我正在使用python 2.7并且我遇到了一个我以前没有遇到的问题，当我打印某个字符串然后在同一行上的变量时，变量被打印在字符串上。例如脚本编码如此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，但我在相同的脚本中有各种变量和字符串相同的代码，它们都按预期出现，我已经尝试重命名变量并更改字符串但仍然没有区别，有任何人之前遇到此错误或有任何想法可能会发生这种情况？我可以根据要求发布代码。
非常感谢:)）
修改 这是代码 - 我知道我可能已经重复了几次，并且那里有不必要的库，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。

以下是输出示例

Width = 120 mm
答案 0 :(得分：2)
我强烈怀疑您认为ipRating的数据IP20实际上是\rIP20。那就是：你在变量的开头有一个杂散的0x13回车符。回车符正在将打印位置移动到行的开头，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", "")
。
答案 1 :(得分：0)
这是做你正在做的事情的正确方法。
print('IP Rating = %s' % ipRating)
或
print('IP Rating = %d' % ipRating)
这只是代码末尾所有print语句中的一个示例。
如果您要打印字符串变量，请使用％s或以其他方式使用％d。如果您还有其他问题，请询问。
