program flow control statement

基本解釋

A compound statement consists of a flow control instruction, followed by a colon character (:), followed by a block of program statements.
一個(gè)複郃語(yǔ)句包括一個(gè)流控制指令，後跟一個(gè)冒號(hào)（:），然後再是一個(gè)程序語(yǔ)句塊。
The second type of flow control statement in Python is the while loop, which executes a block of program statements while an expression evaluates True.
Python 中的第二種流控制語(yǔ)句是 while 循環(huán)，它在一個(gè)表達(dá)式計(jì)算爲(wèi) True 時(shí)執(zhí)行一個(gè)程序語(yǔ)句塊。
