Python for loop else Theforloop has an optionalelsestatement which is executed when the looping has finished. for_loop_else.py #!/usr/bin/python words = ["cup", "star", "monkey", "bottle", "paper", "door"] for word in words: print(word) else: print("Finished looping") We go o...
In this section, we will see how to useif-else statementswith a loop. If-else is used when conditional iteration is needed. For example, print student names who got more than 80 percent. The if-else statement checks the condition and if the condition isTrueit executes the block of code ...
Theelseblock with theforloop, is executed, once all the elements of the list are iterated or there are no more elements left to iterate in the list. It'll be safe to say thatelsestatement is executed at the end of the loop. Although, as already mentioned in the syntax, it's complete...
Abreakstatement executed in the first suite terminates the loop without executing theelseclause’s suite. 在第一个套件中执行的break语句将终止循环,而不执行else子句的套件。 Thebreakstatement is used to terminate the execution of theforloop orwhileloop, and the control goes to the statement after t...
else: print('欢迎来到春香窑') if elif if 判断的条件: elif 判断的条件: 执行 elif 判断的条件: 执行 else: 上述不满足后执行的内容 #嵌套:Python语言里使用强制缩进来表示语句之间的结构 #pass关键字在Python里面没有意义只是单纯用来站位保证语句的完整性 ...
-Python 循环结构: 迭代执行某段语句块,有两种执行方式,一种是 while 循环,另一种是通过 for 循环 while 循环 每次循环都会先判断 test 表达式,若表达式为 True,会执行 statement1,否则跳出循环执行 statement2。 while <test>: <statements1> # test 为 True, 执行 statements1 else: <statements2> # test...
Here, the condition of the while loop is alwaysTrue. However, if the user entersend, the loop termiantes because of thebreakstatement. Pythonwhileloop with anelseclause In Python, awhileloop can have an optionalelseclause - that is executed once the loop condition isFalse. For example, ...
Python: while and else statementThere is a structural similarity between while and else statement. Both have a block of statement(s) which is only executed when the condition is true. The difference is that block belongs to if statement executes once whereas block belongs to while statement ...

while陳述句(statement)所建立的迴圈不像for迴圈,需要在一定的範圍內迭代;也不像if陳述句,只存在執行一次或不執行的狀況。只要陳述的條件為真True,while迴圈就會持續到天荒地老,或者電腦當掉。 如果你對for迴圈或if陳述句不熟悉,可以閱讀〈Python for 迴圈(loop)的基本認識與7種操作〉、〈Python if 陳述句的...
