| 函數 | 描述 |
|---|---|
| iter(object[, sentinel]) | 回傳迭代器物件 |
例如我們有以下的純文字檔案，檔名為 data.txt
He who has health has hope. Liberty is the right to do everything which the laws allow. Two heads are better than one.Misery loves company. It is better to win the peace and to lose the war. God's mill grinds slow but sure. It takes all sorts to make a world.There are two sides to every question. Rome was not built in a day. Self-trust is the first secret of success. Every man has his taste. Experience is the extract of suffering. Imagination is more important than knowledge. The End
以下程式可以逐行印出 data.txt
with open("data.txt") as fp:
for line in iter(fp.readline, "The End"):
print(line)
