, cooperative multitasking and coroutines. ...
There’s no limit on how many modules you put in the templatetags package. Just keep in mind that a {% load %} statement will load tags/filters for the given Python module name, not the name of the app. To be a valid tag library, the module must contain a module-level variable nam...
Now, let’s capitalize words before joining them ifcapitalizeisTrue. Start an if statement withif capitalize:. Let’s do it in a way similar to the one we used when fixing theread_wordsfunction, except this time we’ll use a live template instead of writing the list comprehension manually...
TheelseClause in Python In some situations, when we want to run a program under thetrystatement without any error, we will use theelsestatement to complete the program processing. # pythontry:number=int(21)assertnumber%2==0except:print("It is not a even number!")else:reciprocal=1/numberpr...
Q #3) How do we add elements into an array in Python? Answer: Elements can be added into an array in many ways. The most common way is using the insert(index, element) method, where index indicates the position where we will like to insert and element is the item to insert. However...
When writing scripts in Python, there are often situations where you'll need to code the general layout of a script first, then come back to fill in the blanks later. Using thepassstatement in situations like this lets you focus on the structure by writing the code branches first and then...
The SyntaxError: multiple statements found while compiling a single statement error can be resolved by simply deleting extra statements and proceeding with only a single statement. This error can be resolved in many ways, such as: Compile one statement at a time ...
