Python：用一行简单的代码读取文件中的下一行

正如标题所说，我想使用一个简单的命令让Python读取文本文件的下一行。
例如，类似这样的事情：

users = open("C:\\Users\\Tharix\\Desktop\\test.txt",mode="r")
line = test.readline(20)
print(line)
line.next() #Or something similar
print(line)

（注：我不知道这有什么帮助，但我使用的是Python的3.3.2版）

谢谢：）

只需在文件对象上迭代：

with open("C:\\Users\\Tharix\\Desktop\\test.txt", mode="r") as users:
    for line in users:
       print(line)

---

请注意，py3.x中的

iter.next（）

已重命名为

iter.\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

with open("C:\\Users\\Tharix\\Desktop\\test.txt", mode="r") as users:
    for line in users:
       print(line)

请注意，
iter.next（）
在py3.x中被重命名为
iter.\uuuuuuuuuuuu next（）
，或者最好使用
next（iter）
（这在py2.7和py3.x中都有效）
，还有一件事，如果您要尝试调用
foointerator.\uuuuuuuuuuuuuuuuuuuu next（）
您自己，实际上需要将其编写为
foointerator.\uuuuuuuuuu next（）
，因为前缀
\uuuu
所调用的名称混乱的工作方式。@hcwhsa这不是我的确切意思，Edit:Nevermind，明白了
a=iter（“hello”）；a、 \uuuu next\uuuuu（）
适合我。只有当属性以
\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu
