In this example, you use the Python equality operator (==) to compare two numbers.As a result, you get True, which is one of Python’s Boolean values.. Speaking of Boolean values, the Boolean or logical operators in Python are keywords rather than signs, as you’ll learn in the section about Boolean operators and expressions.So, instead of the odd signs like ||, &&, and ! that many other ...

2.1. Values and data types¶. A value is one of the fundamental things — like a letter or a number — that a program manipulates. The values we have seen so far are 4 (the result when we added 2 + 2), and "Hello, World!".. These values are classified into different classes, or data types: 4 is an integer, and "Hello, World!" is a string, so-called because it contains a string of letters.

In this example len is a built-in Python function that returns the number of characters in a string. We’ve previously seen the print and the type functions, so this is our third example of a function!. The evaluation of an expression produces a value, which is why expressions can appear on the right hand side of assignment statements. A value all by itself is a simple expression, and so is a ...

Variables, Expressions, and Assignments — Learning Python by doing
Each value has its own type: 42 is an integer (int in Python), 42.0 is a floating-point number (float in Python), and ‘Hello, Data Scientists!’ is a string (str in Python). The Python interpreter can tell you the type of a value: the function type takes a value as argument and returns its corresponding type.

Essential Python Expressions You Should Master
These types of expressions are used to show the relation between two entities. These entities may be an integer, floating-point number, or something else. These expressions use operators like “<, >, <=, >=, ==,!=”. Return types of these expressions are often boolean values, and hence, are also known as boolean expressions.
