We can prove that to ourselves by passing that object to Python's built-in type function:>>> type(colors) <class 'list'> Lists are ordered collections of things.We can create a new list by using square brackets ([]), and inside those square brackets, we put each of the items that ...
Using square brackets we can get the values from tuples in Python. mytuple = ("JAVA", "Python", "Kotlin", "NodeJS") print("Value in mytuple[0] = ", mytuple[0]) print("Value in mytuple[1] = ", mytuple[1]) print("Value in mytuple[2] = ", mytuple[2]) print("Value ...
Python lazy evaluation is when Python takes the lazy option and delays working out the value returned by an expression until that value is needed.An expression in Python is a unit of code that evaluates to a value. Examples of expressions include object names, function calls, expressions with ...
In Cypher, relationships are represented as square brackets and an arrow connecting two nodes (e.g.(Node1)-[]→(Node2)). In the example, the lines containing:LIKES,:IS_FRIENDS_WITH, and:WORKS_FORrepresent the relationship between the nodes: ...

To do so you use a similar notation to indexing. To use a key to return a value, you use the same square brackets used in indexing. But, instead of specifying an index between the square brackets, with dictionaries you write the key like this:market_prices['apples']. This input returns...

One of the new features in Python 3.12 is the new type annotation syntax for generic classes, described in PEP 695. This syntax allows you to express type parameters for generic classes like list, dict, tuple, and so on using square brackets instead of parentheses. For example, instead of ...
