Less than:a < b Less than or equal to:a <= b Greater than:a > b Greater than or equal to:a >= b These conditions can be used in several ways, most commonly in "if statements" and loops. An "if statement" is written by using theifkeyword. ...

elif(else if的缩写)允许你检查多个表达式是否为真,并在前一个条件为假时执行特定代码块。 x=10ifx>15:print("x is greater than 15")elifx>10:print("x is greater than 10 but less than or equal to 15")else:print("x is 10 or less") 在这个例子中,因为x大于 10 但不大于 15,所以第二个...

x = 5if x >= 10:print("x is greater than or equal to 10")else:print("x is less than 10") 在这个例子中,由于x的值为 5,因此会执行else语句下的代码块,输出"x is less than 10"。 语法格式 Python 中使用 if else 关键字表示条件语句. ...
eval("print('x is greater than y') if x > y else print('x is less than or equal to y')") 在这个例子中,eval函数根据条件x > y的结果执行不同的代码块,并输出相应的结果。 3、执行循环 eval函数还可以执行循环,重复执行一段代码块。例如: ...
