Parentheses are used to enclose expressions or parameters, while brackets are used to enclose arrays or indexes. Parentheses are typically used for arithmetic and function calls, while brackets are used for data structures. How do I use brackets in Python?
We can prove that to ourselves by passing that object to Python's built-intypefunction: >>>type(colors)<class 'list'> Lists are ordered collections of things. We can create a new list by usingsquare brackets([]), and inside those square brackets, we puteach of the itemsthat we'd lik...
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...

Python provides enhanced readability. For that purpose, uniform indents are used to delimit blocks of statements instead of curly brackets, like in many languages such as C, C++, and Java. Python is free and distributed as open-source software. A large programming community is actively involved ...
Round brackets are used to write tulles. Python Tuple consists of a collection separated by commas. A tuple can be compared to a list for its indexing, repetition, and nested objects. However, unlike lists that are mutable, a Tuple is immutable. Creating Tuples in Python To create a tuple...
In the previous section, you learned about using range() in a for loop, which leads to lazy evaluation of the integers represented by the range object. There are other expressions in Python that lead to lazy evaluation. In this section, you’ll explore the main ones....
