Here are several examples of this type of if statement: Python >>> x = 0 >>> y = 5 >>> if x < y: # Truthy ... print('yes') ... yes >>> if y < x: # Falsy ... print('yes') ... >>> if x: # Falsy ... print('yes') ... >>> if y: # Truthy .....
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....
Conditional Statements in Python (if/elif/else)Paul Mealus02:17 Mark as Completed Supporting Material Recommended TutorialAsk a Question In this video, you’ll meet the Conditional Expression, which is some sort of one-lineif-else-statement. The basic syntax is as follows: ...
if(condition){// do this if 'condition' is true}else{// do this if 'condition' is false} where conditionis a boolean statement that evaluates to true or false. You can also use anifwithoutanelse, or follow anif(condition)withelse if(secondCondition)if you have a second condition that...
Python also allows us to use conditional expressions (or ternary operators) to evaluate the truthiness of complex statements in a single line. age = 1 is_baby = 'baby' if age < 2 else 'not a baby' This is the equivalent of the following if/else statement: age = 1 if age < 2: is...
英文: 1. When using the and operator, both sides of the statement being evaluated must > be true for the whole statement to be true. 英文: 2. When using the or operator, if either side of the comparison is true, then the >whole statement is true. ...
assertion nested under a conditional statement assertionnestedunderaconditional 在编程中，"assertionnestedunderaconditional"通常意味着在一个条件语句（如if或while语句）内部有一个断言语句。断言是一个用来测试某个条件的语句，如果该条件为真，则断言成功；如果该条件为假，则断言失败，并可能引发错误或异常。例如...
Conditional StatementsConditional statements are an important part of many programs. They allow logic control of our programs. There are three main conditional statement types in Python. If / Elif / Else conditionals, For loops and While loops.doi:10.1007/978-1-4302-6479-8_5Gregory Walters...
