Python - 在字符串上打印变量

Question

我使用的是python 2.7，我有一个以前没有遇到过的问题，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。例如该脚本的编码如下:print 'IP Rating = ', ipRating，命令提示符中的输出将为'IP20ating = '。我不知道为什么会发生这种情况，但我在同一个脚本中对各种变量和字符串有相同的代码，它们都按预期出现，我尝试重命名变量并更改字符串，但仍然没有区别，有人吗之前遇到过此错误或知道为什么会发生这种情况？如果需要，我可以发布代码。非常感谢:)

编辑这是代码 - 我知道我可能重复了几次，里面有不必要的库，但我的工作方式是导入我可能需要的所有库，然后在最后删除不必要的代码。

这是一个示例输出

IP44ating =
Weight =  .51KGS
Projection =  35 mm
Diameter =  0 mm
Length =  0 mm
Height =  90 mm
Width =  120 mm

Answer 1

我强烈怀疑您认为是IP20的数据ipRating实际上是\rIP20。也就是说:变量开头有一个杂散的 0x13 回车符。回车符将打印位置移动到行首，然后变量将覆盖您之前打印的内容。

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。
