The break statement, like in C, breaks out of the innermost enclosing for or while loop.Python中断语句与C语言类似，打破了最小封闭for或while循环。Loop statements may have an else clause; it is executed when the loop terminates through exhaustion of the list (with for) or when the condition ...

When dealing with multiple conditions that need to be evaluated, Python’sif-elif-elsestructure is particularly useful. Theelifclause (short for “else if”) allows you to specify additional conditions to check if the initialifcondition is not met. This enables a more structured and efficient way...
