因为它的 if 语法并不像其它语言是“语句(statement)”,而是一个“表达式(expression)”,这意味着你可以直接将 if 表达式赋值给变量: 代码语言:rust AI代码解释 // 若条件为真,得到 5,否则 6letnumber=ifcondition{5}else{6}; 这种语法形式足够简单明了,不就是将大家都熟悉的“if-else”直接用于赋值么,太...
“if” statement works basically on the Boolean conditions “True” & “False.” A given block of code passes when a given “if” condition is True and does not pass or is executed when a given condition is false. “if” condition can also be used on simple mathematical conditions such ...
if (x==4) { printf("x is equal to four\n"); printf("Nothing more to do here.\n"); } printf("The if statement is now over.\n"); Python 中的相同代码如下所示:if x == 4: print "x is equal to four" print "Nothing more to do here." print "The if statement is now over...
Explanation: Here, the program checks if the age is greater than or equal to 16, prints a message if the condition is true, and does not return any output if the condition is False. 2. If…Else Statement in Python The if-else statement runs one block of code if the condition is True...
Python语言比起C++、Java等主流语言,语法更简洁,也更接近英语,对编程世界的新人还是很友好的,这也是其显著优点。最近总有人问我Python相关的问题,这些问题也偏基础,自古有句话,授人以鱼不如授人以渔,刚好趁五一时间总结了几篇Python的知识点,帮助小伙伴成功入坑Python,将这门工具语言顺利掌握起来。 Python常用数据...
In Python, one of the essential control flow statements is the if statement. The primary purpose of the if statement is to execute code conditionally. This means that certain blocks of code will only be run if a particular condition or set of conditions is met....
The equality operator (==) tests if two variables have an equal value. Given variable x=3 and y=3, we can test for equality using the statement if x == y, which will return true. If we change either x or y, it would return false. It looks like the assignment operator (=) , ...

Python当中的判断语句非常简单,并且Python不支持switch,所以即使是多个条件,我们也只能罗列if-else。 # Let's just make a variable some_var = 5 # Here is an if statement. Indentation is significant in Python! # Convention is to use four spaces, not tabs. ...
last string is not empty, so bool() will return True inside if condition. Hence statement inside the if condition is executed.6. Using == OperatorThe == operator is used to test equality between two values. It returns True if the values are equal, and False if they are not. You can...
