print("b is not greater than a") 1. 2. 3. 4. 5. 6. 二、if…else 简写 简写If 如果只有一条语句要执行,则可以将其与if语句放在同一行。 单行if 语句: a = 200 b = 66 if a > b: print("a is greater than b") 1. 2. 3. 简写If … Else 如果只有两条语句要执行,一条用于 if,...
在Python中,以下哪个语句正确地使用了if条件语句来判断一个变量x是否大于10,并在条件为真时输出'x is greater than 10 O A. if(x>10):print("x is greater than 10" ) B. ifx>10 print(x is greater than 10) C. ifx>10:print(x is greater than 10) D. if x>10,print("x is greater ...
你也可以有一个else没有elif: a = 200b= 33ifb >a:print("b is greater than a")else:print("b is not greater than a") Short Hand If ifa > b:print("a is greater than b") Short Hand If ... Else 如果您只有一条语句要执行,一条用于 if,一条用于 else,您可以将它们全部放在同一行: ...
嵌套if语句 嵌套if语句允许我们在一个if语句块内部使用另一个if语句。这在需要进一步细分条件时非常有用。 以下是一个嵌套if语句的示例: x=10y=5ifx>5:print("x is greater than 5")ify>2:print("y is greater than 2")else:print("y is less than or equal to 2")else:print("x is less than ...
pythonx = 5if x > 10:print("x is greater than 10")elif x == 10:print("x is exactly 10")else:print("x is less than 10")在这个例子中，我们首先检查x是否大于10。如果是，则打印"x is greater than 10"。否则，我们继续检查x是否等于10。如果是，则打印"x is exactly 10"。如果这两个...

if x > y: #...(tab)print("x is greater than y") # ...elif x < z: (tab)print("x is less than z") # ..默认处理：当需要一个默认的处理分支时，可以使用else子句。例如，根据年龄判断是否成年：age = 18 if age < 18: (tab)print("未成年") else: #...(tab...
if 语句的哪个部分必须缩进? [ ] 全部 if 语句都要缩进 [√] if 里面的语句要缩进 [ ] 第一行要缩进 一个使用 if 的例子: 输出结果: 显然10 大于 5 是成立的,所以 if 内的10 greater than 5被打印出来。因为Program ended没有缩进,所以不论 if 内的语句是否被执行,都会将之输出。
condition为True,代表if判断成功,执行statement1。 condition为False,代表if判断不成功,进入else情况,执行statement2。 代码示例 >>>x =5>>>ifx >0:...print("x is greater than 0")...else:...print("x is less than or equal to 0") xisgreater than0 ...
