比较操作运算符(比较运算符),又称为关系运算符(relational operators): Python逻辑运算符 注意这些值当做False对待: "", '', ''',""", set(), { } , [ ] , ( ), 0, 0.0, Python语言支持逻辑运算符,以下假设变量 a 为 1, b为 2: Python中if 语句的一般形式如下所示: ifcondition_1: statement_...
Python conditional statements: In this tutorial, we are going to learn about the conditional statements (if, if...else, if...elif...else, and nested if) with examples.
you must have noticed one thing: the conditional statements. In the examples in which we dealt with these operators, the operators were absorbed inside"if ", "else-if" and other conditional statements in python. These are called conditional statements because they represent...
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....
Python Conditional Statements If Else in Python If Elif Else Python Nested If in Python Shorthand If and If else in Python Python IF-ELSE Statements Like other popular programming languages, there are some control flow statements in Python as well. Control flow refers to the order in which the...

Python if else Conditional OperatorJust like other programming languages, Python also provides the feature to evaluate conditional statements using the conditional operator.In this tutorial, we will see the if else conational operator.if else conditional operator is used to evaluate/get either value/...

Boolean logic is at the heart of Python and most programming languages. It allows programmers to make comparisons, execute conditional statements, and implement common algorithms. The “greater than” (>) and “equals to” (==) symbols are examples of Python comparison operators, while and and ...
