Question

以下代码似乎工作正常，但它在页面末尾添加了句点（。）。如何删除点和来自哪里？感谢您的帮助！的代码

with open("strings.txt") as inf:
    for line in inf:
        line = line.rstrip()
        if line.isalnum():
            print("{} was ok".format(line))
        else:
            print("{} was invalid".format(line))

应该已生成以下输出：

5345m34534l was invalid.
no2no123non4 was ok.
noq234n5ioqw#% was invalid.
%#""SGMSGSER was invalid.
doghdp5234 was ok.
sg,dermoepm was invalid.
43453-frgsd was invalid.
hsth())) was invalid.
bmepm35wae was ok.
vmopaem2234+0+ was invalid.
gsdm12313 was ok.
gswrgsrdgrsgsig45 was ok.
)/(/)(#=%#)%/ was invalid.
++-+-+--+--+-+>-<+-<<_<-+>>++ was invalid.

您的程序生成了以下输出：

5345m34534l was invalid.
no2no123non4 was ok.
noq234n5ioqw#% was invalid.
%#""SGMSGSER was invalid.
doghdp5234 was ok.
sg,dermoepm was invalid.
43453-frgsd was invalid.
hsth())) was invalid.
bmepm35wae was ok.
vmopaem2234+0+ was invalid.
gsdm12313 was ok.
gswrgsrdgrsgsig45 was ok.
)/(/)(#=%#)%/ was invalid.
++-+-+--+--+-+>-<+-<<_<-+>>++. was invalid.

我不明白您在页面末尾与句点（。）相关的确切问题。但我可以告诉你的是，如果你想删除任何你不想要的角色，即修剪。你需要使用rstrip（）函数，它将参数作为“你要从右侧修剪的字符”。例如rstrip（ ''）。如果您想做任何其他事情，请告诉我们。

你的预期和实际输出看起来一样，所以我不明白你想说什么。

[编辑]发表评论后，我明白了你想说的话：

with open("strings.txt") as inf:
    for line in inf:
        line = line.rstrip(" .")  #added space and .(period) to strip
        if line.isalnum():
            print("{} was ok".format(line))
        else:
            print("{} was invalid".format(line))
