Python-在字符串上打印变量

我使用的是Python2.7，我遇到了一个以前从未遇到过的问题，当我打印某个字符串，然后在同一行上打印一个变量时，该变量会打印在字符串上。e、 g.脚本的编码类似于so

print'IP Rating='，ipRating

，命令提示符中的输出将是

'IP20ating='

。我不知道为什么会发生这种情况，但我在同一个脚本中为不同的变量和字符串编写了相同的代码，它们都如预期的那样出现，我尝试过重命名变量并更改字符串，但仍然没有区别，以前有人遇到过这种错误，或者知道为什么会发生这种情况吗？如果需要，我可以发布代码。 非常感谢：）

编辑 下面是代码-我知道我可能已经重复了几次，其中有不必要的库，但我的工作方式是导入所有可能需要的库，然后在最后删除不必要的代码

这是做你正在做的事情的正确方法

print('IP Rating = %s' % ipRating)

或

这只是代码末尾所有

print

语句中的一个示例

---

如果要打印字符串变量，请使用%s或%d。如果您还有任何问题，请提问。

我强烈怀疑您认为是

IP20

的数据

ipRating

实际上是

\rIP20

。也就是说：在变量的开头有一个零散的0x13回车字符。回车符将打印位置移动到行首，然后变量将覆盖之前打印的内容

您可以通过添加以下行来测试这是否是问题：

ipRating = ipRating.replace("\r", "")

---

在打印语句之前。

yes代码被请求，不要犹豫，请发布代码，您可以尝试一下：打印'IP Rating='，str（ipRating），所以您说ipRating变量的值为20，但打印时您得到'IP20ating='。。对吗？代码是这样的，@Trygve变量已经被格式化为字符串了，重新格式化会有什么不同吗？@Srivatsan就是这样，除了ipRating变量不总是20如果你打印“IP Rating={}”，会发生什么。格式化（ipRating）他使用的是Python2.7这是在Python2.7上完成的。它还支持基于功能的打印。如果您打算建议更改打印功能，那么更改格式功能是否也有意义<代码>打印（'IP等级={0}）.format（ipRating））@Remolten相同的输出，感谢您的建议和帮助though@CasualDemon同样的输出，该死的，这太令人沮丧了。hahaI现在就试试这个，让你知道输出是好的。但是，你应该试着找出迷路的角色是从哪里来的，而不是简单地掩盖裂缝。

print('IP Rating = %d' % ipRating)

ipRating = ipRating.replace("\r", "")
